Editing Syscon Error Codes

== Description ==
[[SC EEPROM|Syscon memory]] includes a 0x100-byte table for storing error codes. Each error code consists of 4 bytes and an additional 4 bytes for its timestamp. The table can hold up to 32 errors. When the table reaches its maximum capacity and a new error needs to be stored, Syscon will delete the oldest error.<br>

== How to get the syscon error log ==
If the PS3 still boots to the XMB and is able to install and run applications, you can use programs such as those listed at the top of the [[Platform_ID#Apps|Platform ID]] page.
If the PS3 fails to boot, you can still get the error log by connecting a PC to the PS3's UART port using a "USB to TTLUART Adapter" and running the errlog command. There is also the clearerrlog command to clear the error table (handy to avoid confusion with old error codes that might have accumulated along the months/years and not related to the actual problem).

== Error log format ==
There are 2 error log formats that depends of the syscon type: for [[Mullion]], or for [[Sherwood]].<br>
The error codes and the timestamps are stored in little endian (right to left)<br>
The timestamps are in J2000 format (number of elapsed seconds since 2000/1/1 12:00:00). They can be converted to the standard Unix epoch and then summed 30 years minus 12 hours (or 946684800 seconds). Check the link to the right for information: [https://stackoverflow.com/questions/35763357/conversion-from-unix-time-to-timestamp-starting-in-january-1-2000 1]<br>
If the battery was empty or removed when the error was triggered, the timestamp will be recorded as FFFFFFFF.<br>
If the battery is replaced but the time is not configured in GameOS either manually or by network, the error log will seem to store timestamps starting with a date around 2005/12/31 00:00:00 (0x0B488680).<!-- this needs confirmation--><br>
More info about error log timestamp formats and loops in the [[Talk:Syscon_Error_Codes | Talk page]]<br>
*[https://www.epochconverter.com/ Unix epoch] starts counting at 1970/1/1 00:00:00
*[https://en.wikipedia.org/wiki/Julian_year_%28astronomy%29#Epochs J2000 epoch] starts counting at 2000/1/1 12:00:00

<!-- It seems the error code FFFFFFFF represents the end of the loop. When the errorlog is cleared (empty) the first error is stored at most top, and the next errors follows an order from top to bottom. But after the errorlog is filled with 32 errors syscon needs to start overwriting the old errors by storing an aditional control error (FFFFFFFF) to indicate where the loop ends. In other words, when the errorlog is filled syscon needs to write 2 errors always, the real one and the control error (FFFFFFFF) displaced to a different offset -->

== Error code format ==
The error codes follows the format: '''<span style="background:#000000; color:#ffffff;">&thinsp;A&thinsp;</span><span style="background:#909090; color:#ffffff;">&thinsp;R&thinsp;</span><span style="background:#ffff80;">&thinsp;ST&thinsp;</span><span style="background:#bbbbff;">&thinsp;C&thinsp;</span><span style="background:#ff8080;">&thinsp;ERR&thinsp;</span>''', where:

'''<span style="background:#000000; color:#ffffff;">&thinsp;A&thinsp;</span>''' (Fixed)
'''A''' = This is always "A"


'''<span style="background:#909090; color:#ffffff;">&thinsp;R&thinsp;</span>''' (Reserved)
'''0-E''' = Unknown
*'''F''' = Frequent error (For example, Motherboard Damage/Breakdown, etc.)


'''<span style="background:#ffff80;">&thinsp;ST&thinsp;</span>''' (Step Number)
'''00-7F''' = Step Number of the Power On Sequence (POS). This is the Power On Self Test (POST) process. If successful, the BOOT process begins, which loads the OS. 


'''80''' = Static State (Power ON). The console completed the POST and was in a static state. An error occurred during the PS3 boot-up process.  If you encounter an error during gameplay, it may happen with Step No. 80. For instance, if your NEC/TOKINs are failing, you may experience 80 1002 errors.


'''90''' = Static State (Power OFF). The error happened when the PS3 was powering off. For example, if a problem causes the system to hang while shutting down the console will beep before powering off. An error with step no. 90 will be recorded in the errorlog.


'''A0''' = Immediately after SYSCON reset. When power is supplied to the PS3, it should enter Standby mode. Early "Phat" models will have a solid red LED illuminated to indicate Standby mode. The PS3 contains a Standby circuit that requires constant power so that it can wait for the user to turn on the console. Many other electronics also utilize this feature. This is also referred to as a Vampire circuit, as it uses constant power even when a user is not using the console. It enables the ability to turn it on remotely, thus mitigating the need to physically flip a switch.

The PS3 reset circuit comprises the SYSCON and its clock generating crystal, Bluetooth/WIFI card, front power/eject and LED panel, and thermal monitor ICs. The SYSCON must detect whether the console is being manually started with the power button or over Bluetooth using the controller, hence these modules must be powered. It is important to ensure proper functioning of the thermal monitors before releasing power to the Southbridge, CPU, or GPU. Neglecting this step could pose a fire hazard. The thermal monitors ICs serve as the PS3's fire alarms, and are critical safety equipment. 

If there is a hardware issue in the circuit, an error will occur after the SYSCON reset, preventing the console from powering on. Instead of a solid red LED, the front LED will flash red indefinitely upon plugging in the console, indicating an error with the standby circuit. There will also be associated error log in the syscon which can help identify the specific component causing the issue.

5v_MISC powers the reset circuit, consisting of SMD/SMT components and ICs that power the modules above. Please refer to the Service manual (if available) for details. In particular, in the COK-001 service manual, the circuit diagram is provided on page 23/45. From the diagram, it's evident that DC/DC converter IC6005 generates +3.3v_EVER, while IC6006 produces +1.8V_EVER, and IC6009 is responsible for generating +3.3V_THERMAL. These are the primary voltages utilized by the component in the reset circuit, such as the Wi-Fi/Bluetooth card necessary for initiating console startup remotely by pressing the PS button on the controller. 


'''<span style="background:#bbbbff;">&thinsp;C&thinsp;</span>''' (Category)
*'''1''' = System Error
*'''2''' = Fatal Error
*'''3''' = Booting Error 
*'''4''' = Data Error


'''<span style="background:#ff8080;">&thinsp;ERR&thinsp;</span>''' (Error)
*This is a 3-Digit error code that gives specific information about the issue. For example, System error 002 (1002) means "RSX VRM Failure." 

'''Discussion'''
----
The three-digit error code may repeat in other categories, but that does not necessarily indicate the same issue. System error <span style="background:#ff8080;">001</span> and Fatal error <span style="background:#ff8080;">001</span> don't mean the same thing. <span style="background:#bbbbff;">1</span><span style="background:#ff8080;">001</span> is "BE VRM Power Failure" and <span style="background:#bbbbff;">2</span><span style="background:#ff8080;">001</span> is "BE Error." We wouldn't be able to distinguish the <span style="background:#ff8080;">error</span> just by referencing it. This alone lacks sufficient information to comprehend the problem.  The <span style="background:#bbbbff;">category</span> gives the <span style="background:#ff8080;">error</span> context. To provide context, we use the 4-digit code <span style="background:#bbbbff;">C</span><span style="background:#ff8080;">ERR</span> to differentiate them from one another. 

Likewise, the <span style="background:#ffff80;">Step Nump (ST)</span> provides context to the 4-digit code. For example, you can have a CELL VRM Power Failure occur while playing an intense game (Static State, Power on). That would generate an <span style="background:#ffff80;">80</span><span style="background:#bbbbff;">1</span><span style="background:#ff8080;">001</span> (Step number <span style="background:#ffff80;">80</span>). However, this error can also occur when the console is turned on, during the Power On Sequence Testing (POST), before it has a chance to start the boot loader, which loads the operating system, which in turn allows you to load the game. This time, it might generate error <span style="background:#ffff80;">10</span><span style="background:#bbbbff;">1</span><span style="background:#ff8080;">001</span>. Step number <span style="background:#ffff80;">10</span> is lower than Step number <span style="background:#ffff80;">80</span>, telling you this <span style="background:#bbbbff;">1</span><span style="background:#ff8080;">001</span> occurred earlier. The <span style="background:#bbbbff;">Category</span> + <span style="background:#ff8080;">Error</span> tells you "What" happened. The <span style="background:#ffff80;">Step Number</span> tells you "when" it happened. It's building context that can help you figure out what is causing the error.

It's crucial to examine the entire error log, not just the 4-digit <span style="background:#bbbbff;">C</span><span style="background:#ff8080;">ERR</span>, to understand "why" the error occurred. In the previous example, the <span style="background:#000000; color:#ffffff;">A</span><span style="background:#909090; color:#ffffff;">0</span><span style="background:#ffff80;">80</span><span style="background:#bbbbff;">1</span><span style="background:#ff8080;">001</span> may indicate an issue with the NEC/TOKIN Proadlizers, a type of capacitor in the CELL CPU's VRM (voltage regulation module). Conversely, <span style="background:#000000; color:#ffffff;">A</span><span style="background:#909090; color:#ffffff;">0</span><span style="background:#ffff80;">10</span><span style="background:#bbbbff;">1</span><span style="background:#ff8080;">001</span> may result from various other factors, simply because there is a larger number of things that can go wrong. Therefore, it's possible that the NEC/TOKINs are not the source of the error.

All of this means you must be knowledgeable about the hardware to comprehend the errors stored in the SYSCON. Unfortunately, there is not a unique error code for every potential issue. For example, there is no error that can indicate if Capacitor C6900 is short. Nonetheless, there are a few exceptions, where a specific code typically conveys the same meaning. For example, a fuse that has blown "usually" causes said code. But we cannot dismiss the possibility that a cap blowing on the same line could also be the cause, however unlikely that may be.

*3034 errors are often caused by defects on the BGA or Bump (among other issues). Experienced PS3 repair technicians have noted that it is almost exclusive to the RSX. Although we cannot completely exclude the possibility of a CELL BE BGA/Bump defect being the cause, it has been the exception to the rule. Time and experience have demonstrated that 3034 errors are primarily an RSX problem. A repair technician needs to decide which processor to reball/replace based upon the more likely candidate and proceed accordingly, using their judgement.

The following error code section will only list the last 4 numbers (category + error). However, remember the Reserved Area and Step Number can be useful to figure out "when" the error occurred and how frequent it is. The last four numbers are the most important for figuring out what specific error means, but you still need to figure out what it means in context of your issue. So you can diagnose the error and then fix it.

== Error codes ==

=== System Errors===
----

==== 1001 (Power CELL) ====
*Components Involved:
**[[CELL BE|CELL]] (IC1001 on [[COK-001]])
**NEC/TOKIN Proadlizers (C6140/C6141/C6142/C6143 on [[COK-001]])
**Other nearby components of the power block

This error may result from inadequate filtering on the CPU's core voltage (VDDC) or an unexpected system shutdown. Voltage ripple or noise within a certain range could cause errors before they worsen into a [[CELL BE|CELL]] VDDC Power Failure (3003). There are several SMD filters, but the most critical ones are the NEC/TOKIN Proadlizers (capacitors). Bad NEC/TOKINs are responsible for 1002 errors on the GPU, but diagnosing 1001 errors is not as straightforward. You must observe the console experiencing YLOD while under load and confirm the generation of a new 1001 error. Otherwise, the 1001 code may indicate the console was not turned off correctly.

1001 errors can be recorded automatically when the system experiences an unexpected shutdown or loss of AC power. These errors frequently arise during testing when the console is frequently turned on or off instead of being gracefully shut down. A0801001 errors alone cannot prove that NEC/TOKINs are failing. Such errors are regularly found in the log of properly functioning machines and are not cause for concern unless the system is unexpectedly shutting down on its own.

A machine that can power on but displays graphical artifacts or no video may lead to misinterpretation of 1001 errors. In such cases, the console must be turned off forcibly using the power switch at the back of Phat/Fat models or by pulling the power cord in Slim and Super Slim models. This may cause 1001 or 1004 errors, which can be ignored if they were not generated under normal circumstances. If a console is showing artifacts/GLOD, fix the larger problem first (usually a GPU problem requiring a reball/replacement). Only after that, if stress testing results in 1001 errors, should you troubleshoot the CPU NEC/TOKINs.

Anecdote: One console, with faulty CPU NEC/TOKINs, displayed an A0901001 error only during shutdown. The Last of Us, a strenuous game, showed no signs of typical bad NEC/TOKIN behavior, and the system remained stable. However, it remained in shutdown for a prolonged period, resulting in the YLOD (3 beeps and flashing red light). It required a reset to power back on. Replacing the NEC/TOKINs resolved the problem.

==== 1002 (Power RSX) ====
*Components Involved:
**[[RSX]] (IC2001 on [[COK-001]])
**NEC/TOKIN Proadlizers (C6229/C6230/C6231/C6232 on [[COK-001]])
**Other nearby components of the power block

This error is linked to inadequate filtering on the '''RSX_VDDC''' power line. A certain range of voltage ripple and noise can trigger this error before it becomes severe enough to cause an RSX_VDDC Power Failure (3004). YLOD's that lead to 1002 errors vary in length, lasting from 2 seconds to only happening during intense games. <br>
<br>
There are a number of SMD components used in filtering, but the major concern is the NEC/TOKIN proadlizers (capacitors). 1002 errors indicate faulty NEC/TOKINs.

==== 1004 (Power AC/DC) ====
*Components Involved:
**[[Power Supply]]
When a console loses AC power, it may generate error A0801004. During the shutdown sequence, voltage regulators are turned off sequentially in reverse order to the Power On Sequence (POS). This allows components enough time to enter a power off state. It helps to prevents data corruption and voltage spikes or discharges that can damage sensitive components. 1004 errors commonly occur in machines that can power on but have graphical artifacts or no video, also known as GLOD. In such cases, the user has no choice but to improperly power off. Forcing a shutdown using the power rocker at the back of the console (for Phat models), or by pulling the power cord (for slim and super slim models) will cause an unexpected loss of AC power and prevent the SYSCON from completing the shutdown sequence. 


This error may be disregarded if it occurred due to abnormal circumstances, such as a power outage or accidental unplugging. Since it did not result from a hardware malfunction, it is not a significant concern. If a console displays artifacts or the GLOD, the main issue should be addressed first, typically involving a GPU problem requiring a reball or replacement. Afterward, if 1004 errors reoccur, the AC/DC line, PSU, and its connection to the DC-DC converters should be diagnosed.

==== 1103 (Thermal Alert SYSTEM) ====
*Components Involved:
**[[CELL BE|CELL]]
**[[Thermal|CELL temperature monitor]] (only in mullion syscons, the CELL temperature monitor for PS3 slims and super slims are unable to send this error code)
Syscons have a pad/pin specifically for this signal. It was given an official generic name (not indicating anything that triggers it) because several components can send it. In the first PS3 models (with mullion syscon?), the signal can be sent by CELL or the CELL temperature monitor using the official function names SYS_THR_ALRT or THERMAL_OVERLOAD.<br>

But this electrical design is not specific for the PS3, there could be other devices based on the IBM CELL, and developed by SONY, where this error code is sent by other components, which could have more than one CELL so in general we could say this error code indicates one (or more) of the CELL processors (and maybe other components not present in retail PS3 models or his temperature monitor chips) is overheating.

At least 3 consoles that had CPU trace damage resulting from failed IHS delid attempts exhibited A0801103 and A0902203 errors.

==== 1200 (Thermal CELL) ====
*Components Involved:
**[[CELL BE|CELL]]

CPU Overheat. This is a common error. The usual culprit is failed Thermal Interface Material (TIM). As the material ages it "dries" allowing air inside. Air is a heat insulator, reducing the TIM's ability to transfer enough heat away from the processor. The system fan will steadily get louder over time until it cannot keep up. Once the processor approaches it's Thermal Shutdown Temperature a Yellow LED begins flashing on the console (Early Phat Models). Once it reaches the Thermal Shutdown Temperature the console will beep three times and hard shutdown, flashing red until the console is unplugged and the error state reset. Error 1200 is generated in the SYSCON errorlog.

First be sure the system fan is working. If so, apply new TIM Between the Internal Heat Spreader (IHS) and Heatsink (HS). If that does not resolve the problem, carefully remove the IHS (Delid) and replace the TIM between the IHS and processor DIE.

If that still doesn't work, it could be an issue with the temperature monitor chip (IC1101). Beyond that, some users have noted that dead CPU's can throw error 1200. However, that's the limit of our current understanding. It could be dead, or have another unexplained issue, but usually reflowing or reballing is the last ditch effort to revive such a console.

==== 1201 (Thermal RSX) ====
*Components Involved:
**[[RSX]]

GPU Overheat. This is the same as error 1200 above, except it's for the GPU. The same repair steps apply, except it's Temperature Monitor Chip is IC2101. This error is rare. Out of hundreds of consoles and years of user reports this error has only occurred when the user forgot to replace the RSX heatsink when testing the console. It has not been reported under normal circumstances. The RSX tends to fail long before the TIM degrades to the point thermal shutdown is reached.

==== 1203 (Thermal CELL VR) ====
*Components Involved:
**[[CELL BE|CELL]] voltage regulators
**[[Thermal#Temperature_Monitors|Temperature Monitors]]

Some PS3 motherboards ([[TMU-520]], [[COK-001]], [[COK-002]]), have a temperature monitor located somewhere in the CELL power block. The other retail PS3 motherboard models doesnt meassures the temperature of the CELL VR

All the PS3 temperature monitor chips have a internal thermal sensor integrated + 2 pins for an optional external sensor. The temperature monitors for CELL and RSX are configured to use the external sensor, but this one for CELL VR probably uses the internal

==== 1204 (Thermal South Bridge) ====
*Components Involved:
**[[South Bridge]]

==== 1205 (Thermal EE/GS) ====
*Components Involved:
**[[CXD2953AGB]] or [[CXD2972GB]]
**See also: [[PS2 Compatibility|Emotion Engine / Graphics Synthesizer]]

This error is specific for [[COK-001]]/[[CXD2953AGB]] (with full PS2 hardware compatibility, EE+GS) or [[COK-002]]/[[CXD2972GB]] (with partial PS2 hardware compatibility, GS only)

==== 1301 ([[CELL BE|CELL]] PLL Unlock) ====

Has been reported in a console where the CPU die was chipped during a delid attempt gone wrong. The console exhibited a Green Light of Death (GLOD) and shutting down periodically with A0801301.

On another console 1301 occurred after both the CPU and RSX were reballed. The reball of cell likely failed, or damaged it.

On a third console it was reported after nearly every chip on the Motherboard was heat gunned. They probably didn't achieve the necessary temperatures to reflow the CPU, and if they did they probably damaged it by using too much heat.

In all 3 cases the CPU was damaged or heated in some way.

==== 14FF (Check Stop) ====

This error can occur when the console was on at the time the YLOD occurred. On consoles exhibiting this error, subsequent attempts to start the console resulted in a GLOD with 1601/1701 errors, or a YLOD within 2 seconds. SYSCON errors usually show one A0801601/A0801701 occurring at the same timestamp, followed thereafter by 3034/4xxx errors for all subsequent attempts to PWR it on. Or it'll GLOD and throw more 1701/1601's. The working theory is that there is a precarious solder joint (BGA or bump defect) teetering on the edge of breaking. It'll soon switch to 3034 with or without 4xxx errors.

Complicating the issue is the fact that sometimes people will get a 1301 or 1802 also. It likely has to do with where the joints are failing and it's involving those sub systems briefly before fully breaking.

Unlike Livelocks, which can be caused by both hardware and software conditions, Checkstops are a hardware issue. A checkstop occurs when the CPU or GPU, cache, memory, or I/O bus controller, finds something in an impossible state (impossible unless the Hardware is broken). The error isn't identified as a particular bus transfer in progress, or the CPU/GPU detects the console is stuck (frozen, no progress being made with that operation). When nothing can be done for a long enough period of time, the checkstop errors is logged and BE ATTENTION is driven High. SYSCON immediately shuts the console down with error A08014FF and A0801701.

The most likely cause of the error is a failing GPU (RSX) solder joint (BGA or Bumps). A distant second is a failing CPU (CELL) solder joint (BGA).

==== 1601 ([[CELL BE|CELL]] Livelock Detection) ====

CPU is deadlocked and cannot proceed. Some kind of error occurred, preventing a process from completing. It is the software equivalent of trying to pass someone in a hallway and you both keep choosing the same direction to swerve. Now imagine you had exactly 30s to make it to the other end of the hallway to catch an elevator, and it takes 29s to get there. Neither of you can pass and miss your elevators because of it. Now imagine you were supposed to pass an envelope to a person on the 3d floor, who had 30s to read it and enter it in a spreadhseet. Now he misses his deadline too. And imagine the entire organization was micromanaged like this. One disruption can cause the whole operation to grind to a halt! That's kinda how this works.

Basically this means the console froze and had to reboot. In the PS3 this is often preceded by graphical artifacting. The cause is often a solder joint on the RSX (BGA or Bumps). Generally these errors are seen in the early stages of a GPU failure. However CPU failures cannot be ruled out. They are just less likely.

Speculation:

As the impedance of propagating solder cracks increases, the digital logic core has a harder time calibrating the FlexIO during BitTraining. Once impedance reaches the limits of the compensation network, interference causes random issues during software execution. LiveLock conditions cause BE Attention signal to be driven High and the SYSCON shuts the console down (YLOD) with errors A0801601 and A0801701.

As the console cools the microscopic gaps in the solder can be physically reconnected by thermal warping. Warping is due to differences in the Coefficients of Thermal Expansion (CTE) between materials in the motherboard and processor. This expansion and contraction can reconnect the solder joints just enough to allow the console to boot. Or it may disconnect them. 
*If they reconnected, the console will boot until it experiances another 1601/1701 event.
*It they do not reconnect, the console cannot complete BitTraining and will fail in POST with error A0403034. Often with an associated Data error, such as A0404401 (if the broken solder joint affected a Data line on one of the SPI lines). If there is no Data error, the broken joint only affected the voltage for the SPI line. Either RSX_VDDR or YC_RC_VDDIO. 

If a YLOD turns into a GLOD after reball/reflow then 1601 (with or without 1701) could mean the [[RSX]] RAM was damaged. This is a loose association based on a few user reports.

==== 1701 ([[CELL BE|CELL]] BE ATTENTION) ====

BE ATTENTION is an active-high output flag sent by the CPU to the SYSCON. During initialization & configuration it is used to request an operation by the SYSCON. When ATTN goes High the syscon reads the SPI Status Register to determine the cause of the Attention signal. It remains high until software resets the condition that caused it.

After Power On Reset the BE attention signal is driven low and is supposed to stay there! If there is a Checkstop error (14FF), Livelock Detection (1601), or PLL Unlock (1301) the CPU enters a fault condition and raises the Attention signal (1701) during operation. The SYSCON sees this and immediately shuts the console down with error code A0801701 and usually another error indicating the cause. One common way this happens is when a solder connection breaks while the system is on. This could be the BGA (Ball Grid Array) or the Solder Bumps under the die.

Going into more detail, BE Attention is used during Power On Reset (POR)...
*To load CPU VID voltage from the VRM internal registers.
*To Write configuration-ring data (Important CPU Config settings that should only be modified at boot, otherwise errors can occur).
*To calibrate the FlexIO interface (BitTraining).

If Attention occurs during the Power ON State (Step# 80) it indicates an error condition. Basically, something is flagged by the Processor as abnormal. It's forced to attempt to resolve the problem before it can continue with whatever it was trying to do. If the error condition cannot be resolved, the CPU sends the ATTENTION signal to the SYSCON. The SYSCON immediately shuts off the console, then reads the SPI Status Register to determin the cause. Then it records the A0801701 in it's errorlog along with the specific cause (if it determined one). Errors that can cause the Attention include:
*Unresolved Checkstop errors (14FF)
*Livelock Detection (1601)
*PLL Unlock Condition (1301)
*BGA/Bump Defect that occurs while the Console was On (Step# 80). Subsequent attempts to power on the console would result in 3034/4xxx errors.

A user get this error code with a damaged hard drive. He was transfering some games via FTP, and his console turned off with Ylod. When he tried to turn on again, he get a Glod. Problem was fixed just by changing the HDD.

1701 has been reported from using homebrew apps that caused a software conflict. Uninstalling the software can resolve the issue. It that's not possible because the system is locked up, it may be necessary to restore the operating system (OS).

==== 1802 ([[RSX]] Initialization) ====

A0201802 is the error the SYSCON will return when there is no RSX installed at all! Step# 20 is when the RSX is first Initialized. So if it's not responding that early in the Power On Sequence, then it's Dead-Dead or completely missing!

A0801802 is occuring after the console has booted (step# 80) and causes BE Attention (1701) alarm raised when a Checkstop error (14FF) occurs. Likely the 1802 was the hardware failure that caused the checkstop error. That causes BE ATTENTION to be driven High and the SYSCON shuts the console down with A0801802, A08014FF, and A0801701. That makes sense because the CPU couldn't continue with it's process when the RSX interrupt occurred. These errors have been seen in consoles that were repaired by an RSX reball/replacement.

*This fatal error codes seems to be repeated up to 3 times for 3 special cases, as example, errors '''20'''03, '''21'''03, and '''22'''03 are related with southbridge, the only thing that changes in the error code is the second digit (located inmediatly after the category 2).

==== 2022 (DVE) ====

DVE Error (IC2406, CXM4024R MultiAV controller for analog out)

This error occurs when you see no video out using HDMI on any Samsung Smart TV.

You can intentionally produce this error code by making the TV detect another console first (a PS4), turn off the TV, swap the HDMI cable from the PS4 to the PS3, and turning back on the TV. You can fix this error code by replugging it in while the TV is on.

This error is also present when the console produces graphical artifacts on the screen. The console freezes and cannot be used, forcing the user to turn off the console. This produces the 2022 error code and is an early sign of GLOD.

==== 2024 (AV) ====
This error tends to cause a delayed Yellow Light Of Death (10s - 1min). Sometimes described as a Green Light Of Death (GLOD) or Red Light Of Death (RLOD). 

2124 and 2024 errors have been fixed by replacing both the AV and HDMI encoders. One user reported 2024/2124 errors resolved by replacing the HDMI encoder. Another removed the HDMI encoder and tested the console without it. That console primarily filled the errorlog with 2124 errors, but a few 2024's as well. So it is unclear if 2124 is specific to the HDMI Encoder or AV Encoder. It seems it could be either.

==== 2103 (South Bridge) ====
Southbridge Error (IC3001)

==== 2110 (Clock Subsystems) ====

Clock Generator Error (IC5001)

This error can be caused by a 5V_MISC short to ground. One user had an A0022110 after replacing IC6105 (Buck Converter) and accidentally bridging the 5V voltage input. So check the 5V line for shorts.

This error has been resolved by a number of users who had a short on F6001. It is important to note that something usually causes that fuse to blow, like a short. So it's important to troubleshoot the board to find and repair the shorting component before replacing the fuse. Otherwise the new one will blow too.

One user, who resolved this error on his C model PS3, noted "very short YLOD. Error code shows 2110[...]Some earlier code shows 1001 and 1002." The 1001 & 1002 errors he noted in the log before the 2110 appeared may have been a clue that C6019 or C6020 (as they are in parallel) was deteriorating. Further investigation is needed to confirm this hypothesis, however. In his case, C6019 was shorting and caused F6001 to blow. This short overloaded F6001 and cut power to many Subsystems, such as the HDD, USB ports, South bridge, CPU, GPU, etc.
Another user confirmed this. The error log was showing code 2110 and one entry earlier was showing code 1001. Checking both capacitors after removing them from the board, confirmed that one capacitor was reading 140 ohms and not reading as a capacitor, so it was working as a resistor causing extra load in the fuse.

One particularly noteworthy component is IC6020, which supplys +3.3v_MK_Vdd to the clock generator (IC5001). When F6001 blows, a 02 2110 is generated. A step number of 02 is very early in the power on sequence (POS), which explains why 2110 is triggered instead of another error code. Since the clock generator is critical for timing, it is one of the first things the SYSCON checks during the POS.

Clock Generator Error (IC5003)

==== 2112 (Clock CELL) ====
Clock Generator Error (IC5002)

Clock Generator Error (IC5004)

Analog Voltage for the core PLL of IC5004, which is an ICS9214 Clock Generator used to support the Rambus XDR memory subsystem and Redwood logic interface.

SW_1_B enables control Pin 5 on IC6013, which generates +2.5V_LREG_XCG_500_MEM. If that fails it generates A0092113.

==== 2120 (HDMI) ====
HDMI Error (IC2502)

A0202120/A0213013 error combinations are common. They appear to be related to VDDIO. IC6301 is involved in the formation of +1.7V_MISC, which amonge other things provides input power to the DC-DC converters that output +1.2V_YC_RC_VDDIO, +1.5V_YC_RC_VDDA, +1.2V_SB_VDDC and +1.2V_SB_VDDR. Lack of voltage to these DC/DC converters downstream of IC6301 suggests F6302 has blown. A number of people have fixed these 2120/3013 errors by finding shorts at or near C6320 and replacing Fuse F6302. But there are many other SMD nearby that might cause these fuses to blow. So you will need to track the source of the short and fix it, or the fuse will just blow again.

A bad thermistor (TH2501) has been reported to cause A0002120.

A0802120 and A0902120 errors may be related to the actual HDMI transmitter (IC2502). Or they can be caused by BGA/Bump defects affecting VDDIO, on the RSX or CELL. BGA defects on the RSX VDDIO pads have been confirmed with a pressure test to have caused 2120 errors.

Power Failure

==== 3001 ====
12v Power Failure

Usually this caused by a bad Power Supply Unit (PSU). 

Alternatively, a failure on the 12v_main line can cause it. Check fuses, capacitors, resistors, and IC's on the 12v line. Measure resistance of the large 2 prong 12v connector on the motherboard. It should read in the Kilo ohms range if there is sufficient separation. Otherwise you may have a short somewhere on the line.

==== 3002 ====
Power Failure

==== 3003 ([[CELL BE|CELL]] Core Power Failure) ====

This error will occur in the case of a PWR failure on the main core voltage of the CPU (VDDC). For example, if the filtering capacitors (NEC/TOKIN's) are severely damaged. There are other SMD's in that filter, so it could be related to them as well.

A shorted Blu-Ray drive can cause this error as well. Be sure that your drive is going well before doing anything on your console.

==== 3004 ([[RSX]] Core Power Failure) ====

This error will occur in the case of a PWR failure on the main core voltage of the GPU (VDDC). For example, if the filtering capacitors (NEC/TOKIN's) are severely damaged. There are other SMD's in that filter, so it could be related to them as well.

[[CELL BE|CELL]] Error

Observations: 
A user triggered this error by injecting 3.3V into PWRGD (power good) of IC6103 (NCP5318 CPU Buck Controller). It generated error 20 1001 and 20 3010.
Another user (Razmann4k) got this error on their CECHL04 by attempting the eraser mod on an already delidded Cell and noticed a crack running down the middle of the Cell die. It caused 20 3010.


This problem may be related to the PLL signal generator circuit, open resistors, crystal oscillator or even the integrated itself (CDC735/CDC736/4227ANLG)

BE_SPI DI/DO ERROR

[[CELL BE|CELL]] not communicating to syscon via SPI (1.2V MC2_VDDIO and 1.2V BE_VCS no output) = Possible shorts on the line, check C4001 and trailing caps. Possible dead CPU? 

Another user had one on a CPU he damaged while deliding.

A0212120/A0213013 error combinations are common. They appear to be related to VDDIO. IC6301 is involved in the formation of +1.7V_MISC, which among other things provides input power to the DC-DC converters that output +1.2V_YC_RC_VDDIO, +1.5V_YC_RC_VDDA, +1.2V_SB_VDDC and +1.2V_SB_VDDR. Lack of voltage to these DC/DC converters downstream of IC6301 suggests F6302 has blown. A number of people have fixed these 2120/3013 errors by finding shorts at or near C6320 and replacing Fuse F6302. But there are many other SMD nearby that might cause these fuses to blow. So you will need to track the source of the short and fix it, or the fuse will just blow again.

One person reported A0202120/A0213013 when his CPU substrate (interposer) was cracked in half by a failed delid attempt.

Through sabotage testing is was found that disabling +1.2V_YC_RC_VDDIO caused A0213013.

Also through sabotage testing, it was found that when L6305 is removed it cut's off +1.8V_RSX_FBVDDQ (VRAM voltage). It caused a 10x A0202120 & 1x A0213013 error combo.

[[CELL BE|CELL]] / [[RSX]] Communication Error

This error occurs when Bit Training fails. Bit Training, also know as bit calibration, is a critical process during the power-on-reset (POR) sequence of the CELL BE processor. It fine-tunes the behavior of individual bits within the 8-bit-wide Rambus channels. This adjustment accounts for variations in circuitry, wiring, and loading delays. Bit training plays a pivotal role in optimizing signal quality by calibrating the signal driver current, driver impedance, and ensuring that the timing of each of the eight data bits aligns with clock edges, effectively centering the data "eye" allowing for more accurate and reliable data transmission.

This is the most common error seen in early Phat model PS3's with the 90nm [[RSX]]. It is the hallmark of solder fatigue (such as a cracked solder ball or bump defect) which affects the Flex IO interface that allows the CPU, GPU, and SB to communicate. It is by no means limited to the early models, however. These errors have been seen in every model of PS3 with varying frequency. However, it's most common in the earliest models, likely due to a manufacturing defect in the 90nm RSX material set. Namely a CTE mismatch between underill and bump material that leads to premature solder fatigue and GPU failure. Dubbed "BumpGate," this is a well known failure modality among GPUs manufactured from 2005-2008. Although it has not been proven unequivocally that the 90nm RSX is affected by Bumpgate, members of the community have shown the 90nm RSX has an increased failure rate, similar material set, and exhibits similar symptoms to known bumpgate affected chipsets - such as black screens (GLOD), graphical artifacts like lines, double images, color splotches and pixelation, and etc. 

While Bumpgate is a plausible explanation, it's not the only one. The materials used to construct the motherboard and processors have different coefficient of thermal expansion (CTE). This means they will expand and contract at different rates as the chip heats up and cools down, which applies force to solder connections. Over many thermal cycle this deforms the solder and causes a defect. That may affect the Bumps, which attach the silicon die to the interposer (sometimes referred to as substrate) or the Ball-Grid Array (BGA) which connects the interposer to the Motherboard. 

3034 is triggered when Bit calibration, also known as BitTraining, cannot complete correctly. So it is not limited to a singular cause. BGA defects from thermal cycling, drop damage, pulling force from separating the heat sink from the processors while disassembling, or delidding can occur. The bumps on CPU, GPU, or SB can fail, Flex IO traces that connect them can be broken/scratched, or accumulated damage from wear and tear (electromigration) can also cause BitTraining to fail. Anything that can disrupt the impedance of the FlexIO can cause BitTraining to fail. A skilled technition will need to use deductive reasoning to diagnose the cause and choose the appropriate repair.

A qualitative test known as a "pressure test" may be used to help make a diagnosis. Applying slight pressure, within reason (not your body weight or clamping force which could cause a BGA defect), to the processor flexes the motherboatd beneath the BGA and "may" temporarily reconnect a solder ball with it's pad. Like holding 2 wires together. This can cause flickering on screen, a console to power on when it couldn't before, etc. If the console or error responds differently when pressure is applied, this may be taken as  evidence of a BGA defect. It is not difinitive, but tips the odds in favor of that diagnosis. A reball in that case may be sucessful. However, if it does not respond to pressure is not likely to be the BGA and another explnation, such as bumps are more likely. It should be noted that bumps can be affected by force as well, but because the underfill suppots them, it generally requires more force to reconnect them using this method. This is what the "Bolt mod," comonly performed on the XBOX 360 did. That much force permantly deforms the motherboard and causes irreparable damage. DO NOT DO THIS! But it illistrates the point. You don't need much force to see if the BGA is affected and if it responds to light pressure, it's unlikely to be the bumps. Therefore, taken together with other clues, it can be helpful to a skilled technition gathering evidence for a diagnosis. 

In consoles with a 90nm [[RSX]] (CECH-Axx/Bxx/Cxx/Exx/Gxx/Hxx, and M03 models) the most likely cause of a 3034 is the GPU itself. It can be replaced with another 90nm RSX without modification. However, it can also be replaced with a more reliable 65nm or 40nm model, using a process nicknamed a "Frankenstein Mod." SONY service technicians performed this modification in some officially refurbished consoles. The PS3 community has developed a method as well. Since there is a question about the 90nm RSX's reliability and both a reball and Frankenstein mod require the 90nm to be desoldered, it is advisable to replace the 90nm GPU with a more reliable model instead of risking another 90nm GPU. Rework is hard on the motherboard and surrounding components, so choosing a repair with the fewest uncertainty's is wise.

In models without the 90nm RSX, 3034 is still possible, but far less likely to be caused by the GPU. CPU BGA defects are common in dropped consoles, those that have been delided or have trace damage to the area around the processors. So troubleshooting is necessary to make a diagnosis.

Flash

A0603040 is know to be caused by not soldering the flash (NAND/NOR) back on properly. It happens when the flash is not powered. Step #60 is when the StarShip 2 flash controller and NAND/NOR are initialized, kicking off the firmware sequence that loads the Operating System. Check their voltages and be sure the FW is not corrupt. If you have a backup, you could try replacing the Flash to see if a module failed.

----
*This error codes seems to be repeated up to 5 times for 5 special cases, as example, errors 4'''0'''01, 4'''1'''01, 4'''2'''01, 4'''3'''01, 4'''4'''01 are related to CELL, the only thing that changes in the error code is the second digit (located inmediatly after the category). If at some point we find what means that digit we can join the wiki page sections together (with titles: "4001, 4101, 4201, 4301, 4401", etc...)
