Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information AUD-B1A0813

Condition
The subwoofer has two loudspeaker elements, SUB 1 and SUB 2, and each element is driven by one channel.
The Audio module (AUD) checks the signal in the signal cable to element SUB 2.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- No signal on the signal cable to element SUB 2.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Start up of the MOST network.
- Request for self-test.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.





Substitute value
- None.

Possible source
- Open-circuit on the signal cable between the element SUB 2 and the control module.
- Open-circuit in the loudspeaker.
