DTC Description
INFOID:0000000010469947
DTC DETECTION LOGIC
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
and replace IPDM E/R after the malfunctioning part is repaired. Refer to
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
EXL-259, "Diagnosis Procedure"
.
NO-1
>> To check malfunction symptom before repair: Refer to
GI-41, "Intermittent Incident"
NO-2
>> Confirmation after repair: INSPECTION END
Diagnosis Procedure
INFOID:0000000010469948
1.
CHECK HEADLAMP (LO) LH POWER SUPPLY CIRCUIT (SHORT)
1.
Turn ignition switch OFF.
2.
Turn lighting switch OFF.
3.
Disconnect IPDM E/R connector and headlamp low LH connector.
DTC No.
