B20CB DAYTIME RUNNING LIGHT LH POWER SUPPLY CIRCUIT
DTC Description
INFOID:0000000010788806
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
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.
Start engine.
3.
Select “Self Diagnostic Result” mode of “IPDM E/R” using CONSULT.
4.
Check DTC.
Is DTC detected?
YES
>> Refer to
EXL-121, "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:0000000010788807
1.
CHECK DAYTIME RUNNING LIGHT LH POWER SUPPLY CIRCUIT (SHORT)
DTC No.

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 DAYTIME RUNNING LIGHT LH
Check the daytime running light LH. Refer to
EXL-122, "Component Inspection"
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Replace front combination lamp LH. Refer to
EXL-191, "Removal and Installation"
.
Component Inspection
INFOID:0000000010788808
1.
CHECK DAYTIME RUNNING LIGHT LH
1.
Turn ignition switch OFF.
2.
