5. Remove the passenger's under-dash fuse/relay box (see page 22-86).
6. Remove the passenger's multiplex control unit from the passenger's under-dash fuse/relay box, and disconnect
its connector.
7. Inspect all connector and socket terminals to be sure they are 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 8.
8. With the passenger's multiplex control unit still disconnected, make these 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.
