Diagnostic Trouble Codes (DTCs)

The body control module (BCM) monitors the voltage on the windshield wiper switch signal 2 circuit for diagnostic purposes. If the circuit is shorted to voltage while the driver is commanded OFF, the BCM will store DTC B3717. If the circuit is shorted to ground while the driver is commanded ON, the BCM will store DTC B3718.
