Checking The Wiring

Check the connections with regard to contact resistance, play and oxidation.

Check the signal cables between the Integrated Audio Module (IAM) and the speaker in the left-hand front door with regard to short circuits between the signal cables.

Measure between:

• Integrated Audio Module (IAM) #A4 and speaker #1 in left-hand front door.
• Integrated Audio Module (IAM) #A11 and speaker #2 in left-hand front door.

If no fault was detected, replace the speaker.

Remedy as necessary.
