PROCEDURE

  1. INSPECT LIGHT CONTROL RHEOSTAT

    E271210C01

    *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.

    2. E271210C02

      *1

      Knob

      *a

      Component without harness connected

      (Light Control Rheostat)

      Inspect the TAIL cancel switch.

      Tip:

      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.
