B20D2 PARKING LAMP POWER SUPPLY CIRCUIT
DTC Description
INFOID:0000000010452550
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-102, "Diagnosis Procedure"
and replace IPDM E/R after the malfunctioning part is repaired.
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-102, "Diagnosis Procedure"
.
NO-1
>> To check malfunction symptom before repair: Refer to
GI-41, "Intermittent Incident"
DTC No.

4.
With operating the test items, check the voltage between front combination lamp harness connector and
ground.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Replace IPDM E/R. Refer to
PCS-67, "Removal and Installation"
3.
CHECK PARKING LAMP
Check the parking lamp. Refer to
EXL-102, "Component Inspection"
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Replace the corresponding front combination lamp. Refer to
