Combination Switch Control Unit Input Test

Combination Switch Control Unit Input Test

NOTE: Before testing, troubleshoot B-CAN System Diagnosis Test Mode A.

1. Turn the ignition switch ON (II), remove the driver's dashboard undercover, and the driver's dashboard lower cover, then remove the steering column covers.
2. Disconnect the 8P connector from the wiper/washer switch (combination switch control unit).






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. Reconnect the connector to the wiper/washer switch, 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 5.






5. Disconnect the 8P connector from the wiper/washer switch, 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, the combination switch control unit must be faulty, replace the wiper/washer switch.
