Auto Headlight Beam Leveler System

PROCEDURE

When parts related to the auto headlight beam leveling 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.
- When determining whether to perform initialization or reinitialization, refer to the following:






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. Adjustments

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 ON, and within a period over 1.5 seconds and under 10 seconds, repeat headlight switch OFF => ON 5 times or more.
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 a period over 1.5 seconds and under 10 seconds, repeat headlight switch OFF => ON 5 times or more.
7. Confirm that the indicator in the meter flashes 3 times and turns OFF, completing the reinitialization. (At this time, the headlight beam adjustment is lowered, and then returns to the original position.)
8. Perform beam adjustment for the headlight. Adjustments

CAUTION: If the indicator does not flash 3 times or the headlight beam does not operate, there is a possibility of an open circuit or faulty connection in the harness between the headlight leveler control module, front and rear vehicle height sensors and headlight assembly. Perform inspection and repair according to the inspection results, then perform initialization/reinitialization again. Refer to INSPECTION, Auto Headlight Beam Leveler System.
