4. With the connector still disconnected, do these input tests at the following connector.
 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 5.

1. Before testing the multiplex control system, troubleshoot the system using B-CAN System Diagnosis Test Mode A(see page 22-93).
2. Check the No. 10 (7.5 A) fuse in the under-dash fuse/relay box. If the fuse is blown, replace it and go to step 3.
3. Disconnect the under-dash fuse/relay box connectors E, F, R, and S. NOTE: All connector views are wire side of female terminals.
4. 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.
