WINDSHIELD WIPER AND WASHER DIAGNOSIS

The windshield wiper and washer are controlled by the Simplified Wiring System (SWS). For troubleshooting, refer to SYMPTOM CHART .

Note. Even when the ETACS-ECU has failed, the windshield wipers can work at low speed as fail-safe mode. (Normally, the windshield wiper operates when the ignition switch is at the "ACC" position. But, if it enters the fail-safe mode, the wipers can operate only when the ignition switch is at the "ON" position).

REAR WIPER AND WASHER DIAGNOSIS

The rear wiper and washer are controlled by the Simplified Wiring System (SWS). For troubleshooting, refer to SYMPTOM CHART .
