POSSIBLE CAUSE

• Harness or connector
• Headlamp (LO) LH bulb
• IPDM E/R

FAIL-SAFE

Shuts off the power supply to the headlamp (LO) LH power supply circuit until the headlamp (LO) ON condi-
tions are no longer satisfied.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

With CONSULT

1.

Turn ignition switch ON.

2.

Select “HL (LO) 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 headlamp (LO) LH power supply circuit, and dam-

age 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-259, "Diag-

nosis 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 2ND.

4.

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

5.

Check DTC.

Is DTC detected?

YES

>> Refer to
