B370C Saturn Code - Rain Sensor Intensity Signal Circuit
Quick Answer
Ignition voltage is supplied to the windshield outside moisture sensor from the Body Control Module (BCM). Common causes include Faulty Windshield Outside Moisture Sensor (Rain Sensor), Windshield Outside Moisture Sensor harness is open or shorted, Windshield Outside Moisture Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B370C Saturn 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.
What are the Possible Causes of the DTC B370C Saturn?
- 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)
