HEADLAMP (LO) CIRCUIT

WITHOUT DAYTIME RUNNING LIGHT SYSTEM : Diagnosis Procedure


1. CHECK HEADLAMP (LO) OUTPUT VOLTAGE

CONSULT ACTIVE TEST
1.Turn the ignition switch OFF.
2.Disconnect the headlamp connector.
3.Turn the ignition switch ON.
4.Select "EXTERNAL LAMPS" of IPDM E/R active test item.
5.With operating the test items, check the voltage between the IPDM E/R harness connector and the ground.





Is the measurement value normal?
YES- GO TO 2.
NO- GO TO 3.

2. CHECK HEADLAMP (LO) OPEN CIRCUIT

1.Turn the ignition switch OFF.
2.Disconnect IPDM E/R connector.
3.Check continuity between the IPDM E/R harness connector and the headlamp harness connector.





Does continuity exist?
YES- GO TO 5.
NO- Repair the harnesses or connectors.

3. CHECK HEADLAMP (LO) FUSE

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





Is the fuse fusing?
YES- GO TO 4.
NO- Replace IPDM E/R.

4. CHECK HEADLAMP (LO) SHORT CIRCUIT

1.Disconnect the IPDM E/R connector.
2.Check continuity between the IPDM E/R harness connector and the ground.





Does continuity exist?
YES- Repair the harnesses or connectors. And then replace the fuse.
NO- Replace the fuse. (Replace IPDM E/R if the fuse is fusing again.)

5. CHECK HEADLAMP (LO) GROUND OPEN CIRCUIT

Check continuity between the headlamp harness connector and the ground.





Does continuity exist?
YES- Replace the headlamp (LO) bulb. (Bulb socket is abnormally.)
NO- Repair the harnesses or connectors.
