PARKING LAMP CIRCUIT

PARKING LAMP CIRCUIT

Description

INFOID:0000000009757519

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

fuse 36, located in the IPDM E/R. Power then flows to the front and rear combination lamps, license plate

lamps.

1.

CHECK PARKING LAMP OPERATION

WITHOUT CONSULT

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

EXL-24, "Diagnosis Description"

 (with Intelligent Key system)

or 

EXL-28, "Diagnosis Description"

 (without Intelligent Key system).

2. Check that the parking lamp is turned ON.

WITH CONSULT 

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

2. While operating the test items, check that the parking lamp is turned ON.

Is the inspection result normal?

YES

>> Parking lamp circuit is normal.

NO

>> Refer to 

EXL-96, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009757521

Regarding Wiring Diagram information, refer to 

EXL-68, "Wiring Diagram"

.

1.

CHECK PARKING LAMP FUSES

1. Turn the ignition switch OFF.

2. Check that the following fuses are not blown.

Is the fuse blown?

YES

>> Replace the blown fuse after repairing the affected circuit.

NO

>> GO TO 2.

2.

CHECK TAIL LAMP RELAY OUTPUT (VOLTAGE)

1. Disconnect the front or rear combination lamp connector or license plate lamp connector in question.

2. Turn the ignition switch ON.

3. Turn the parking lamps ON.

4. With the parking lamps ON, check voltage between the front combination lamp front (parking) connector

and ground.

5. With the parking lamps ON, check voltage between the front combination lamp (side marker) connector

and ground.

6. With the parking lamps ON, check voltage between the rear combination lamp connector and ground.

7. With the parking lamps ON, check voltage between the license plate lamp connector and ground.

Are the inspection results normal?

YES

>> GO TO 4.

NO

>> GO TO 3.

3.

CHECK PARKING LAMP CIRCUIT (OPEN)

1. Turn the ignition switch OFF.

2. Disconnect IPDM E/R connector.

3. Check continuity between the IPDM E/R harness connector and the front combination lamp (parking) har-

ness connector.

4. Check continuity between the IPDM E/R harness connector and the front combination lamp (side marker)

harness connector.

5. Check continuity between the IPDM E/R harness connector and the rear combination lamp harness con-

nector.
