Component Tests and General Diagnostics

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 over the CAN communication lines. When the tail lamp relay is energized, power flows through fuses 46 and 47, 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. Diagnosis Description.
2.Check that the parking lamp is turned ON.
CONSULT
1.Select "EXTERNAL LAMP" of IPDM E/R active test item.
2.With 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".


Diagnosis Procedure

Regarding Wiring Diagram information, Parking, License Plate And Tail Lamps Coupe (coupe) or Parking, License Plate And Tail Lamps Sedan (sedan).

1. CHECK FUSES

1.Turn the ignition switch OFF.
2.Check that the following fuses are not open.





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

2. CHECK TAIL LAMP RELAY OUTPUT (VOLTAGE)

CONSULT
1.Turn the ignition switch OFF.
2.Disconnect the front and rear combination lamp connectors, license plate lamp connectors.
3.Turn the ignition switch ON.
4.Select "EXTERNAL LAMP" of IPDM E/R active test item.
5.With EXTERNAL LAMP ON, check the voltage between the front combination lamp connector, rear combination lamp connector, license plate lamp connector and ground.









Is battery voltage present?
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, rear combination lamp harness connector, license plate lamp harness connector.





Does continuity exist?
YES- Replace IPDM E/R. Service and Repair.

NO- Repair the harnesses or connectors.

4. CHECK PARKING LAMP GROUND CIRCUIT

1.Disconnect the combination lamp connector.
2.Check continuity between the front combination lamp harness connector, rear combination lamp harness connector, license plate lamp harness connector and ground.





Does continuity exist?
YES- Inspect the parking lamp bulb.
NO- Repair the harness.
