INSPECTION PROCEDURE FOR TROUBLE SYMPTOMS
Inspection Procedure 1
The lighting monitor buzzer does not sound when the
ignition switch is turned to OFF position and the driver’s
side door is opened while the tail lamps or headlamps
illuminate.
When
the automatic headlamp switch-off function
operates, headlamps switch off after the buzzer sounds
for one second, and the buzzer ceases sounding.
Probable cause
The cause is probably a malfunction of the lighting switch input circuit system or
