LED HEADLAMP OPERATION INSPECTION 

Work Procedure

INFOID:0000000010338707

1.

CHECK START

1.

In the cool LED status (wait for more than 10 minutes after turning headlamp OFF), turn ON and turn OFF
headlamp for the several times. Check that headlamp operates normally each time.

2.

In the cool LED status, turn headlamp ON, wait until headlamp enters to the stable status (approximately
5 minutes after turning headlamp ON), and then check that headlamp operates normally without blinking
or flickering.

3.

In the warm LED status (turn headlamp ON for more than 15 minutes and wait for 1 minute after turning
OFF), turn ON and turn OFF headlamp for the several times. Check that headlamp operates normally
each time.

4.

Turn headlamp ON for approximately 30 minutes, and then check that headlamp operates normally with-
out difference in brightness between LH and RH, blinking or flickering.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Refer to 

EXL-145, "Symptom Table"

SENSOR INITIALIZE

SENSOR INITIALIZE

Description

INFOID:0000000010338722

Perform the sensor initialize when the following operation is performed.
• Replacing IPDM E/R
• Removing, installing or replacing height sensor
• Adjusting, removing, installing or replacing suspension components

Work Procedure

INFOID:0000000010338723

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

With CONSULT

1.

Turn ignition switch ON.

2.

Select “SENSOR INITIALIZE” in “Work Support” mode of “IPDM E/R” using CONSULT.

3.

Touch "Start".

4.

When "INITIALISE COMPLETE", touch "End".
NOTE:
If "INITIALISE NOT DONE" is indicated, IPDM E/R detects that the height sensor signal 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 DIAGNOSTIC RESULT CHECK

With CONSULT

1.

Select “Self Diagnostic Result” mode of “IPDM E/R” using CONSULT.

2.

Check DTC.

Is DTC detected?

YES

>> GO TO 2.

NO

>> WORK END

DTC Description

INFOID:0000000010452520

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector
• Front fog lamp LH bulb
• IPDM E/R

FAIL-SAFE

Shuts off the power supply to the front fog lamp LH power supply circuit until the front fog lamp ON conditions
are no longer satisfied.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

With CONSULT

1.

Turn ignition switch ON.

2.

Select “F FOG LH CIRC MALFUNCTN” in “Data Monitor” mode of “IPDM E/R” using CONSULT.

3.

Check the monitor status.

What is the monitor status?

“0”

>> GO TO 2.

“1”

>> A short circuit is detected multiple times in the front fog lamp LH power supply circuit, and damage

accumulates at the smart FET inside the IPDM E/R. For this reason, IPDM E/R does not turn ON
the smart FET. Because the DTC cannot be reproduced in this state, perform 

EXL-75, "Diagnosis

Procedure"

 and replace IPDM E/R after the malfunctioning part is repaired. Refer to 

PCS-67,

"Removal and Installation"

. 

2.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

1.

Turn ignition switch OFF.

2.

Turn ignition switch ON.

3.

Turn lighting switch 1ST, and front fog lamp switch ON.

4.

Select “Self Diagnostic Result” mode of “IPDM E/R” using CONSULT.

5.

Check DTC.

Is DTC detected?

YES

>> Refer to 

EXL-75, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-41, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010452521

1.

CHECK FRONT FOG LAMP LH POWER SUPPLY CIRCUIT (SHORT)

1.

Turn ignition switch OFF.

4.

With operating the test items, check the voltage between front fog lamp LH harness connector and
ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace IPDM E/R. Refer to 

PCS-67, "Removal and Installation"

.

3.

CHECK FRONT FOG LAMP LH BULB

Check the front fog lamp LH bulb. Refer to 

EXL-76, "Component Inspection"

.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace front fog lamp LH bulb. Refer to
