Relay Control Module Input Test
Relay Control Module Input Test1. Remove the under-hood fuse/relay box under cover.
2. Disconnect the 10P connector from the under-hood fuse/relay box.
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 the 10P connector from the under-dash 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.
