AUTO HEADLIGHT BEAM LEVELER SYSTEM

PROCEDURE
When parts related to the auto headlight beam leveler system are removed or replaced, perform the following procedures to initialize or reinitialize.

NOTE: Before performing initialization or reinitialization, check the following:
- Vehicle is parked on a level surface.
- The inflation pressure of tires is correct.
- Unload any cargo from the vehicle.
- Vehicle's fuel tank is fully filled.
- Refer to the following chart to determine whether to initialize or reinitialize.






1. INITIALIZATION
1. Confirm that the indicator in the meter is repeatedly flashing twice.
2. Bounce the vehicle several times to normalize the suspension.
3. Make certain that someone is seated in the driver's seat.
4. Turn the ignition ON, and within a period over 1.5 seconds and under 20 seconds, repeat headlight switch OFF => ON 3 times or more.
5. Confirm that the indicator in the meter flashes 3 times and turns OFF, completing the initialization. (At this time, the headlight beam adjustment is lowered, and then returns to the original position.)
6. Perform beam adjustment for the headlight.

2. REINITIALIZATION

1. Bounce the vehicle several times to normalize the suspension.
2. Make certain that someone is seated in the driver's seat.
3. Turn the ignition switch to ON, and, within 1.5 - 10 seconds, turn the headlight switch OFF => ON five or more successive times.
4. Check that the headlight beam drops once, then returns to normal.
5. After confirming 4), turn the ignition switch to OFF within 30 seconds.
6. Turn the ignition switch to ON again, and, within 1.5 - 10 seconds, turn the headlight switch OFF => ON five or more successive times.
7. Make sure that the indicator in the meter flashes three times and then turns OFF, indicating that reinitialization has been successfully completed. (At this time, the headlight beam drops once, and then returns to the original position.)
8. Perform beam adjustment for the headlight.

CAUTION:
If the indicator does not flash three times or the headlight beam does not operate, it can be assumed that there is an open circuit or faulty wiring in the harness of the auto headlight beam leveler control module, rear vehicle height sensors or headlight assembly. Perform inspection and repair according to the inspection results, then perform initialization/reinitialization again.
- Inspection: Refer to INSPECTION, Auto Headlight Beam Leveler System.
- Initialization: Refer to INITIALIZATION, PROCEDURE, Auto Headlight Beam Leveler System.
- Reinitialization: Refer to REINITIALIZATION, PROCEDURE, Auto Headlight Beam Leveler System.
