Circuit/System Description
WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
The windshield washer system allows the driver to clean the vehicle's windshield using a discrete switch. The washer system uses the S82 Windshield Wiper and Washer Switch as the primary means of driver control. The S82 Windshield Wiper and Washer Switch is a discrete input to the K9 Body Control Module. The K9 Body Control Module communicates with the K219 Lighting Control Module over CAN to control G24 Windshield Washer Pump activation. The K9 Body Control Module also communicates with the K219 Lighting Control Module to control B+ to the M75 Windshield Wiper Motor during operation.
