Control Unit Input Test

NOTE: Before testing, troubleshoot the B-CAN System Diagnosis Test Mode A.

MICU

1. Turn the ignition switch OFF.

2. Remove the left kick panel.

3. Disconnect the under-dash fuse/relay box connectors.

NOTE: All connector views are wire side of female terminals.

4. 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 5.

5. Reconnect the connectors, then 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, go to step 6.

Gauge Control Module

6. Turn the ignition switch OFF.

7. Remove the gauge control module.

8. Disconnect the gauge control module 36P connector.

9. 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 10.

10. With the connectors still disconnected, make these input tests at all connectors.

• If any test indicates a problem, find and correct the cause, then recheck. the system.
• If the input tests prove OK, go to step 11.

11. Reconnect the gauge control module 36P connector, then 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, go to step 12.

12. Do the Gauge Self-diagnostic Function Procedure.

• If the beeper sounds and the seat belt reminder light flashes, go to step 13.
• If the beeper does not sound or the seat belt reminder light does not flash, replace the gauge control module.

13. Substitute a known-good gauge control module, and recheck the system.

• If the symptom is gone, the gauge control module is faulty; replace it.
• If the symptom is still present, the MICU is faulty; replace the under-dash fuse/relay box.
