Washer Signal Circuit

CRUISE CONTROL: DYNAMIC LASER CRUISE CONTROL SYSTEM: Washer Signal Circuit
- Washer Signal Circuit

DESCRIPTION

The distance control ECU detects washer operation. The cruise control will be cancelled by the distance control ECU if the windshield wipers operate in the HI or LO mode. By detecting washer operation, the distance control ECU allows the cruise control to continue even when the windshield wipers operate in the HI or LO mode.
