- All connector views are from the wire side of female terminals unless otherwise noted.

1. Remove the right kick panel.
2. Disconnect the 22P and 26P connectors, then remove the passenger's 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.




Reinstall the passenger's unit and reconnect the connectors to the unit
