Entry Lights Control System (MICU) Input Test

Entry Lights Control System (MICU) Input Test

NOTE: Before testing, check the No. 1 (15 A), No. 22 (7.5 A), and No. 60 (IGN) (50 A) fuses in the under-dash fuse/relay box.

1. Turn the ignition switch to LOCK (0).

2. Remove the fuse access panel Fuse Access Panel Removal / Installation, and remove the driver's dashboard lower cover Driver's Dashboard Lower Cover Removal / Installation.

3. Disconnect the under-dash fuse/relay box connectors C, E, G, K, M, N, Q, and W.

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. Reconnect the connectors to the under-dash fuse/relay box, and do the following input tests:

- 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:
