Relay Control Module Input Test

Relay Control Module Input Test

NOTE: Check the No. 22 (120 A), No. 23 (60 A), No. 15 (40 A) fuse in the under-hood fuse/relay box before troubleshooting.

1. Before troubleshooting the multiplex integrated control system, do B-CAN System Diagnosis Test Mode A Troubleshooting - B-CAN System Diagnosis Test Mode A.

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

3. Check the No. 7 (7.5 A) fuse in the under-hood fuse/relay box.

4. Remove the under-hood fuse/relay box under cover.

5. Disconnect under-hood fuse/relay box connector J (10P).





6. 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 7.

7. Reconnect the connector to the under-hood fuse/relay box, and do the following input tests:

- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the relay control module must be faulty, replace the under-hood fuse/relay box.
