Unit Description
Combination meter Receives key warning signal from BCM via CAN communication line and sounds the buzzer.
BCM Judges the key warning condition using the door switch signal received from the front door switch
LH, and the key switch signal received from the key switch and ignition knob switch. It then transmits
a buzzer output signal to the combination meter via CAN communication line if necessary.
Front door switch LH Transmits door switch signal to BCM.
Key switch and ignition knob
switch Transmits key switch signal to BCM.
