PARKING, LICENSE PLATE AND TAIL LAMPS SYSTEM
System DiagramINFOID:0000000003773539
System DescriptionINFOID:0000000003773540
OUTLINE
Parking, license plate and tail lamps are controlled by combination switch reading function and headlamp con-
trol function of BCM, and relay control function of IPDM E/R.
PARKING, LICENSE PLATE 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 and tail lamps.
Parking, license plate and tail lamps ON condition
- Lighting switch 1ST
- Lighting switch 2ND
- Lighting switch AUTO (auto light function ON judgment)
 IPDM E/R turns the integrated tail lamp relay ON and turns the parking lamp, license plate 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.

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).

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.
 Combination meter turns the rear fog lamp indicator lamp ON according to the rear fog lamp status signal.

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.
