Wiper and Washer Systems: Testing and Inspection

The complexity of the electronics involved with the Wipers and washers system preclude the use of workshop general electrical test equipment. Therefore, reference should be made to the PDU User Guide for detailed instructions on testing the wipers and washers.

The PDU systematically tests and analyses all functions of the wipers and washers system.

Where a fault involving the wipers and washers system is indicated by the PDU, some basic diagnostic methods may be necessary to confirm that connections are good and that the wiring is not damaged, before installing new components.

For further information regarding trouble codes for this system, please refer to Body Control Systems.
