Washer System

When the wiper/washer switch is placed in the rear WASH position, the SCCM (Steering Column Control Module) sends the request to the windshield wiper motor through the LIN (Local Interconnect Network). The windshield wiper motor grounds the rear washer relay directing washer fluid to the rear window.

Reverse Gear Wipe

When the wiper/washer switch is in any position other than OFF (or moisture is detected on the windshield if equipped with rain sensitive wipers) and the transmission selector lever is placed in the REVERSE position, the rear window wiper activates automatically. This feature can be enabled/disabled through the message center. For additional information on enabling/disabling this feature, refer to the Owner's Literature.

Rear Wiper Operation

When the wiper/washer switch is in the INT 1 or INT 2 position, the SCCM (Steering Column Control Module) sends the request to the windshield wiper motor through the LIN (Local Interconnect Network). When the request is received, the windshield wiper motor supplies a ground signal to an integral relay within the rear window wiper motor which activates the motor. The position of the wiper/washer switch determines how often the windshield wiper motor supplies the ground signal. The rear window wiper motor is self parking.
