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 a test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, substitute a known-good control unit, and recheck the system.

NOTE:
- If all the control unit (steering column, power seat, power mirror) input tests prove OK, disconnect all three control units, and check for opens or shorts in the communication lines.
- All connector views are from wire side of female terminals.
