TURN SIGNAL AND HAZARD WARNING LAMP SYSTEM

System Diagram

INFOID:0000000003894289

System Description

INFOID:0000000003894290

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.

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).

Combination switch
(Lighting & turn signal switch)

Refer to 

BCS-8, "System Diagram"

.

Hazard switch

Inputs the hazard switch ON/OFF signal to BCM.

Combination meter
(Turn signal indicator lamp & buzzer)

Blinks the turn signal indicator lamp and outputs the turn signal operating sound with 
integrated buzzer according to the request from BCM (with CAN communication).

INFOID:0000000003894293

System Description

INFOID:0000000003894294

OUTLINE

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

PARKING, LICENSE PLATE 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 and the combination meter with CAN communi-

cation according to the ON/OFF condition of the parking, license plate and tail lamps.

Parking, license plate and tail lamps ON condition

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

Description

BCM

• Detects each switch condition by the combination switch reading function.
• Judges the ON/OFF status of the parking, license plate and tail lamps according to 

the vehicle condition.

- Requests the tail lamp relay ON to IPDM E/R (with CAN communication). 
- Requests the tail lamp indicator lamp ON to the combination meter (with CAN com-

munication).

IPDM E/R

Controls the integrated relay and supplies voltage to the load according to the request 
from BCM (with CAN communication).
