DTC Description

INFOID:0000000010452605

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector
• Front combination lamp LH internal circuit
- LED (Daytime running light)
- Control circuit
- Harness
• IPDM E/R

FAIL-SAFE

Shuts off the power supply to the daytime running light LH power supply circuit until the daytime running light
ON conditions are no longer satisfied.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

With CONSULT

1.

Turn ignition switch ON.

2.

Select “DTRL 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 daytime running light 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-91,

"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.

Start engine.

3.

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

4.

Check DTC.

Is DTC detected?

YES

>> Refer to 

EXL-91, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to
