Windshield Wiper
The MICU operation controls the windshield wiper operation according to the wiper switch signal, the washer switch signal, the windshield wiper motor auto-stop (AS) signal, and other input data. Intermittent wiper control, which is vehicle speed-dependent, as well as wiper control when starting up, is performed according to shift position signal, brake switch signal, parking brake switch signal, and vehicle speed signal in addition to wiper HI/LO, wiper mist operation, washer linkage, and other basic operations.
Washer
The MICU controls the washer motor with the signal inputs from the washer switch. The integral washer motor uses the differential pressure valves and spray can be switched between the windshield and rear window according to the rotating direction.
Auto Wiper Function
The auto wiper function is controlled by the MICU based on the automatic lighting/rain sensor signals received. The delay interval setting, the intermittent wiper operation, and the automatic mode switching (LO/HI) are controlled by the MICU. Also, the wiper rain sensitivity can be changed by operating the sensitivity controller on the wiper switch.
