MICU Input Test

1. Turn the ignition switch to LOCK (0).
2. Remove the left kick panel.
3. Disconnect driver's under-dash fuse/relay box connectors E, F, R, and S.

NOTE: All connector views are shown from wire side of female terminals.






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 under-dash fuse/relay box connectors and MICU connectors 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, go to step 6.






6. Reconnect the under-dash fuse/relay box connectors and MICU connectors, then 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 MICU must be faulty; replace the under-dash fuse/relay box assembly.
