System Features

Rain Sensor Module 

The Microprocessor-based Rain Sensor Module (RSM) senses moisture on the outside of the windshield glass, and sends a wipe command to the Body Control Module (BCM). The RSM sends a wipe command to the BCM over the PCI data bus. The BCM then activates or deactivates the front wiper system. Sensitivity inputs are based on the driver-selected settings on the right side multifunction switch.

Speed Sensitive Intermittent Wipe Mode 

There are 5 individual delay times with a minimum delay of 1/2 second to a maximum of 18 seconds. When the vehicle speed is under 10 MPH (16 kmh), the delay time is doubled providing a range of 1 second to 36 seconds.

Mist Wipe 

The wiper operates as long as the wiper switch is in the mist position.

Park after Ignition Off 

Because the wiper relays are powered from the battery the BCM can run the wipers to park after the ignition is turned off.

Wipe after Wash 

When the driver presses the wash button and then releases it, the wiper will continue to run for 3 additional wipe cycles.

The wiper system utilizes the BCM to control the on/off relay for low wiper functions, intermittent wiper delay as the switch position changes, wipe after wash mode, and wiper motor park functions. The BCM uses the vehicle speed input to double the usual delay time below 10 MPH (16 kmh).
