OnStar Control Unit Input Test

1. Remove the rear seat (Refer to the '96 - '01 3.5RL Service Manual, P/N 61SZ305, for the items not shown in this sec-

tion).

2. Disconnect the 32P connectors from the OnStar control unit.

3. 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 control unit must be faulty; replace it.
