PARKING LAMP CIRCUIT

Description

INFOID:0000000006179033

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

1.

CHECK PARKING LAMP OPERATION

WITHOUT CONSULT-III

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

PCS-11, "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. While operating the test item, check that the parking lamp is turned ON.

Is the parking lamp turned ON?

YES

>> Parking lamp circuit is normal.

NO

>> Refer to 

EXL-47, "Diagnosis Procedure - Without Daytime Light System"

, 

EXL-50, "Diagnosis

Procedure - With Daytime Light System"

.

Regarding Wiring Diagram information, refer to 

EXL-107, "Wiring Diagram"

.

1.

CHECK PARKING LAMP 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.

5. With the parking lamps ON, check voltage between the front

combination lamp connectors and ground.

6. With the parking lamps ON, check voltage between the rear

combination lamp connectors and ground.

7. With the parking lamps ON, check voltage between the license

plate lamp connector and ground

Are voltage readings as specified?

YES

>> GO TO 4.

NO

>> GO TO 3.

3.

CHECK PARKING, LICENSE PLATE AND TAIL LAMP CIRCUIT (OPEN)

1. Turn the ignition switch OFF.

2. Disconnect IPDM E/R connector E124.

3. Check continuity between the IPDM E/R harness connector (A)

and the front combination lamp harness connector (B).
