Relay Control Module Input Test

Relay Control Module Input Test

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

1. Turn the ignition switch ON (II), and remove the under-hood fuse/relay box undercover.
2. Disconnect under-hood fuse/relay box connector J (10P).






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 look OK, go to step 4.

4. 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, go to step 5.






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