Entry Light Control System
Control Unit Input Test (cont'd)
NOTE:
• Before testing, go to the Troubleshooting Guide (see page 23-244).
• All connector views are from the wire side of female terminals unless otherwise noted.
Multiplex Control Unit (Driver's):
1. Remove the under-dash fuse/relay box (see page 23-66).
2. Remove the driver's unit from the under-dash fuse/relay box (see page 23-247).
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 and the fuse/relay box socket.
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.
Reconnect the connectors to the unit.
