1. Remove the driver's dashboard lower cover.
2. Disconnect the under-dash fuse/relay box connectors C, E, F, J, K, 0, P, Q, X and Y.
NOTE: All connectors are wire side of female terminals.
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, go to step 4.
4. With the connectors still disconnected, 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, go to step 5.
