2. Remove the left kick panel.
3. Disconnect the under-dash fuse/relay box connectors.
NOTE: All connectors are wire side of female terminals.
4. Inspect the connector 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, go to step 5.
5. Reconnect the connectors to the under-dash fuse/relay box, turn the ignition switch ON (II), and make these input tests at the appropriate connectors on the under-dash fuse/relay box.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 6.
6. Disconnect the under-dash fuse/relay box connectors P (3O P) and W (5P), and make these input tests at the connector.
- If any test indicates a problem, find and correct the cause, the recheck the system.
- If all the input tests prove OK, reconnect the connectors to the fuse/relay box, then go to step 7.
Door Multiplex Control Unit
7. Remove the driver's door panel.
8. Disconnect the 23P connector from the door multiplex control unit.
9. 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, go to step 10.
10. Reconnect the connector to the door multiplex control unit, turn the ignition switch ON (II), and make these 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.
