When if an error occurs on the [[Xbox 360]], some segments of the [[Ring of Light]] on the [[RF Board]] will be solid or flashing red. Examining the LED pattern is used to determine the type of error.

{{toc|limit=3}}

== Failure Modes ==
The general nature of the failure can be determined by observing the red light lit on the front of the console. In order to get the exact error, see [[#Secondary Error Codes|Secondary Error Codes]].

=== Xbox 360 (Original) ===
On the [[Original Xbox 360]], the outer segments of the [[Ring of Light]] flash red to indicate the failure mode.

=== Xbox 360 S and E ===
On the [[Xbox 360 S]] and [[Xbox 360 E]], the outer segments of the [[Ring of Light]] can no longer turn red. Instead, the failure mode is indicated by either a solid red or flashing red power LED.

== Error Behavior ==

=== EC_BOOT ===
EC_BOOT is triggered when an error is detected by the [[SMC]] which causes the console to not be able to continue booting.

When an EC_BOOT error occurs, the SMC will reset and try again up to 5 times. If the 5th attempt is not successful, the console will remain in EC_BOOT.

The front panel indicates a [[#Failure Modes|Core Digital/System Component Failure]]. The [[#Secondary Error Codes|Secondary Error Code]] will reflect the error.

The console powered in this state indefinitely until a power off event occurs, where the console will return to standby.

=== EC_FATAL ===
EC_FATAL is triggered  by the [[SMC]] whenever a voltage PWRGD (Power Good) signal is absent, or the temperature data cannot be read from the [[ANA]]/[[HANA]].

In either case, the console may be dangerous to operate. As a result, when the [[SMC]] enters EC_FATAL, all devices will immediately be shut down and all controllable voltages will be turned off. The SMC does NOT wait for the DVD tray to close so that the system powers down as quickly as possible.

During EC_FATAL, the front panel indicates a [[#Failure Modes|Core Digital/System Component Failure]]. The [[#Secondary Error Codes|Secondary Error Code]] will reflect the error.

The console remains in this state indefinitely until a power off event occurs, where the console will return to standby.

=== EC_THERMAL ===
EC_THERMAL is triggered when the CPU, GPU, or eDRAM thermal diode exceeds its [[Thermal Algorithm#Trip Temperatures|Thermal Trip Temperature]]. All devices will immediately be shut down and all controllable voltages except [[Power Rails#V_12P0|V_12P0]] (which powers the fans) will be turned off. The SMC does NOT wait for the DVD tray to close so that the system powers down as quickly as possible.

The fans will run at full speed and power off events will be ignored.

The console will wait in this state for any of the following to occur:
* All thermal diodes reach safe levels
* Two minutes has passed
* A thermal diode continues to indicate overload for more than 5 seconds
* An [[#EC_FATAL|EC_FATAL]] error occurs

When any of the above occur, [[Power Rails#V_12P0|V_12P0]] will be turned off. The console will remain in this state indefinitely until a power off event occurs, where the console will return to standby.

=== EC_XSS ===
EC_XSS is triggered when an error detected by the [[XSS]] is reported to the [[SMC]].

If the error occurs before the SMC and XSS handshake, the SMC will reset and try again up to 5 times. If the 5th attempt is not successful, the console will remain in EC_XSS.

If the error occurs after the handshake, the SMC will not retry and remain in EC_XSS.

The front panel indicates a [[#Failure Modes|Core Digital/System Component Failure or a Universal Error Message]]. The [[#Secondary Error Codes|Secondary Error Code]] will reflect the error. For some codes, a [[#Universal Error Message|Universal Error Message]] will be displayed on screen.

The console powered in this state indefinitely until a power off event occurs, where the console will return to standby.

== UEM ==
When a non-critical [[#EC_XSS|EC_XSS]] error occurs, the '''U'''niversal '''E'''rror '''M'''essage is shown on screen.

The message contains instructions to contact Xbox Support and the [[#Secondary Error Codes|Secondary Error Code]] will be displayed converted from base-4 into decimal, with an E in front of it. For example, the [[Secondary Error Codes#1022|1022]] error will display "E 74".

</gallery>

== Secondary Error Codes ==
In addition to the nature of the failure, the console also generates a '''Secondary Error Code''' which can be viewed on the front panel [[Ring of Light]].

{{Template:Errors}}

=== Instructions ===
Once the console enters a [[#Failure Mode|failure mode]] and the red lights are displayed, the error code can be accessed via the following procedure. Be sure to reference the table below to reliably determine each value of the error code.

# While holding sync, press the eject button once. The first value of the error code is displayed.
# Continuing to hold sync, press the eject button again. The second value of the error code is displayed.
# Keep holding sync and press the eject button a third time. The third value of the error code is displayed.
# While still holding sync, press the eject button a fourth time. The fourth and final value of the error code is displayed.
# Holding sync and pressing the eject button a fifth time causes display to return to the [[#Failure Mode|failure mode]].
# Look up the code in the database below.

;Notes:
* The value of the code may not change between presses. For example, if the code is 0001, then 0, 0, 0, 1 will be displayed. It is important to take note of the value on every eject button press.
* Confirming that the error code sequence exits back to the [[#Failure Mode|failure mode]] with the fifth press of eject while holding sync is useful to confirm all 4 values of the error code have been retrieved.
* For some reason in early 2006, Microsoft changed the full ring of the secondary code to mean 4 instead of 0, but we're going to keep the meaning as 0 as this makes it easier to understand. Microsoft appeared to continue using 0 internally as well.

=== Xbox 360 (Original) ===
When retrieving the error code using the procedure above, the values are displayed by the outer segments of the [[Ring of Light]] rapidly flashing red.

=== SMC Errors ===
These errors are generated by the [[SMC]].

==== 0001 ====
ANA_V12P0_PWRGD is driven high by the [[ANA]] (later [[HANA]]) as long as the V_12P0 rail is within tolerance. If V_12P0 ever drops out of tolerance, the signal is de-asserted, causing the [[SMC]] to enter [[Errors#EC_FATAL|EC_FATAL]] and the 0001 code to be displayed on the front panel.

==== 0020 ====
After [[GPU]] power and clocking are available, the [[SMC]] starts [[SMC#seqUnReset|seqUnReset]] which releases the GPU from reset. It then waits for the GPU to assert GPU_RST_DONE. If the GPU_RST_DONE signal is not asserted in the time allotted, [[Errors#EC_BOOT|EC_BOOT]] will be reported. The SMC will retry 4 more times. If on the final attempt, GPU_RST_DONE is still not asserted, the SMC remains in EC_BOOT and the 0020 code is displayed on the front panel.

==== 0021 ====
After receiving GPU_RST_DONE during [[SMC#seqUnReset|seqUnReset]], the [[SMC]] monitors the [[PCIe]] L0 status and waits for the link to enter the L0 state. If the link does not enter the L0 state in the time allotted, [[Errors#EC_BOOT|EC_BOOT]] will be reported. The SMC will retry 4 more times. If on the final attempt, the link still does not enter L0 state, the SMC remains in EC_BOOT and the 0021 code is displayed on the front panel.

==== 0022 ====
After the [[PCIe]] link has entered the L0 state during [[SMC#seqUnReset|seqUnReset]], the SMC releases the [[CPU]] from reset. The CPU will run the [[Bootloaders]] and start the [[XSS]]. When the XSS starts, it will attempt to retrieve the power up cause from the SMC. If the SMC does not receive GetPowerUpCause in the time allotted, [[Errors#EC_BOOT|EC_BOOT]] will be reported. The SMC will retry 4 more times. If on the final attempt, GetPowerUpCause is still not received, the SMC remains in EC_BOOT and the 0022 code is displayed on the front panel.
