buzzer sounds twice and he answer-back function of the keyless
entry system is initialised.

INSPECTION PROCEDURE 2
All of the doors can be locked and unlocked using th
transmitter, but the room lamp or turn-signal lamp does
not flash or illuminate. (However, the room lamp oper-
ates normally when the doors are opened and closed.)Probable cause
If neither room lamp nor turn-signal lamp flash/illuminate, the
cause may be a malfunction of the ETACS-ECU or driver’s-side
door lock actuator.
If either room lamp or turn-signal lamp does not flash/illuminate,
the cause may be a malfunction of the room lamp circuit or turn-
signal lamp.•
Malfunction of ETACS-ECU
•
Malfunction of driver’s door lock actuator
•
Burnt turn-signal lamp bulb
