Windshield Washer Control Module: Testing and Inspection
Combination Switch Control Unit Input Test
1. Before troubleshooting the wiper/washer system, troubleshoot the B-CAN System Diagnosis Test Mode A.
2. Remove the steering column covers.
3. Remove the self-tapping screws, then disconnect the 12P connector (A) from the combination switch control unit (B).
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.
-
If the terminals look OK, go to step 5.
5. Reconnect the 12P connector to the combination switch 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, go to step 6.
