CHECK HARNESS BETWEEN ROOM LIGHT AND KEYLESS ENTRY CONTROL MODULE (MODEL WITHOUT DOUBLE LOCK) OR DOUBLE LOCK UNIT (MODEL WITH DOUBLE LOCK).

1) Disconnect the keyless entry control module or double lock unit harness connector and room light harness connector.

2) Measure the resistance between the keyless entry control module or double lock unit harness connector terminal and room light harness connector terminal.

Connector & terminal

Model without double lock:

(B176) No. 11 — (R52) No. 2:

Model with double lock:

(B325) No. 1 — (R52) No. 2:

QUESTION

Is the resistance less than 10 Ω?

Yes No

The room light operation circuit is OK.

Check the harness for open circuits or shorts between the keyless entry control module (model without double lock) or double lock unit (model with double lock) and the room light.
