HEADLAMP (LO) CIRCUIT

5. With EXTERNAL LAMPS ON, check the voltage between the

combination lamp connector and ground.

Is battery voltage present?

YES

>> GO TO 4.

NO

>> GO TO 3.

3.

CHECK HEADLAMP (LO) CIRCUIT FOR OPEN

YES

>> Replace the IPDM E/R. Refer to 

PCS-35, "Removal and

Installation"

.

NO

>> Repair the harnesses or connectors.

4.

CHECK FRONT COMBINATION LAMP (LO) GROUND CIRCUIT

1. Disconnect the front combination lamp connector.

2. Check continuity between the front combination lamp harness

connector terminal and ground.

Does continuity exist?

YES

>> Inspect the headlamp bulb.

NO

>> Repair the harness.

FRONT FOG LAMP CIRCUIT

Description

INFOID:0000000010051064

The IPDM E/R (intelligent power distribution module engine room) controls the front fog lamp relay based on

inputs from the BCM over the CAN communication lines. When the front fog lamp relay is energized, power

flows from the front fog lamp relay in the IPDM E/R to the front fog lamps. 

Component Function Check

INFOID:0000000010051065

1.

CHECK FRONT FOG LAMP OPERATION

WITHOUT CONSULT

1. Activate IPDM E/R auto active test. Refer to 

PCS-11, "Diagnosis Description"

.

2. Check that the front fog lamp is turned ON.

CONSULT

1. Select "EXTERNAL LAMPS" of IPDM E/R active test item.

2. While operating the test item, check that the front fog lamp is turned ON.

Is the front fog lamp turned ON?

YES

>> Front fog lamp circuit is normal.

NO

>> Refer to 

EXL-207, "Diagnosis Procedure"

. 

Diagnosis Procedure

INFOID:0000000010051066

Regarding Wiring Diagram information, refer to 

EXL-276, "Wiring Diagram"

.

1.

CHECK FRONT FOG LAMP FUSE

1. Turn the ignition switch OFF.

2. Check that the following fuse is not open.

Is the fuse open?

YES

>> Repair the harness and replace the fuse.

NO

>> GO TO 2.

2.

CHECK FRONT FOG LAMP OUTPUT VOLTAGE

CONSULT

1. Turn the ignition switch OFF.

2. Disconnect the front fog lamp connector.

3. Turn the ignition switch ON.

4. Select "EXTERNAL LAMPS" of IPDM E/R active test item.

PARKING LAMP CIRCUIT

Description

INFOID:0000000010051067

The IPDM E/R (intelligent power distribution module engine room) controls the tail lamp relay based on inputs

from the BCM over the CAN communication lines. When the tail lamp relay is energized, power flows through

fuses 46 and 47, located in the IPDM E/R. Power then flows to the front and rear combination lamps, license

plate lamps.

Component Function Check

INFOID:0000000010051068

1.

CHECK PARKING LAMP OPERATION

WITHOUT CONSULT

1. Activate IPDM E/R auto active test. Refer to
