TURN SIGNAL AND HAZARD WARNING LA MP SYSTEM : System Description
INFOID:0000000006213902
OUTLINE
Turn signal and the hazard warning lamp is controlled by combination switch reading function, flasher control
function and auto hazard function of BCM.
TURN SIGNAL LAMP OPERATION
BCM detects the combination switch conditi on by the combination switch reading function.
BCM supplies voltage to the right (left) turn signal la mp circuit when the ignition switch is turned ON and the
turn signal switch is in the right (left) position. BCM blinks the turn signal lamp.
HAZARD WARNING LAMP OPERATION
BCM supplies voltage to both turn signal lamp circuit when the hazard switch is turned ON. BCM blinks the
hazard warning lamp.
TURN SIGNAL INDICATOR LAMP AND TURN SIGNAL SOUND OPERATION
BCM transmits the turn indicator signal to the comb ination meter via CAN communication while the turn sig-
nal lamp and the hazard warning lamp operating.
Combination meter outputs the turn signal sound with the integrated buzzer while blinking the turn signal
indicator lamp according to the turn indicator signal.
HIGH FLASHER OPERATION
BCM detects the turn signal lamp ci rcuit status from the current value.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn sig-
nal lamp operating.
NOTE:
The blinking speed is normal while operating the hazard warning lamp.
