STOP LAMP SYSTEM : System Description

INFOID:0000000010469901

SYSTEM DIAGRAM

OUTLINE

Stop lamp and high-mounted stop lamp is controlled by combination switch reading function and the stop lamp
and high-mounted stop lamp control function of BCM, and forward emergency braking function of ABS actua-
tor and electric unit (control unit).

STOP LAMP AND HIGH-MOUNTED STOP LAMP OPERATION

• BCM detects the brake pedal position status from stop lamp switch.
• BCM supplies voltage to stop lamp and high-mounted stop lamp according to the stop lamp and high-

mounted stop lamp ON condition.

Stop lamp and high-mounted stop lamp ON condition

- Brake pedal is depressed

FORWARD EMERGENCY BRAKING FUNCTION

• When the Forward Emergency Braking operates, the ABS actuator and electric unit (control unit) transmits

the stop lamp request signal to BCM via CAN communication. (For details about the Forward Emergency
Braking, refer to

BRC-150, "System Description"

• When BCM receives the stop lamp request signal from the ABS actuator and electric unit (control unit), it

supplies power to the stop lamp and high-mounted stop lamp systems, turning ON the stop lamp and high-
mounted stop lamp.

OUTLINE

Front fog lamp is controlled by combination switch reading function and front fog lamp control function of BCM,
and smart FET 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 light request signal to IPDM E/R and the combination meter via CAN communi-

cation according to the front fog lamp ON condition.

Front fog lamp ON condition (when any of the following conditions are satisfied) (without rear fog lamp)

- Lighting switch 1ST with the front fog lamp switch ON
- Lighting switch 2ND with the front fog lamp switch ON
- Lighting switch AUTO with the front fog lamp switch ON (Only when the illumination judgment by auto light

system is ON. For details, refer to

EXL-192, "AUTO LIGHT SYSTEM : System Description"

Front fog lamp ON condition (with rear fog lamp)

- Front fog lamp switch is turned from OFF to ON, and any of the following conditions are satisfied.
• Lighting switch 1ST
• Lighting switch 2ND
• Lighting switch AUTO (Only when the illumination judgment by auto light system is ON. For details, refer to

EXL-192, "AUTO LIGHT SYSTEM : System Description"

• IPDM E/R turns the integrated smart FET ON, and turns the front fog lamp ON according to the front fog light

request signal.

• Combination meter turns the front fog lamp indicator lamp ON according to the front fog light request signal.
