Windshield Wiper and Washer Operation

GENERAL INFORMATION

WINDSHIELD WIPER AND WASHER OPERATION

Intermittent control (Vehicle speed-dependent variable type) [Initial condition: with function]









1. ETACS calculates the windshield intermittent wiper interval T1 from the position of the windshield intermittent wiper switch on the column switch and the vehicle speed signal (sent from the combination meter to ETACS via CAN communication).
NOTE:
Using the customization function, the vehicle speed-dependent intermittent function can be invalidated (Refer to Programming and Relearning).

2. When ETACS receives the ON signal of the windshield intermittent wiper switch, it turns the windshield wiper relay ON. When the wiper reaches the stop position, the windshield wiper auto-stop signal turns OFF, and the windshield wiper relay turns OFF.
When the intermittent time T1 calculated by step 1 has elapsed after the windshield wiper relay ON, the windshield wiper relay turns ON again, and the above-mentioned operation is repeated.
