FRONT FOG LAMP SYSTEM
System Diagram
INFOID:0000000001099328
System Description
INFOID:0000000001099329
OUTLINE
Front fog lamp is controlled by combination switch reading function and front fog lamp control function of BCM,
and relay control function of IPDM E/R.
FRONT FOG LAMP OPERATION
• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the front fog lights request signal to IPDM E/R and the combination meter with CAN commu-
nication according to the front fog lamp ON condition.
Front fog lamp ON condition
- Front fog lamp switch ON
- Lighting switch 1ST, 2ND, or AUTO (ignition switch ON)
• IPDM E/R turns the integrated front fog lamp relay ON, and turns the front fog lamp ON according to the
front fog lights request signal.
• Combination meter turns the front fog lamp indicator lamp ON according to the front fog lights request signal.

Part
Description
BCM
• Detects each switch condition by the combination switch reading function.
• Judges the front fog lamp ON/OFF status according to the vehicle condition.
- Requests the front fog lamp relay ON to IPDM E/R (with CAN communication).
- Requests the front fog lamp indicator lamp ON to the combination meter (with CAN
communication).
IPDM E/R
Controls the integrated relay and supplies voltage to the load according to the request
from BCM (with CAN communication).
Combination switch

.
Combination meter
(Front fog lamp indicator lamp)
Turns the front fog lamp indicator lamp ON according to the request from BCM.

TURN SIGNAL AND HAZARD WARNING LAMP SYSTEM
System Diagram
INFOID:0000000001099332
System Description
INFOID:0000000001099333
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 OPERATION
• BCM transmits the turn signal indicator lamp signal to the combination meter with 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 signal indicator lamp signal.
3-TIME FLASHER FUNCTION
By a short touch of the turn signal lever, BCM flashes 3 times the turn signal lamps in the selected direction.
HIGH FLASHER OPERATION (FAIL-SAFE)
• BCM detects the turn signal lamp circuit status from the terminal voltage.
• 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
.
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).
