FRONT FOG LAMP CIRCUIT

Description

INFOID:0000000006179030

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

inputs from the BCM via 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:0000000006179031

1.

CHECK FRONT FOG LAMP OPERATION

WITHOUT CONSULT-III

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-III

1. Select "EXTERNAL LAMPS" 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-45, "Diagnosis Procedure"

Diagnosis Procedure

INFOID:0000000006179032
