Relay Control Module Input Test
Relay Control Module Input TestNOTE: Check the No. 22 (120 A), No. 23 (50 A), NO. 15 (40 A) fuse in the under-hood fuse/relay box before troubleshooting.
1. Before troubleshooting the multiplex integrated control system, troubleshoot the B-CAN System Diagnosis Test mode A.
2. Turn the ignition switch OFF.
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 the 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 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, the relay control module must be faulty, replace the under-hood fuse/relay box.
