System Description

INFOID:0000000009722885

OUTLINE

Parking, license plate, side marker and tail lamps are controlled by combination switch reading function and
headlamp control function of BCM, and relay control function of IPDM E/R.

PARKING, LICENSE PLATE, SIDE MARKER AND TAIL LAMPS OPERATION 

• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the position light request signal to IPDM E/R and the combination meter with CAN communi-

cation according to the ON/OFF condition of the parking, license plate, side marker and tail lamps.

Parking, license plate, side marker and tail lamps ON condition

- Lighting switch 1ST
- Lighting switch 2ND
• IPDM E/R turns the integrated tail lamp relay ON and turns the parking lamp, license plate, side marker and

tail lamps ON according to the position light request signal.

• Combination meter turns the tail lamp indicator lamp ON according to the position light request signal.

Description

BCM

• Detects each switch condition by the combination switch reading function.
• Judges the ON/OFF status of the parking, license plate and tail lamps according to 

the vehicle condition.

- Requests the tail lamp relay ON to IPDM E/R (with CAN communication). 
- Requests the tail lamp indicator lamp ON to the combination meter (with CAN com-

munication).

IPDM E/R

Controls the integrated relay and supplies voltage to the load according to the request 
from BCM (with CAN communication).

Combination switch
(Lighting & turn signal switch)

EXTERIOR LAMP BATTERY SAVER SYSTEM

System Diagram

INFOID:0000000009722888

System Description

INFOID:0000000009722889

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, side marker lamp, tail lamp, license plate lamp and front 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 

→

 1ST or 2ND with the exterior lamp

OFF.
