TURN SIGNAL AND HAZARD WARNING LAMP SYSTEM

System Diagram

INFOID:0000000005244676

System Description

INFOID:0000000005244677

OUTLINE

Turn signal 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 signal indicator lamp signal to the combination meter (through the unified meter and

A/C amp.) with CAN communication while the turn signal 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 signal indicator lamp 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.

Description

BCM

• Detects each switch condition by the combination switch reading function.
• Judges the blinks of the turn signal lamp and the hazard warning lamp from each 

switch status. The applicable turn signal lamp blinks.
Requests the turn signal indicator lamp blink to the combination meter (with CAN 
communication).

System Description

INFOID:0000000005244681

OUTLINE

Parking, license plate, side marker and tail lamps are controlled by combination switch reading function and
headlamp control function of BCM, and relay control function of IPDM E/R.

PARKING, LICENSE PLATE, SIDE MARKER AND TAIL LAMPS OPERATION

• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the position light request signal to IPDM E/R with CAN communication according to the ON/

OFF condition of the parking, license plate, side marker and tail lamps.

Parking, license plate, side marker and tail lamps ON condition

- Lighting switch 1ST
- Lighting switch 2ND
- Lighting switch AUTO, and the auto light function ON judgment
• IPDM E/R turns the integrated tail lamp relay ON and turns the parking lamp, license plate, side marker and

tail lamps ON according to the position light request signal.

• Combination meter turns the tail lamp indicator lamp ON according to the position light request signal.
