B232E-00-REAR WASHER SWITCH STUCK

For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation

The Wiper/Washer Switch is integral to the Multifunction Switch. The Multifunction Switch is connected to the left side of the Clockspring/SAS. The Multifunction switch provides the primary controls for the front wiper/rear wiper/washer systems, turn signals and for headlamp high beam selection. The Multifunction Switch communicates with the Steering Angle Sensor (SAS) (integral to the Steering Column Control Module) via the LIN Bus. The SAS then converts this data to a CAN Bus signal and broadcasts the message to the corresponding module on the bus. Multifunction Switch - Operation.

- When Monitored:
With the ignition on.

- Set Condition:
The Steering Column Control Module (SCCM) detects the Rear Washer Switch is active for greater than 20 seconds.





CHECK FOR AN ACTIVE DTC

NOTE: Before proceeding with the diagnostic procedure, verify that the connections are properly made, seated and verify proper pin terminal tension. A loose connection at any of the SCCM connectors may cause the DTC to set.

1. Turn the ignition on.
2. Actuate the Rear Washer Switch twice. (The scan tool can be used to monitor switch status. Status can be viewed in the SCCM data display.)
3. With the scan tool, read DTCs.

Does the scan tool display this DTC as active?

Yes

- Replace the Multifunction Switch. Multifunction Switch - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
