B20CF HEADLAMP (HI) RH POWER SUPPLY CIRCUIT

DTC Description

INFOID:0000000010788812

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector
• Front combination lamp RH internal circuit
- LED [Headlamp (HI)]
- LED headlamp control module
- Harness
• IPDM E/R

FAIL-SAFE

Shuts off the power supply to the headlamp (HI) RH power supply circuit until the headlamp (HI) ON conditions
are no longer satisfied.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

With CONSULT

1.

Turn ignition switch ON.

2.

Select “HL (HI) RH 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 (HI) RH 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-125, "Diag-

nosis Procedure"

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

PCS-

60, "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, and lighting switch HI.

4.

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

5.

Check DTC.

Is DTC detected?

YES

>> Refer to 

EXL-125, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010788813

1.

CHECK HEADLAMP (HI) RH POWER SUPPLY CIRCUIT (SHORT)

DTC No.

4.

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

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace IPDM E/R. Refer to 

PCS-60, "Removal and Installation"

.

3.

CHECK HEADLAMP (HI) RH

Check the headlamp (HI) RH. Refer to 

EXL-126, "Component Inspection"

.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace front combination lamp RH. Refer to 

EXL-191, "Removal and Installation"

.

Component Inspection

INFOID:0000000010788814

1.

CHECK HEADLAMP (HI) RH

1.

Turn ignition switch OFF.

2.

Disconnect front combination lamp RH connector.

3.

Check resistance of front combination lamp RH terminals.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace front combination lamp RH. Refer to 

EXL-191, "Removal and Installation"
