DTC Description

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector

• Parking lamp LH bulb

• Parking lamp RH bulb

• Parking lamp LH bulb socket or harness

• Parking lamp RH bulb socket or harness

• Front combination lamp LH

  • LED (front side marker lamp)

• Front combination lamp RH

  • LED (front side marker lamp)

• IPDM E/R

FAIL-SAFE

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

Dtc Confirmation Procedure

DTC Confirmation Procedure

1. PRECONDITIONING

   1. CONSULT

      1. Ignition switch ON.

      2. Select "Park lamp (LH) circ malfunctn" and "Park lamp (RH) circ malfunctn" in “Data Monitor” mode of “IPDM E/R”.

      3. Check the monitor status.

         Monitor item	Monitor status
         Park lamp (LH) circ malfunctn	0
         	1
         Park lamp (RH) circ malfunctn	0
         	1

   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, refer to DTC Diagnosis Procedure and replace IPDM E/R after the malfunctioning part is repaired. Refer to Removal and Installation.

2. PERFORM DTC CONFIRMATION PROCEDURE

   1. CONSULT

      1. Ignition switch OFF.

      2. Ignition switch ON.

      3. Turn lighting switch 1ST.

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

      5. Check DTC.

   Is DTC detected?

   YES >>

   Refer to DTC Diagnosis Procedure.

   NO >>

   To check malfunction symptom before repair: Refer to Intermittent Incident.

   NO >>

   Confirmation after repair: Inspection End.

Dtc Diagnosis Procedure

DTC Diagnosis Procedure

1. CHECK PARKING LAMP POWER SUPPLY CIRCUIT (SHORT)

   1. 1. Ignition switch OFF.

      2. Turn lighting switch OFF.

      3. Disconnect IPDM E/R connector, front combination lamp LH connector and front combination lamp RH connector.

      4. Check continuity between IPDM E/R harness connectors and ground.

         IPDM E/R			—	Continuity
         Connector		Terminal
         RH	E44	61	Ground	No
         LH	E48	56

   Is the inspection result normal?

   YES >>

   GO TO 2.

   NO >>

   Repair or replace harness.

2. CHECK PARKING LAMP POWER SUPPLY

   1. CONSULT

      1. Connect IPDM E/R connector.

      2. Ignition switch ON.

      3. Select “PARKING LAMP” in “Active Test” mode of “IPDM E/R”.

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

         +			-	Test item		Voltage (Approx.)
         Front combination lamp
         Connector		Terminal
         RH	E20	1	Ground	PARKING LAMP	On	Battery voltage
         					Off	0V
         LH	E21				On	Battery voltage
         					Off	0V

   Is the inspection result normal?

   YES >>

   GO TO 3.

   NO >>

   Replace IPDM E/R. Refer to Removal and Installation.

3. CHECK PARKING LAMP

   1. Check the parking lamp. Refer to Component Inspection.

   Is the inspection result normal?

   YES >>

   GO TO 4.

   NO >>

   Repair or replace the malfunctioning part.

4. CHECK FRONT SIDE MARKER LAMP

   1. Check the front side marker lamp. Refer to Component Inspection.

   Is the inspection result normal?

   YES >>

   Inspection End.

   NO >>

   Repair or replace the malfunctioning part.
