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.
With the connectors still disconnected, make these input tests at the connector. See Fig 3.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 5.

Connect the connectors to the gauge assembly and make these input tests at the connector. See Fig 4.
- 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.
