The windshield wiper and washer are controlled by the
Smart Wiring System (SWS). For troubleshooting, refer to GROUP 54B, Troubleshooting ,
GROUP 54C, Troubleshooting , GROUP 54D, Troubleshooting or
GROUP 54E, Troubleshooting .
note
Even when the ETACS-ECU has failed, the windshield wiper 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 wiper can operate only when the ignition switch is
at the "ON" position.)
