FRONT FOG LAMP CIRCUIT
Description
INFOID:0000000005274741
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:0000000005274742
1.
CHECK FRONT FOG LAMP OPERATION
WITHOUT CONSULT-III
1.
Activate IPDM E/R auto active test. Refer to
PCS-13, "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
.

PARKING LAMP CIRCUIT
Description
INFOID:0000000005274744
The IPDM E/R (intelligent power distribution module engine room) controls the tail lamp relay based on inputs
from the BCM via the CAN communication lines. When the tail lamp relay is energized, power flows through
fuse 37, located in the IPDM E/R. Power then flows to the front and rear combination lamps.
Component Function Check
INFOID:0000000005274745
1.
CHECK PARKING LAMP OPERATION
WITHOUT CONSULT-III
1.
Activate IPDM E/R auto active test. Refer to
PCS-13, "Diagnosis Description"
.
2.
Check that the parking 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 parking lamp is turned ON.
Is the parking lamp turned ON?
YES
>> Parking lamp circuit is normal.
NO
>> Refer to
.
Diagnosis Procedure
INFOID:0000000005274746
Regarding Wiring Diagram information, refer to
.
1.
CHECK PARKING LAMP FUSES
1.
Turn the ignition switch OFF.
2.
Check that the following fuses are not open.
Is the fuse open?
