Checking the power supply and ground for the audio module (AUM)
Check the fuses for the main unit/audio module (AUM).
NOTE:
If a fuse is blown, check the circuit after the fuse before replacing the fuse. Check for a short-circuit to ground. Then replace the fuse.
Check the connector for the main unit/audio module (AUM). Check for contact resistance and oxidation.
Check the power supply cable for the main unit/audio module (AUM). Check for an open-circuit.
Check the ground cable between the main unit/audio module (AUM) and the ground terminal. Check for an open-circuit. Also check the ground terminal. Check for contact resistance and oxidation.
Remedy as necessary.
