AUTOMATIC HEADLIGHT BEAM LEVEL CONTROL SYSTEM INITIALIZATION

Note


  • If the headlight ECU sub-assembly LH has been replaced, it is the necessary synchronize the vehicle information and perform Headlight ECU Sub-assembly LH Initialization. After synchronizing vehicle information, perform Headlight ECU Sub-assembly LH Initialization.

  • Initialize the headlight ECU sub-assembly LH (set the zero point of the height control sensor in the headlight ECU sub-assembly LH) after the vehicle height changes due to replacement of suspension components.

  • Adjust the headlight aim after initializing the headlight ECU sub-assembly LH.


  1. SYNCHRONIZE VEHICLE INFORMATION


    1. When using the GTS:


      1. Turn the power switch off.

      2. Connect the GTS to the DLC3.

      3. Turn the power switch on (IG), and check that the "Headlight System Uninitialized Visit Your Dealer" on the multi-information display continuously blink at 0.5 Hz.

      4. Enter the following menus: Body Electrical / AFS / Utility / ECU Information Sync.

      5. Check the display on the GTS and press "Next".

      6. Check that the "Headlight System Uninitialized Visit Your Dealer" on the multi-information display continuously blink 6 times at 2 Hz.

      7. Press "Exit" and turn the power switch off.

        Note

        After synchronizing the vehicle information, initialize the headlight ECU sub-assembly LH.

    2. When not using the GTS:


      1. Turn the power switch on (IG), and check that the "Headlight System Uninitialized Visit Your Dealer" on the multi-information display continuously blink at 0.5 Hz.

      2. Using the light control switch, turn the low beam headlights on and off 8 times within 20 seconds after turning the power switch on (IG).

        Note


        • If the low beam headlights or clearance lights turn on when the power switch is turned on (IG) on a vehicle without the light control switch OFF position, shine a light on the automatic light control sensor to change the vehicle to daytime mode.

        • Turn the low beam headlights on and off at intervals of less than 2 seconds.

        Tech Tips

        If this step cannot be completed within 20 seconds, turn the power switch off. Then, turn the power switch on (IG) and restart the procedure.

      3. Check that the "Headlight System Uninitialized Visit Your Dealer" on the multi-information display continuously blink 6 times at 2 Hz.

        Tech Tips


        • If "Headlight System Uninitialized Visit Your Dealer" on the multi-information display does not stop continuously blinking 6 times at 2 Hz, perform the procedure again from the beginning.

        • If "Headlight System Uninitialized Visit Your Dealer" on the multi-information display stops blinking and remains illuminated, the headlight ECU sub-assembly or rear height control sensor sub-assembly may be malfunctioning.

      4. Turn the power switch off.

        Note

        After synchronizing the vehicle information, initialize the headlight ECU sub-assembly LH.

  2. HEADLIGHT ECU SUB-ASSEMBLY LH INITIALIZATION


    1. Prepare vehicle for initialization


      1. Unload the trunk and vehicle, ensuring 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.

    2. Check the "Headlight System Malfunction Visit Your Dealer" on the multi-information display.


      1. Turn the power switch on (IG), and check the condition of the "Headlight System Malfunction Visit Your Dealer" on the multi-information display.

      2. Initialization (When using the GTS)
