Wiper Control Module: Testing and Inspection

Control Circuit Input Test

1. Remove the gauge assembly.




2. Disconnect the 22P connector from the gauge assembly.
3. Inspect the connector and socket terminals to be sure they are making good contact.

- If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 4.




4. Reconnect the connector, and make these input tests at the connector.

- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, replace the printed circuit board in the gauge assembly.
