Diagnosis Procedure

HEADLAMP (HI) CIRCUIT


Description

The high beam solenoid drives the mobile valve shade. And the mobile valve shade switches the high beam and low beam of headlamp.
- When the headlamp high relay is turned ON, magnetic force is applied to the high beam solenoid (1) by a current. The mobile valve shade (2) is switched to the high beam position.
- When the headlamp high relay is turned OFF, the current stops.
The mobile valve shade returns to the low beam position automatically.








HEADLAMP (HI) CIRCUIT


Diagnosis Procedure

1.CHECK HEADLAMP (HI) OUTPUT VOLTAGE
CONSULT-III ACTIVE TEST
1. Turn the ignition switch OFF.
2. Disconnect the front combination lamp 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 (HI) 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 front combination lamp harness connector.





Does continuity exist?
YES - GO TO 5.
NO - Repair the harnesses or connectors.
3.CHECK HEADLAMP (HI) 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 FRONT COMBINATION LAMP (HI) SHORT CIRCUIT
1. Disconnect IPDM E/R connector.
2. Check continuity between the IPDM E/R harness connector terminal 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 (HI) GROUND OPEN CIRCUIT
Check continuity between the front combination lamp harness connector and the ground.





Does continuity exist?
YES - Replace the front combination lamp.
NO - Repair the harnesses or connectors.
