When the ignition switch is at the ACC or ON position, if the windshield washer switch of the column switch is turned ON, the front ECU turns ON the windshield washer relay. The windshield wiper drive signal is turned ON in 0.3 seconds until three seconds after the windshield washer switch goes OFF to operate the windshield wiper continuously. When the windshield washer switch is turned ON, if the windshield wiper is operating intermittently, intermittent operations will be continued after continuous operations.

NOTE: The wiper drive signal output time varies according to the conditions. Refer to the following table for details.
