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 multi-function switch.
