1. INSPECT HEADLIGHT LEVELING SWITCH


  1. Voltage Ratio Inspection.

    1. Disconnect connector H135 from the headlight leveling switch.



      2. E212430E01

    2. 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.



      4. E212432E01

    4. 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

      HINT:
      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.
