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
appropriate 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. Reconnect the connectors to the under-dash fuse/relay box, 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, the MICU must be faulty; replace the
under-dash fuse/relay box.
