Relay Control Module Input Test
Relay Control Module Input TestNOTE: Before testing the relay control module, troubleshoot the multiplex integrated control unit first, using B-CAN System Diagnosis Test Mode A.
1. Turn the ignition switch to LOCK (0).
2. Remove the under-hood fuse/relay box.
3. Disconnect under-hood fuse/relay box connectors D (10P) and E (14P).
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 look OK, go to step 5.
5. With the connectors still disconnected, make these input tests at the connectors.
- 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.
6. Reconnect the connectors, and make these input tests at the connectors.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, replace the relay control module.
