FRONT FOG LAMP SYSTEM

System Diagram

INFOID:0000000000955380

System Description

INFOID:0000000000955381

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 and the combination meter with CAN commu-

nication according to the front fog lamp ON condition.

Front fog lamp ON condition

- Front fog lamp switch ON
- Lighting switch 1ST, 2ND, or AUTO (ignition switch 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.

• Combination meter turns the front fog lamp indicator lamp ON according to the front fog lights request signal.

Description

BCM

• Detects each switch condition by the combination switch reading function.
• Judges the front fog lamp ON/OFF status according to the vehicle condition.
- Requests the front fog lamp relay ON to IPDM E/R (with CAN communication).
- Requests the front fog lamp indicator lamp ON to the combination meter (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).

HEADLAMP AIMING CONTROL SYSTEM (AUTO)

System Diagram

INFOID:0000000000955384

System Description

INFOID:0000000000955385

OUTLINE

• Headlamp aiming control system is controlled by auto levelizer control unit.
• Auto levelizer control unit controls the headlamp light axis height appropriately depending on the vehicle rear

height.

• Auto levelizer control unit detects the vehicle condition necessary for the aiming motor control with the fol-

lowing signals.

- Sensor lever signal (detected by the sensor lever)
- Tail lamp signal (inputted from IPDM E/R)
- Vehicle speed signal (8-pulse) (inputted from combination meter)

HEADLAMP AUTO AIMING OPERATION

• Auto levelizer control unit calculates vehicle pitch angle from sensor lever signal and determines the neces-

sary correction to compensate the deviation from standard light axis position.

• Auto levelizer control unit outputs aiming motor drive signal when operating conditions are satisfied.

Operating condition

- Headlamp (LO) ON
- Tail lamp ON
• Auto levelizer control unit changes the aiming motor drive signal when any of the correcting condition is

detected. Output is maintained if other condition is detected.

Correcting condition

- Headlamp (LO) is turned ON.
- Vehicle posture becomes stable after the vehicle posture change is detected with the headlamp (LO) ON

and the vehicle stopped.

- Vehicle speed is maintained with the headlamp (LO) ON and the vehicle driven.

CAUTION:

Adjusted axis position may differ from the preset position although the headlamp auto aiming acti-
vates properly when the suspension is replaced or worn.
