Nissan Sentra Service Manual: 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 fuse 36, 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
- 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).
- Check that the parking lamp is turned on.
Without consult
- Select external lamp of ipdm e/r active test item
- While operating the test items, check that the parking lamp is turned on.
Tail : parking lamp on
Off : parking lamp off
Is the inspection result normal? Yes >> parking lamp circuit is normal.
No >> refer to exl-96, "diagnosis procedure".
Diagnosis procedure
Regarding wiring diagram information, refer to exl-68, "wiring diagram".
1.Check parking lamp fuses
- Turn the ignition switch off.
- 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)
- Disconnect the front or rear combination lamp connector or license plate lamp connector in question.
- Turn the ignition switch on.
- Turn the parking lamps on.
- With the parking lamps on, check voltage between the front combination lamp front (parking) connector and ground.
- With the parking lamps ON, check voltage between the front combination lamp (side marker) connector and ground.
- With the parking lamps on, check voltage between the rear combination lamp connector and ground.
- 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)
- Turn the ignition switch off.
- Disconnect ipdm e/r connector.
- Check continuity between the ipdm e/r harness connector and the front combination lamp (parking) harness connector.
- Check continuity between the ipdm e/r harness connector and the front combination lamp (side marker) harness connector.
- Check continuity between the ipdm e/r harness connector and the rear combination lamp harness connector.
- 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 pcs-30, "removal and installation" (with intelligent key system) or pcs-58, "removal and installation" (without intelligent key system).
No >> repair or replace the harness or connector.
4.Check parking lamp ground circuits
- Check continuity between the front combination lamp (parking) harness connector and ground.
- Check continuity between the front combination lamp (side marker) harness connector and ground.
- Check continuity between the rear combination lamp harness connector and ground.
- Check continuity between the license plate lamp harness connector and ground.
Are the inspection results normal? Yes >> inspect the parking lamp bulb.
No >> repair or replace the harness or connector.
