Front Wiper Park Switch CKT Open

NAME OF CODE
Front Wiper Park Switch Ckt Open

WHEN MONITORED
With the ignition in the run or accessory position and battery voltage above 10 volts and wiper motor turned on.

SET CONDITION
The BCM, while monitoring the dwell switch, cannot determine when the wiper has left or returned to the park position.

THEORY OF OPERATION
The BCM interfaces with the front wiper motor and performs wiper functions based upon the input voltage from the multi-function switch. The BCM drives the wiper motor throughout the entire wiper cycle. The BCM, while monitoring the dwell switch, can determine when the wiper has left the park switch and when it returns. When it fails to receive that information, it sets this code.

The wiper will run in low speed only and stop whenever the switch is shut off.

POSSIBLE CAUSES
- Open wire
- Wiper motor
- Body Control module
