• 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 switch ON with any of following condition.

- Lighting switch 2ND
- Lighting switch 1ST, and front fog lamp switch ON
• BCM transmits the rear fog lamp status signal to the combination meter with CAN communication.

System Description

INFOID:0000000003894302

OUTLINE

• Exterior lamp battery saver system is controlled by each function of BCM and IPDM E/R.

Control by BCM

- Combination switch reading function
- Headlamp control function
- Exterior lamp battery saver function

Control by IPDM E/R

- Relay control function
• BCM turns the exterior lamp* OFF after a period of time to prevent the battery from over-discharge when the

ignition switch is turned OFF with the exterior lamp ON.

*: Headlamp (LO/HI), parking lamp, tail lamp, license plate lamp, front fog lamp and rear fog lamp.

EXTERIOR LAMP BATTERY SAVER ACTIVATION

BCM activates the timer and turns the exterior lamp OFF 5 minutes after the ignition switch is turned from ON

→

 OFF with the exterior lamps ON. 

NOTE:
• Headlamp control function turns the exterior lamps ON normally when the ignition switch is turned ACC or

the engine started (both before and after the exterior lamp battery saver is turned OFF).

• The timer starts at the time that the lighting switch is turned from OFF
