AUTO LIGHT SYSTEM

NOTE:
As to ON/OFF timing, the sensitivity depends on settings. The settings can be changed with CONSULT. Refer
to 

EXL-21, "HEADLAMP : CONSULT Function (BCM - HEAD LAMP)"

.

WIPER LINKED AUTO LIGHTING FUNCTION

BCM turns the exterior lamp ON when detecting 4 operations of the front wiper work the light switch in AUTO
position.
NOTE:
BCM turns OFF the headlamps 3 seconds after the front wiper switch is turned from HI

⇒

OFF.

DELAY TIMER FUNCTION

BCM turns the exterior lamp OFF depending on the vehicle condition with the auto light function when the igni-
tion switch is turned OFF.
• Turns the exterior lamp OFF 5 minutes after detecting that any door opens (Door switch ON).
• Turns the exterior lamp OFF a certain period of time* after closing all doors (Door switch ON

→

OFF).

• Turns the exterior lamp OFF with the ignition switch ACC or the light switch OFF.
*: The preset time is 45 seconds. The timer operating time can be set by CONSULT. Refer to 

EXL-21, "HEAD-

LAMP : CONSULT Function (BCM - HEAD LAMP)"

.

NOTE:
When any position other than the light switch AUTO is set, the auto light system function switches to the exte-
rior lamp battery saver function.

Description

BCM

• Detects each switch condition by the combination switch reading function.
• Judges the outside brightness from the optical sensor signal.
• Judges the OFF timing according to the vehicle condition.
• Judges the ON/OFF status of the exterior lamp and each illumination according to the 

outside brightness and the vehicle condition.

- Requests ON/OFF of each relay 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).

FRONT FOG LAMP SYSTEM

System Diagram

INFOID:0000000009945110

System Description

INFOID:0000000009945111

OUTLINE

Front fog lamp is controlled by combination switch reading function and front fog lamp control function of BCM,
and relay control function of IPDM E/R.

FRONT FOG LAMP OPERATION 

• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the front fog lights request signal to IPDM E/R with CAN communication according to the

front fog lamp ON condition.

Front fog lamp ON condition

- Front fog lamp switch ON and any of the followings. (except for the high beam ON)
• Lighting switch 2ND
• Lighting switch AUTO and the ignition switch ON

NOTE:
Headlamp, front fog lamp, parking lamp, licence plate lamp, side marker lamp and tail lamp are turned ON.

• IPDM E/R turns the integrated front fog lamp relay ON, and turns the front fog lamp ON according to the

front fog lights request signal.
