SYMPTOM
WIPER PARK SWITCH FAILURE

WHEN MONITORED
The ignition must be in the run position and battery voltage supplied to the BCM on the Fused B(+) circuit.

SET CONDITION
The code will set if the BCM does not detect a low to high voltage transition on the Wiper Park Switch Sense circuit within 8 seconds after energizing the wiper relay ON/OFF relay.

POSSIBLE CAUSES
- Wiper park switch operation
- Wiper park switch sense circuit shorted to voltage
- Wiper park switch sense circuit open
- Wiper park switch sense circuit shorted to ground
- Ground circuit open
- Fused ignition switch output RUN/ACC circuit open
- Wiper motor operation
- BCM
