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.
