TURN SIGNAL AND HAZARD WARNING LAMP SYSTEM
System DiagramINFOID:0000000003773535
System DescriptionINFOID:0000000003773536
OUTLINE
Turn signal lamp and the hazard warning lamp is controlled by combination switch reading function and the
flasher control function of BCM.
TURN SIGNAL LAMP OPERATION
 BCM detects the combination switch condition by the combination switch reading function.
 BCM supplies voltage to the right (left) turn signal lamp 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 combination meter with CAN communication while the turn sig-
nal lamp and the hazard warning lamp are 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 (FAIL-SAFE)
 BCM detects the turn signal lamp circuit status by the terminal 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.

TURN SIGNAL LAMP CIRCUIT
TURN SIGNAL LAMP CIRCUIT
DescriptionINFOID:0000000003773570
BCM performs the high flasher operation (fail-safe) if any bulb or harness of the turn signal lamp circuit is
open.
NOTE:
The turn signal lamp blinks at normal speed when using the hazard warning lamp.
Component Function CheckINFOID:0000000003773571
1.CHECK TURN SIGNAL LAMP
CONSULT-III ACTIVE TEST
1. Select “FLASHER” of BCM (FLASHER) active test item.
2. With operating the test items, check that the turn signal lamp is turned ON.
Is the turn signal lamp turned ON?
YES >> Turn signal lamp circuit is normal.
NO >> Refer to EXL-66, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000003773572
1.CHECK TURN SIGNAL LAMP BULB
Check the applicable lamp bulb.
Is the bulb normal?
YES >> GO TO 2.
NO >> Replace the bulb.
2.CHECK TURN SIGNAL LAMP OUTPUT VOLTAGE
1. Turn the ignition switch OFF.
2. Disconnect the front combination lamp connector, the door mirror connector or the rear combination lamp
connector.
3. Turn the ignition switch ON.
4. With operating the turn signal switch, check the voltage between the BCM harness connector and the
ground.LH : Turn signal lamps (LH) ON
