Nissan Sentra Service Manual: Front fog lamp circuit
Description
The ipdm e/r (intelligent power distribution module engine room) controls the front fog lamp relay based on inputs from the bcm over the can communication lines. When the front fog lamp relay is energized, power flows from the front fog lamp relay in the ipdm e/r to the front fog lamps.
Component Function Check
1.Check front fog 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 front fog lamp is turned ON.
With consult
- Select EXTERNAL LAMP of IPDM E/R active test item.
- While operating the test items, check that the front fog lamp is turned on.
Fog : front fog lamp on
Off : front fog lamp off
Is the inspection result normal? YES >> Front fog lamp circuit is normal.
NO >> Refer to EXL-94, "Diagnosis Procedure".
Diagnosis Procedure
Regarding Wiring Diagram information, refer to EXL-53, "Wiring Diagram".
1.Check front fog lamp fuse
- Turn the ignition switch off.
- Check that the following fuse is not blown.
Is the fuse blown? YES >> Replace the fuse after repairing the affected circuit.
NO >> GO TO 2.
2.Check front fog lamp output voltage
Consult
- Disconnect the front fog lamp harness connector in question.
- Turn the ignition switch on.
- Turn the front fog lamps on.
- Check the voltage between the front fog lamp harness connector and ground.
Is the inspection result normal? Yes >> go to 4.
NO >> GO TO 3.
3.Check front fog lamp open circuit
- Turn the ignition switch off.
- Disconnect IPDM E/R connector.
- Check continuity between the ipdm e/r harness connector and the front fog lamp harness connector.
Is the inspection result 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 front fog lamp ground circuit
- Turn the ignition switch off.
- Check continuity between the front fog lamp harness connector terminal 2 and ground.
Is the inspection result normal? YES >> Inspect the fog lamp bulb.
NO >> Repair or replace the harness or connector.
