OnStar Buttons and Microphone Input Test
1. Inspect the connector and socket terminals to be sure they are all making good contact.
• If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
• If the terminals look OK, make the following input tests at the connector.
— If any test indicates a problem, find and correct the cause, then recheck the system.
— If all the input tests prove OK, the switches and microphone must be faulty; replace it.
NOTE: No. 1, 12 and 16 terminals are automatic inside dimming mirror power, ground and signal lines.
