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 37, located in the IPDM E/R. Power then flows through the tail lamp relay 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. Diagnosis Description.
2.Check that the parking lamps are turned ON.
CONSULT
1.Select "EXTERNAL LAMPS" of IPDM E/R active test item.
2.While operating the test items, check that the parking lamps are turned ON.

TAIL: Parking lamp ON
OFF: Parking lamp OFF

Is the parking lamp turned ON?
YES- Parking lamp circuit is normal.
NO- .


Diagnosis Procedure

Regarding Wiring Diagram information, Parking, License Plate And Tail Lamps System.

1. CHECK PARKING LAMP FUSES

1.Turn the ignition switch OFF.
2.Check that the following fuse is not open.





Is the fuse open?
YES- Replace the fuse after repairing the affected circuit.
NO- GO TO 2.

2. CHECK PARKING LAMP BULB

Check the applicable lamp bulb to be sure the proper bulb standard is in use and the bulb is not open.
Is the bulb OK?
YES- GO TO 3.
NO- Replace the bulb.

3. CHECK TAIL LAMP RELAY OUTPUT (VOLTAGE)

1.Turn the ignition switch OFF.
2.Disconnect the front combination lamp connector, rear combination lamp connector and license plate lamp connector.
3.Turn the ignition switch ON.
4.Turn the parking lamps ON.
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 5.
NO- GO TO 4.

4. CHECK PARKING, LICENSE PLATE AND TAIL 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 rear combination lamp harness connector.





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





Are continuity test results as specified?
YES- Replace IPDM E/R. Service and Repair.
NO- Repair the harness or connector.

5. CHECK PARKING, LICENSE AND TAIL LAMP GROUND CIRCUITS

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





2.Check continuity between the rear combination lamp harness connectors and ground.





3.Check continuity between the license plate lamp harness connectors and ground.





Does continuity exist?
YES- Replace the malfunctioning lamp.
NO- Repair the harness.
