Correcting condition (when any of the following conditions are satisfied)

- Ignition switch ON
- Headlamp (LO) is turned ON.
- Vehicle posture becomes stable after the vehicle posture change is detected with the headlamp (LO) ON

and the vehicle stopped.

- Vehicle speed is maintained with the headlamp (LO) ON and the vehicle driven.
NOTE:
Adjusted axis position may differ from the preset position although the headlamp auto aiming activates prop-
erly when the suspension is replaced or worn.

TURN SIGNAL AND HAZARD WARNING LAMP SYSTEM : System Description

INFOID:0000000010788758

SYSTEM DIAGRAM

OUTLINE

Turn signal lamp and 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 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 circuits when the hazard switch is 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 using CAN communication while the turn

signal 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.

3-TIME FLASHER FUNCTION

• By a short touch of the turn signal lever, BCM blinks the turn signal lamps 3 times in the selected direction.
• Cancels the operation when short touch of the turn signal lever in the reverse direction during the 3-time

flasher function operation.

NOTE:
ON/OFF of 3-time flasher function can be changed using CONSULT. Refer to 

EXL-57, "FLASHER : CONSULT

Function (BCM - FLASHER) (LED Headlamp)"

.

HIGH FLASHER OPERATION

• BCM detects the turn signal lamp circuit 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.

AUTO HAZARD FUNCTION

• Air bag diagnosis sensor unit transmits car crash information signal to BCM via CAN communication, when

air bag diagnosis sensor unit detects strong impact to the vehicle body while ignition switch is ON.

• When car crash information signal received from air bag diagnosis sensor unit is detected, BCM supplies

voltage to each turn signal lamp system and hazard lamp blinks.
