Diagnostic Trouble Code (DTC) Information AUU-0002
Condition
The control module compares its configuration ID with the signal configuration transmitted on the control area network (CAN) by the central electronic module (CEM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The vehicle configuration file has too few parameters.
- Internal fault in the control module.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition on and battery voltage between 9 and 16 V.
- Ignition on for at least 60 seconds.
Substitute Value
- None.
Possible Source
- Disrupted communication between Accessory USB Unit (AUU) and central electronic module (CEM).
- Incorrect configuration ID (the control module is not intended for this vehicle, for example it is a used control module with different software/hardware).
- An internal program memory fault has occurred.
Fault symptom[s]
- USB unit/Does not work
