Gauge Control Module Unit Input Test

Gauge Control Module Input Test

1. Remove the gauge control module.
2. Disconnect connector A (30P) from the gauge control module.




3. Inspect the connector and socket terminals to be sure they are all 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 connector A to the gauge control module, 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 gauge control module.
