Wiper Signal Circuit

WIPER SIGNAL CIRCUIT

CIRCUIT DESCRIPTION

When the cruise control ECU (distance control ECU) detects that the wipers are operating, the dynamic laser cruise control system will be cancelled.

HINT: A wiper switch signal is sent to the distance control ECU via CAN and BEAN. Therefore if there are any malfunctions in this circuit, check for DTCs in the CAN communication and multiplex communication systems. When the wiper is in the LO or HI mode, the dynamic laser cruise control is automatically cancelled and goes into the standby mode. (In INT (intermittent operation) mode, the laser cruise control is not cancelled.)
