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 (front side marker) lamp, tail lamp, license plate lamp, rear side marker lamp and
front fog lamp

EXTERIOR LAMP BATTERY SAVER ACTIVATION

BCM activates the timer and turns the exterior lamp OFF 45 seconds after the ignition switch is turned from
ON 

→

 OFF with the exterior lamps ON.

• 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 

→

 1ST or 2ND with the exterior lamp

OFF.

Part

Description

BCM

• Detects each switch condition by the combination switch reading function.
• Activates the battery saver to turn the exterior lamps OFF according to the vehicle 

condition.

- Requests each relay OFF to IPDM E/R (with CAN communication). 

IPDM E/R

Controls the integrated relay according to the request from BCM (with CAN communi-
cation).

Combination switch
