Gauge Control Module Input Test

NOTE:

- Before testing, do the gauge control module self-diagnosis function, and make sure the B-CAN communication lines are OK.
- Before testing, troubleshoot the multiplex integrated control system first, using B-CAN System Diagnosis Test Mode A Troubleshooting - B-CAN System Diagnosis Test Mode A.

1. Turn the ignition switch to LOCK (0).

2. Remove the gauge control module, and disconnect the gauge control module 32P connector (A) from it.





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 are OK, go to step 4.

4. With the connector still disconnected, do the following input tests:

- If any test indicates a problem, find and correct the cause, then recheck the system.
- If the input test proves OK, go to step 5.





5. Reconnect the 32P connector to the gauge control module, and do the following input tests:

- If any test indicates a problem, find and correct the cause, then recheck the system.
- If the input test proves OK, the gauge control module must be faulty; replace it Service and Repair.
