B2303 JEEP Description
The Body Control Module (BCM) provides a reference voltage on the wiper park switch sense circuit through a pull-up resistor that is connected to battery voltage. The Wiper Park Switch switches the signal circuit to the ground when the wiper motor is in the park position. The Diagnostic Trouble Code (DTC) sets when the BCM detects a short to ground on the Front Wiper Park Switch Sense circuit.
