1.PERFORM ACTIVE TEST USING GTS (HEADLIGHT LEVELING MOTOR)

  1. Using the GTS, perform the Active Test (Click here).

    HL Auto Leveling (w/ Static Headlight Auto Leveling)
    Tester Display
    		Test Part
    		Control Range
    		Diagnostic Note
    HL Auto Leveling
    		This test activates the Leveling Motor of the LH and RH headlights. By activating the Leveling Motor, illumination direction of the headlights can be moved up/down.
    		Up, Down, Stop
    		Perform the Active Test with the vehicle stopped, the ignition switch ON and the low beam headlights on.
