B20D2 PARKING LAMP POWER SUPPLY CIRCUIT

DTC Description

INFOID:0000000010469953

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector
• Front combination lamp LH internal circuit
- LED (Parking lamp)
- Control circuit
- Harness
• Front combination lamp RH internal circuit
- LED (parking lamp)
- Control circuit
- Harness
• IPDM E/R

FAIL-SAFE

Shuts off the power supply to the parking lamp (LH/RH) power supply circuit until the parking lamp, license
plate lamp, and tail lamp ON conditions are no longer satisfied.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

With CONSULT

1.

Turn ignition switch ON.

2.

Select “P LAMP 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 parking lamp LH or parking lamp RH 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-264, "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.

4.

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

5.

Check DTC.

Is DTC detected?

YES

>> Refer to 

EXL-264, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-41, "Intermittent Incident"

.

DTC No.
