HEADLIGHT LEVELING SWITCH INSPECTION

PROCEDURE


  1. INSPECT HEADLIGHT LEVELING SWITCH


    1. Voltage Ratio Inspection.


      1. Disconnect connector H135 from the headlight leveling switch.

        Front side of wire harness connector

        (to Headlight Leveling Switch)

        Using SST, measure the voltage between terminals H135-5 (B) and H135-1 (E). (Voltage A)

      3. Connect connector H135 to the headlight leveling switch.

        Component with harness connected

        (Headlight Leveling Switch)

        Using SST, measure the voltage between terminals H135-2 (T) and H135-1 (E) from backside of the connector. (Voltage B)

      5. Divide Voltage B by Voltage A to obtain the voltage ratio.

        Standard Voltage Ratio
        Switch Position Voltage Ratio (%)
        0 7 to 13
        (0.5) 12.3 to 18.3
        1 17.7 to 23.7
        (1.5) 23.0 to 29.0
        2 28.3 to 34.3
        (2.5) 33.7 to 39.7
        3 39.0 to 45.0
        (3.5) 44.7 to 50.3
        4 49.7 to 55.7
        (4.5) 55.0 to 61.0
        5 60.3 to 66.3

        Tech Tips

        If Voltage A is 12 V and Voltage B is 10 V, the voltage ratio (10/12=0.83) will be 83.3%.

        If the result is not as specified, replace the headlight leveling switch.
