Diagnostic Error Codes If an error is detected, the following appears: Large X on the left side of the device icon. Device ID (three digits). Error code (two digits). FRU code (four digits). The device ID and error code indicate the detailed portion of the FRU that caused the error. If replacing a FRU does not correct the problem, see the device ID or error code from the previous failure. If they have changed, the cause might be that the new FRU is detective or that the FRU was incorrectly installed. Device ID: If an error is detected by the diagnostic tests, a three-digit device ID is displayed, indicating the suspected device.
