HEADLAMP (LO) CIRCUIT

Description

INFOID:0000000004216391

The IPDM E/R (intelligent power distribution module engine room) controls the headlamp low relay based on

inputs from the BCM over the CAN communication lines. When the headlamp low relay is energized, power

flows through fuses 51 and 52, located in the IPDM E/R. Power then flows to the front combination lamps to

the headlamp low beam.

Component Function Check

INFOID:0000000004216392

1.

CHECK HEADLAMP (LO) OPERATION

WITHOUT CONSULT-III

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

PCS-14, "Diagnosis Description"

.

2. Check that the headlamp is turned ON.

NOTE:

HI/LO is repeated 1 second each when using the IPDM E/R auto active test.

CONSULT-III

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

2. With operating the test items, check that the headlamp is turned ON.

Is the headlamp turned ON?

YES

>> Headlamp (LO) is normal.

NO

>> Refer to 

EXL-41, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000004216393

1.

CHECK HEADLAMP (LO) FUSES

1. Turn the ignition switch OFF.

2. Check that the following fuses are not open.

Is the fuse open?

YES

>> Repair the harness and replace the fuse.

NO

>> GO TO 2

2.

CHECK HEADLAMP (LO) OUTPUT VOLTAGE

CONSULT-III

1. Turn the ignition switch OFF.

2. Disconnect the front combination lamp connector.

3. Turn the ignition switch ON.

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

FRONT FOG LAMP CIRCUIT

Description

INFOID:0000000004216394

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:0000000004216395

1.

CHECK FRONT FOG LAMP OPERATION

WITHOUT CONSULT-III

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

PCS-14, "Diagnosis Description"

.

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

CONSULT-III

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

2. With operating the test items, 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-43, "Diagnosis Procedure"

.
