OUTLINE

Rear fog lamp is controlled with the combination switch reading function and the rear fog lamp control function
of BCM. 

REAR FOG LAMP OPERATION

• BCM detects the condition of the combination switch by the combination switch reading function.
• BCM supplies voltage to rear fog lamp according to the rear fog lamp ON condition.

Rear fog lamp ON condition

- Rear fog lamp switch signal is input with front fog lamp ON and rear fog lamp OFF

Rear fog lamp OFF condition

- Rear fog lamp switch signal is input with rear fog lamp ON
- Front fog lamp OFF
• BCM transmits the rear fog lamp status signal to the combination meter with CAN communication. 
• Combination meter turns the rear fog lamp indicator lamp ON according to the rear fog lamp status signal.

Description

BCM

• Detects each switch condition by the combination switch reading function. 
• Judges that the rear fog lamp is turned ON according to the vehicle status
- Supplies voltage to the rear fog lamp
- Requests the rear fog lamp indicator lamp ON to the combination meter (with CAN 

communication).
