DESCRIPTION

Tech Tips
A wiper switch signal is sent to the driving support ECU via the CAN. If there are any malfunctions in this circuit, check for DTCs in the CAN communication system. When the wiper is in the HI mode, the dynamic radar cruise control is automatically canceled and goes into the standby mode.
