Errors
  |
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.
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.
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 Core Digital/System Component Failure. The 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 Core Digital/System Component Failure. The 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 Trip Temperature. All devices will immediately be shut down and all controllable voltages except 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 error occurs
When any of the above occur, 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 Core Digital/System Component Failure or a Universal Error Message. The Secondary Error Code will reflect the error. For some codes, a 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 error occurs, the Universal Error Message is shown on screen.
The message contains instructions to contact Xbox Support and the Secondary Error Code will be displayed converted from base-4 into decimal, with an E in front of it. For example, the 1022 error will display "E 74".
The E 74 Universal Error Message
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.
Instructions
Once the console enters a 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.
- 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 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.

Xbox 360 S
When retrieving the error code using the procedure above, the values are displayed by the outer segments of the Ring of Light rapidly flashing green, as the outer segments can no longer turn red.

Xbox 360 E
The outer ring of the Ring of Light on the Xbox 360 E can no longer light up in segments. When retrieving the error code using the procedure above, the values are displayed via the number of blinks. For example, if the ring blinks 2 times, and then pauses, and then blinks 2 times again, the value is 2.

After GPU power and clocking are available, the SMC starts 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, 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 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, 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.

After the PCIe link has entered the L0 state during 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, 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.
