• 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.

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

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