Code B3717 Pontiac Description

The Body Control Module (BCM) monitors the control circuit of the wiper relay. The voltage level should be low while the wiper relay is de-energized and near system voltage when the relay is energized. After the BCM receives a low, intermittent, or mist signal from the wiper/washer switch, it responds by applying battery voltage through the wiper relay control circuit to the coil side of the relay, energizing the wiper relay. The Diagnostic Trouble Code (DTC) sets if the BCM detects a short to ground in the wiper relay control circuit.
