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. Vehicle's fuel tank is fully filled. When determining whether to perform initialization or reinitialization, refer to the following

InitializationWhen the headlight leveler control module has been replaced with a new part.
ReinitializationWhen the headlight leveler control module has been replaced with a part from a different vehicle. When suspension parts have been removed or replaced. (Crossmember, transverse link, lateral link, strut) When the vehicle height sensor has been replaced or removed.

INITIALIZATION OR REINITIALIZATION REFERENCE CHART

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. Refer to «ADJUSTMENT»(ref-325323-S02475391542009071800000) , Headlight Assembly .

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. Refer to «ADJUSTMENT»(ref-325323-S02475391542009071800000) , Headlight Assembly .
CAUTIONIf 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 . Refer to PROCEDURE , Auto Headlight Beam Leveler System .

HID HEADLIGHT BALLAST

CAUTIONDo not work with wet hands. Because the lighting circuit on the HID headlights uses high voltage, be sure to confirm that the power supply is turned off before operation. Do not leave the headlight without a ballast for extended periods of time. Dust, moisture, etc. entering the headlight may affect its performance.
  1. Disconnect the ground cable from the battery.
  2. Remove the headlight assembly. Refer to «REMOVAL»(ref-325323-S03837004962009071800000) , Headlight Assembly .
  3. Remove the back cover.
  4. Disconnect the harness connector.
  5. Disconnect the harness connector, loosen the screws, and remove the headlight ballast.
  6. Disconnect the connector from the headlight ballast.

Tightening torque

1.3 N.m (0.13 kgf-m, 0.96 ft-lb)

CAUTIONWhen installing the ballast cover, be sure to install the gasket. After installing the ballast to the vehicle, be sure to perform beam adjustment

Note. Adjust the projector lens to near the center of the extension opening before installing the ballast. This makes the beam adjustment work easier.

HIGH BEAM & HALOGEN TYPE LOW BEAM

CAUTIONBecause the halogen bulb operates at a high temperature, dirt and oil on the bulb surface reduces the bulb's service life. Hold the flange portion when replacing the bulb. Never touch the glass portion. Do not leave the headlight without a bulb for a long time. Dust, moisture, etc. entering the headlight may affect its performance.
  1. Disconnect the ground cable from the battery.
  2. Remove the air intake duct (rear). (When removing the headlight bulb RH).
  3. Disconnect the harness connector.
  4. Remove the bulb assembly (A) then remove the high beam. To remove the low beam, remove the back cover (B), and then go to Step 5.
  5. Disconnect the connector, and remove the bulb.

When replacing the bulb, hold the flange portion, and never touch the glass. Do not leave the headlight without a bulb for a long time. Dust, moisture, etc. entering the headlight may affect its performance.

HALOGEN TYPE

  1. Visually check the bulb for blow out.
  2. Check the bulb specification.
  3. If NG, replace the bulb with a new part.

HID TYPE

CAUTIONDo not work with wet hands. Do not touch the harness, inner headlight, or any metallic portion of the headlight when the light is illuminated (when the lighting switch is turned on). When performing a lighting test, make sure that the headlight is mounted on the vehicle, and that the power supply is connected to the connector on the vehicle side.
  1. Check the bulb specification.
  2. Install a SUBARU genuine HID bulb to test whether it lights properly.
  3. If the headlight does not illuminate, replace the bulb with a new part.
  4. Check the HID ballast. Check the ballast in the following methods, and judge whether or not it can be reused. Perform the cold start (turning on the lights after the headlights have been off for 10 minutes or more) and hot start (turning on the headlights for 15 minutes or more --> turning off the lights for one minute --> turning on the lights again) several times and check if the headlights illuminate properly. Check the lighting condition immediately after the cold start until stable (approx. 5 min.), to make sure that an unstable condition (flicker etc.) does not occur. Attach two bulbs with equal amounts of operating hours to the right and left headlights, and light the headlights for approx. 30 minutes. Check to make sure that there is no difference in brightness between the right and left headlights.
  5. If NG, replace the ballast with a new part.

FOG LIGHT AIMING

Note. Before checking the fog light beam level, make sure the following

  1. The area around the fog light has not sustained any accident, damage or other type of deformation.
  2. Make sure that the vehicle is parked on a level surface.
  3. Make sure that the inflation pressure of tires are correct.
  4. Make sure that the vehicle fuel tank is full.
  1. Bounce the vehicle two to three times to normalize the suspension.
  2. Make certain that someone is seated in the driver's seat.
  3. Disengage the three clips, and then turn over the mud guard.
  4. Adjust the front fog light pattern by inserting a Phillips screwdriver to the adjusting hole.
