Instrument Panel Control Module: Testing and Inspection

Control Circuit Input Test

1. Remove the gauge assembly.




2. Disconnect the gauge assembly SOP connector A and 22P connector B.
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. Connect the connectors to the gauge assembly 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.
