Part 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/RControls the integrated relay and supplies voltage to the load according to the request
from BCM (with CAN communication).
Combination switch
(Lighting & turn signal switch)Refer to BCS-8, "
System Diagram".
Combination meter
(Tail lamp indicator lamp)Turns the tail lamp indicator lamp ON according to the request from BCM (with CAN
communication).

EXTERIOR LAMP BATTERY SAVER SYSTEM
System DiagramINFOID:0000000003773543
System DescriptionINFOID:0000000003773544
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 → 1ST or 2ND with the exterior lamp
OFF.
