FRONT CAMERA UNIT TEMPORARY OPERATION CANCELLATION

• Temporary disabled status at high temperature
- If the vehicle is parked in direct sunlight under high temperature conditions, the system may be deactivated

automatically. And the system malfunction in information display.

[LED HEADLAMP]

SYSTEM

- When interior temperature is reduced, the system will resume operation automatically.
• When vehicle front identification is difficult
- When vehicle front identification is difficult due to soiling of windshield glass and strong light shining from the

front, operation may be canceled temporarily. At this time, a warning is displayed on the vehicle information
display in the combination meter.

- Normal operation recovers when conditions improve.

DAYTIME RUNNING LIGHT SYSTEM

DAYTIME RUNNING LIGHT SYSTEM : System Description

INFOID:0000000010788752

SYSTEM DIAGRAM

OUTLINE

Daytime running light is controlled by daytime running light control function and combination switch reading
function of BCM, and smart FET control function of IPDM E/R.

DAYTIME RUNNING LIGHT OPERATION 

• BCM detects the combination switch condition by the combination switch reading function.
• BCM detects vehicle condition depending on the engine status signal and Stop/Start status signal* (received

from ECM via CAN communication).

• BCM transmits the daytime running light request signal to IPDM E/R via CAN communication according to

the daytime running light ON condition.

Daytime running light ON condition

- Engine running and any following conditions are satisfied.
• Lighting switch OFF
• Lighting switch AUTO (Only when the illumination judgment by auto light system is OFF. For details, refer to

EXL-24, "AUTO LIGHT SYSTEM : System Description"

.)

• IPDM E/R turns the integrated smart FET ON, and turns the daytime running light ON according to the day-

time running light request signal.

NOTE:
When the engine is stopped by the Stop/Start system, the operation of daytime running light system is not can-
celed.*
*: With Stop/Start system

FAIL-SAFE CONTROL BY DTC

IPDM E/R performs fail-safe control when any DTC are detected.

CAN COMMUNICATION CONTROL

When CAN communication with BCM is impossible, IPDM E/R performs fail-safe control. After CAN communi-
cation recovers normally, it also returns to normal control.

If No CAN Communication Is Available With BCM

HEADLAMP AIMING CONTROL SYSTEM (AUTO)

HEADLAMP AIMING CONTROL SYSTEM (AUTO) : System Description

INFOID:0000000010788755

SYSTEM DIAGRAM

OUTLINE

• Headlamp aiming control system is controlled by IPDM E/R.
• IPDM E/R controls the headlamp light axis height appropriately depending on the vehicle front height (3-row

seat models) and vehicle rear height.

• IPDM E/R detects the vehicle condition necessary for the headlamp aiming motor control with the following

signals.

- Front height sensor signal [inputted from front height sensor (3-row seat models)]
- Rear height sensor signal (inputted from rear height sensor)
- Low beam request signal (received from BCM via CAN communication)
- Vehicle speed signal (received from combination meter via CAN communication)

HEADLAMP AUTO AIMING OPERATION

• IPDM E/R calculates vehicle pitch angle from front height sensor (3-row seat models) and rear height sensor

signal and determines the necessary correction to compensate the deviation from standard light axis posi-
tion.

• IPDM E/R outputs aiming motor drive signal when operating conditions are satisfied.

Operating condition (when all of the following conditions are satisfied)

- Ignition switch ON
- Headlamp (LO) ON
• IPDM E/R changes the aiming motor drive signal when any of the correcting condition is detected. Output is

maintained if other condition is detected.
