DIAGNOSTIC PROCEDURES
The windshield wiper system operates in several modes:
- Low and high speed normal wipe
- Speed sensitive intermittent wipe
- Wipe after wash
- Pulse wipe
- Park (switch OFF)

The windshield wiper circuits are continuously monitored and controlled by the Body Control Module (BCM). If a problem occurs in the electronic components, wiring, switch (except integral motor park switch) and wiper motor a Diagnostic Trouble Code (DTC) will be stored in the BCM memory. DTC's can be retrieved using a DRB III� scan tool. Refer to the proper Body Diagnostic Procedures for DTC descriptions and retrieval information.

The windshield wiper park switch and circuit is monitored by the BCM. The park switch and circuit can be tested using the Wiper System Diagnosis table.
