AUTOMATIC HEADLIGHT BEAM LEVEL CONTROL SYSTEM INITIALIZATION


  1. HEIGHT CONTROL SENSOR SIGNAL INITIALIZATION (WHEN NOT USING GTS)

    Note


    • Initialize the height control sensor signal after the vehicle height changes due to replacement of the suspension or after performing such operations as removal and reinstallation or replacement of the rear height control sensor.

    • Initialization is also necessary when the headlight leveling ECU is replaced.

    • Adjust the headlight aim after initializing the headlight leveling ECU.

    • When a malfunction is detected in the automatic headlight beam level control system, the height control sensor signal initialization is impossible. Perform troubleshooting before initialization.

  2. 1. PREPARE VEHICLE FOR INITIALIZATION


    1. Unload the trunk and vehicle, and make sure that the spare tire, tools and jack are in their original positions.

    2. Check that there are no occupants in the vehicle.

    3. Turn off the headlights.

    4. Stop the vehicle on a level surface and keep the vehicle height unchanged.

  3. 2. CHECK WARNING LIGHT

    *1 Fuel Receiver Gauge (for TFT Display Type)

    Turn the low beam headlights on and off using the light control switch within 20 seconds after connecting the terminals.

    Tech Tips

    The number of times the low beam headlights need to be turned on and off is determined by the present fuel level as shown below.

    Fuel Level Number of Times to Turn Low Beam Headlights on and off
    Fuel level is within range A. 1
    Fuel level is within range B. 2
    Fuel level is within range C. 3
    Fuel level is within range D. 4
    Fuel level is within range E. 5

    Note


    • Turn the low beam headlights on and off at approximately 3-second intervals.

    • Be sure to operate the headlight dimmer switch from the outside of the vehicle.

  • Check the warning light.

  • 3. INITIALIZATION


    1. Turn the ignition switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch to ON and the GTS on.

    4. Enter the following menus: Body Electrical / HL AutoLeveling / Utility / Height Sensor Initialization / Next.

    5. Check what is displayed on the screen of the GTS and press "Next".

      Check the fuel level of the fuel receiver gauge in the combination meter. The appropriate position ID is determined by the present fuel level.

    • Fuel Level Position ID
    A EMPTY
    B 1/4 to over EMPTY
    C 1/2 to over 1/4
    D 3/4 to over 1/2
    E FULL to over 3/4

  • Enter the determined position ID into the GTS and press "Next".

    Tech Tips

    If the position ID has not been entered, "Next" cannot be pressed.

  • Check the warning light.

  • Press "Exit".

    Tech Tips


    • If the calculated vehicle height is not within the acceptable range, the rear height control sensor initialization will end as an abnormal termination, and the warning light will blink 6 times at 2 Hz continuously. Disconnect SST from the DLC3 and turn the ignition switch off. Then restart from "Check Warning Light".

    • If initialization cannot be finished normally, check the LVL terminal circuit (Click here ), or perform inspections and repairs according to "Problem Symptoms Table" Click here.
