DTC Descriptor

DTC B3715 02

- Front Wiper Relay Drive Circuit Short to Ground

Diagnostic Fault Information

Circuit/System 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.

Conditions for Running the DTC

The BCM output is actively being requested.

Conditions for Setting the DTC

The BCM detects a short to ground in the wiper relay control circuit.

Action Taken When the DTC Sets

The BCM will not activate the output.

Conditions for Clearing the DTC

* The current DTC will become history when the request for the output is removed or when the condition for setting the fault is corrected.

* The history DTC will clear after 50 consecutive ignition cycles without a fault present.
