Entry Lights Control System (MICU) Input Test

NOTE: Before testing, check for No. 22 (7.5 A) fuse in the under-dash fuse/relay box.

Turn the ignition switch to LOCK (0).

RHD model: Remove the fuse lid panel , and remove the driver's dashboard lower cover.

LHD model: Remove the fuse lid panel.

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.
- The illustration shows the RHD models and the black portion shows the lock lever. The lock lever for LHD model is shown as the dashed lines.

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 .

With the connectors still disconnected, 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, go to Step 6 .

Reconnect the connectors to the under-dash fuse/relay box, and 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, replace the under dash fuse relay box.
