1.

VEHICLE CONDITION CHECK

1.

Park the vehicle in the straight-forward position.

2.

Unload the vehicle (no passenger aboard).

>> GO TO 2.

2.

SENSOR INITIALIZE

CONSULT-III WORK SUPPORT

1.

Turn the headlamp (LO) ON.

2.

Connect the CONSULT-III.

3.

Select "SENSOR INITIALIZE" of HEADLAMP LEVELIZER work support item.

4.

Select "START".

5.

When "INITIALIZE COMPLETE", select "END".

CAUTION:

If "INITIALIZE NOT DONE" is indicated, auto levelizer control unit detects that the sensor lever sig-
nal changes. The sensor initialize is cancelled. In this case, turn the ignition switch OFF to prevent
the vehicle from the height change. Perform the sensor initialize again.

Is the sensor initialize completed?

YES

>> GO TO 3.

NO

>> Perform the sensor initialize again.

3.

SELF-DIAGNOSIS RESULT CHECK

Perform the self-diagnosis with CONSULT-III. Check that any DTC is not detected.

Is any DTC detected?

YES

>> GO TO 2.

NO

>> Sensor initialize completed.

HEADLAMP SYSTEM

System Diagram

INFOID:0000000000955372

System Description

INFOID:0000000000955373

OUTLINE

Headlamp is controlled by combination switch reading function and headlamp control function of BCM, and
relay control function of IPDM E/R.

HEADLAMP (LO) OPERATION 

• BCM detects the combination switch condition with the combination switch reading function.
• BCM transmits the low beam request signal to IPDM E/R with CAN communication according to the head-

lamp (LO) ON condition.

Headlamp (LO) ON condition

- Lighting switch 2ND
- Lighting switch AUTO, and the auto light function ON judgment (With auto light system)
- Daytime running light ON judgment (With daytime running light system)
• IPDM E/R turns the integrated headlamp low relay ON, and turns the headlamp ON according to the low

beam request signal.

HEADLAMP (HI) OPERATION

• BCM transmits the high beam request signal to IPDM E/R and the combination meter with CAN communica-

tion according to the headlamp (HI) ON condition. 

Headlamp (HI) ON condition

- Lighting switch HI with the lighting switch 2ND or AUTO (auto light function ON judgment)
- Lighting switch PASS
• Combination meter turns the high beam indicator lamp ON according to the high beam request signal. 
• IPDM E/R turns the integrated headlamp high relay ON, and turns the headlamp ON according to the high

beam request signal.

FOLLOW ME HOME FUNCTION

When the driver is moving to the house entrance from the own vehicle, headlamp is kept still ON by the follow
me home function of BCM.
• When BCM detects the input of lighting switch PASS with all of following condition, it transmits the low beam

request signal for a period of time to IPDM E/R through CAN communication.

• IPDM E/R turns the integrated headlamp low relay ON, and turns the headlamp ON according to the low

beam request signal.

- Ignition switch OFF
- Lighting switch OFF or AUTO

Part

Description

BCM

• Detects each switch condition by the combination switch reading function.
• Judges that the headlamp is turned ON according to the vehicle condition. 
- Requests the headlamp relay (HI/LO) ON to IPDM E/R (with CAN communication). 
- Requests the high beam 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).

Combination switch
(Lighting & turn signal switch)

Refer to 

BCS-9, "System Diagram"

.

Combination meter
(High beam indicator lamp)

Turns the high beam indicator lamp ON according to the request from BCM (with CAN 
communication).
