LIGHT CONTROL RHEOSTAT INSPECTION

PROCEDURE


  1. INSPECT LIGHT CONTROL RHEOSTAT

    A00YS3GC01
    *1 Knob
    *a

    Component without harness connected

    (Light Control Rheostat)

    1. Inspect the light control rheostat.


      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        9 (T) - 6 (E) Always 10 +/-2 kΩ
        7 (TR) - 6 (E) Knob turned fully upward 10 +/-2 kΩ
        7 (TR) - 6 (E) Knob turned fully downward Below 50 Ω
        7 (TR) - 6 (E) Knob turned from fully upward to fully downward 10 +/-2 kΩ → Below 50 Ω

        If the result is not as specified, replace the light control rheostat.

      *1 Knob
      *a

      Component without harness connected

      (Light Control Rheostat)

      Inspect the TAIL cancel switch.

      Tech Tips

      The TAIL cancel switch is built into the light control rheostat.


      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        9 (T) - 8 (TC)

        Knob turned fully upward

        (TAIL cancel condition)

        		 10 kΩ or higher
        9 (T) - 8 (TC) Knob not turned fully upward Below 1 Ω

        If the result is not as specified, replace the light control rheostat.
