INSPECTION PROCEDURE M-2: The front and rear room lamp do not illuminate or extinguish
normally. <Vehicles with keyless entry system>

CAUTION

Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM
The ETACS-ECU operates this function in
accordance with the input signals below.

•

Ignition switch (IG1)

•

Key reminder switch

•

All of the door switches

•

Driver's door lock actuator

•

Interior lamp loaded signal

If this function does not work normally, these input
signal circuit(s), the interior lamp
