System Description
INFOID:0000000003135281
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 with CAN communication 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
- Lighting switch AUTO, and the auto light function ON judgment (with auto light system)
• IPDM E/R turns the integrated tail lamp relay ON and turns the parking lamp, the 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
• Judges each switch condition by the combination switch reading function.
• Judges the ON/OFF status of the clearance, license plate, side marker and tail
lamps according to the vehicle condition. Requests the tail lamp relay ON to IPDM
E/R (with CAN communication).
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)
Refer to
.
Combination meter
(Tail lamp indicator lamp)
Turns the tail lamp indicator lamp ON according to the request from BCM [with CAN

System Description
INFOID:0000000003135285
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, side marker lamp, license plate lamp and front fog lamp
NOTE:
When the lighting switch is turned AUTO, the exterior lamp battery saver switches to the auto light system.
Refer to
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
