Relay Control Module Input Test

Relay Control Module Input Test

1. 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. With the connector still disconnected, 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 module must be faulty, replace the under-hood fuse/relay box.
