The integrated audio module (IAM) checks DC voltage to the antenna amplifier.

The control module's test for the diagnostic trouble code (DTC) starts in the event of:

- Activated radio.
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.
