1. Before troubleshooting the wiper/washer system, troubleshoot the B-CAN System Diagnosis Test Mode A.
2. Remove the dashboard lower cover.
3. Remove the steering coin-in covers.
4. Disconnect the 8P connector (A) from the wiper/washer switch (B).
5. 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 6.
6. With the connector 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, replace the wiper/washer switch (combination switch control unit).
