Wiper Signal Circuit

Wiper Signal Circuit

DESCRIPTION

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

HINT: A wiper switch signal is sent to the distance control ECU via the CAN and BEAN. 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 HI mode, the dynamic radar cruise control is automatically canceled and goes into the standby mode.
