Code B370C Pontiac Description
The windshield outside moisture sensor uses the moisture sensor signal 2 circuit to command wiper motor wipe cycles and to confirm the moisture sensor signal 1 is being received. If at anytime communication between the windshield outside moisture sensor and BCM is lost, the BCM will use the inputs from the windshield wiper/washer switch in the delay positions to operate the wiper motor at continuous variable delay intervals.
The Diagnostic Trouble Code (DTC) sets if an open, short to ground or a short to voltage has been detected on moisture sensor signal 2 circuit.

- Faulty Windshield Outside Moisture Sensor (Rain Sensor)
- Windshield Outside Moisture Sensor harness is open or shorted
- Windshield Outside Moisture Sensor circuit poor electrical connection
- Faulty Body Control Module (BCM)
