CAUTION

  1. Before removing or installing parts, always disconnect the battery ground cable from battery. When replacing the radio, control unit, and other parts provided with memory functions, record the memory contents before disconnecting the battery ground cable. Otherwise, the memory is cleared.
  2. Reassemble the parts in the reverse order of disassembly procedure unless otherwise indicated.
  3. Adjust parts to the given specifications.
  4. Connect the connectors and hoses securely during reassembly.
  5. After reassembly, make sure functional parts operate smoothly.
WARNINGThe air bag system wiring harness is routed near electrical parts and switches. All airbag system wiring harnesses and connectors are colored yellow. Do not use the electrical test equipment on these circuits. Be careful not to damage the air bag system wiring harness when servicing electrical parts and switches.

HID HEADLIGHT BALLAST

CAUTIONDo not operate with wet hands. As the lightening circuit on the HID headlights uses high voltage, be sure to confirm that the power supply is turned off before working on it. Do not leave the headlight without a ballast for a long time. Dust, moisture, etc. entering the headlight may affect its performance.

  6. Disconnect the connector from the headlight ballast. CAUTION: Be careful because the notch is easily bent.
  7. Turn the beam adjustment screw so that the beam is facing upward, then create space for the socket portion to pass through the inside of the lamp. CAUTION: The reflector should not interfere with the extension case.
  8. Place the socket portion toward the front side of the reflector bracket.
  9. Turn the beam adjustment screw so that the beam is facing downward, then create space for the socket portion to pass under the reflector bracket. CAUTION: The reflector should not interfere with the extension case.
  10. Remove the socket from headlight from below the housing. CAUTION: The socket should not get sandwiched between the reflector and the lamp housing.

  1. Cut the tip of packing (A) at an angle of 45°.
  2. With the cut end facing upward, insert packing (A) into the seal groove. CAUTION: If the packing protrudes, slowly take it off the groove. Do not stretch the packing. If the packing is stretched, seal fails.
  3. After making a round of the seal, cut its tip at an angle of 45°, with its length 10 mm (0.39 in) longer than the circumference of seal so that the tip overlaps the other. Then, press it onto the seal, using a screwdriver.
  4. Match the positions of the lens and headlight assembly, and then insert the lens into the headlight assembly.
  5. Engage the hooks.
  6. Put the seal portion of headlight assembly into the water and check that water does not enter inside the headlight.
CAUTIONBe sure that water does not enter inside the headlight through the bulb socket and ventilation hole.

HEADLIGHT AIMING

CAUTIONTurn off the light before adjusting the headlight aiming. If it is necessary to inspect the aiming, do not turn on the lamp for more than two minutes.

Before checking the headlight beam level, be sure of the following

Note. The area around the headlight does not have any scratch, damage or other type of deformation. Vehicle is parked on a level surface. The inflation pressure of tires is correct. Vehicle's fuel tank is full. Bounce the vehicle several times to normalize the suspension. Make certain that someone is seated in the driver's seat.

  1. Cover the headlight that is not being adjusted with a cloth.
  2. Turn the headlights on and then adjust the low beam while displaying the beam on the screen.

Note. Adjust the vertical beam level (A) first, then horizontal beam level (B) using a screwdriver.

HALOGEN TYPE

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 and never touch the glass portion. Dust, moisture, etc. entering the headlight may mal-affect its performance. Therefore, never leave the headlight without a bulb for extended periods of time.

HID TYPE

CAUTIONDo not operate with wet hands. As the lightening circuit uses high voltage, be sure to confirm that the power supply is turned off before working on it. When replacing the bulb, hold the flange portion and 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.

  3. If NG, replace the bulb with a new one.
CAUTIONDo not operate 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 the power supply is connected to the connector on the vehicle's side.
  1. Check the bulb specification. SPECIFICATION GENERAL DESCRIPTION. >
  2. Install a specified HID bulb for headlight lighting test.
  3. If the headlight does not illuminate, replace the bulb with a new one.
  4. Check the HID ballast. Check the ballast in the following methods and judge if it can be reused or not. Perform the cold start (turning on the lights after the headlights is gone off for more than 10 minutes) and hot start (turning on the headlights for more than 15 minutes --> turning off the lights for one minute --> turning on the lights again) several times and check if the headlights are lit surely. Check the lighting condition from immediately after the cold start until the stable condition (approx. 5 min.), to make sure that the unstable condition (flicker etc.) does not occur. Attach the two bulbs having been used for the same period of time to the right and left headlights and keep the headlights for approx. 30 minutes lit. Check the difference of brightness between right and left headlights.
  5. If NG, replace the ballast with a new one.
