Parking Lamp Circuit

PARKING LAMP CIRCUIT

Description

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 51 and 52, located in the IPDM E/R. Power then flows to the front and rear combination lamps, license plate lamps.


Component Function Check


1. CHECK PARKING LAMP OPERATION

WITHOUT CONSULT
1.Activate IPDM E/R auto active test. Refer to "Diagnosis Description" Diagnosis Description.
2.Check that the parking lamp is turned ON.
WITH CONSULT
1.Select EXTERNAL LAMPS of IPDM E/R active test item.
2.While operating the test items, check that the parking lamp is turned ON.
TAIL: Parking lamp ON


Off: Parking lamp OFF
Is the parking lamp turned ON?
YES- Parking lamp circuit is normal.
NO- Refer to "Diagnosis Procedure" Turn Signal Lamp Circuit.


Diagnosis Procedure

Regarding Wiring Diagram information, refer to "Wiring Diagram" Electrical Diagrams.

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 combination lamp connectors, front side marker lamp connectors, rear combination lamp connectors and license plate lamp connectors.
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 connector and ground.

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





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





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

6.Check continuity between the IPDM E/R harness connector and license plate lamp connector.





Are the inspection results normal?
YES- Replace IPDM E/R. Refer to "Removal and Installation" Service and Repair.
NO- Repair or replace the harness or connector.

4. CHECK PARKING LAMP GROUND CIRCUITS

1.Check continuity between the front combination lamp harness connector and ground.





2.Check continuity between the front side marker lamp harness connector and ground.





3.Check continuity between the rear combination lamp harness connector and ground.





4.Check continuity between the license plate lamp harness connector and ground.





Are the inspection results normal?
YES- Inspect the parking lamp bulb.
