Nissan Maxima Service and Repair 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 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
- Activate IPDM E/R auto active test. Refer to PCS-11, "Diagnosis
Description".
- Check that the parking lamp is turned ON.
CONSULT
- Select "EXTERNAL LAMPS" of IPDM E/R active test item.
- While operating the test item, check that the parking lamp is
turned ON.
TAIL : Parking lamp ON
OFF : Parking lamp OFF
Diagnosis Procedure
1.CHECK PARKING LAMP FUSES
- Turn the ignition switch OFF.
- Check that the following fuses are not open.

2.CHECK TAIL LAMP RELAY OUTPUT (VOLTAGE)
CONSULT



- Turn the ignition switch OFF.
- Disconnect the front and rear combination lamp connectors.
- Turn the ignition switch ON.
- Select "EXTERNAL LAMPS" of IPDM E/R active test item.
- With EXTERNAL LAMPS ON, check the voltage between the front
combination lamp connector and ground.
- With EXTERNAL LAMPS ON, check the voltage between the rear
combination lamp connector and ground.
- With EXTERNAL LAMPS ON, check the voltage between the license plate
lamp connector and ground.



3.CHECK PARKING LAMP CIRCUIT (OPEN)



- Turn the ignition switch OFF.
- Disconnect IPDM E/R connector E201.
- Check continuity between the IPDM E/R harness connector (A) and
the front combination lamp harness connector (B).
- Check continuity between the IPDM E/R harness connector (A) and the
rear combination lamp harness connector (B).
- Check continuity between the IPDM E/R harness connector (A) and the
license plate lamp harness connector (B)



4.CHECK PARKING LAMP GROUND CIRCUIT



- Check continuity between the front combination lamp harness
connector terminal and ground.
- Check continuity between the rear combination lamp harness connector
terminal and ground.
- Check continuity between the license plate lamp harness connector
terminal and ground.
