ADAPTIVE HIGH BEAM SYSTEM FREEZE FRAME DATA


  1. FREEZE FRAME DATA


    1. Whenever an adaptive high beam system DTC is stored, the headlight control computer assembly LH stores the current vehicle state as freeze frame data.

  2. CHECK FREEZE FRAME DATA


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / AFS / Trouble Codes.

    5. Select a DTC to display its freeze frame data.
