HEATER SWITCH INSPECTION

PROCEDURE


  1. INSPECT HEATER SWITCH ASSEMBLY


    1. Check resistance.


      1. B001CEFC01
        *a

        Component without harness connected

        (Heater Switch Assembly)

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

        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        5 (IG) - 2 (IN) Heater switch assembly off 10 kΩ or higher
        Heater switch assembly on Below 1 Ω

        If the result is not as specified, there may be a malfunction in the heater switch assembly.

    2. Check that the Indicator.


      1. B001FRSC01
        *a

        Component without harness connected

        (Heater Switch Assembly)
        *b Indicator

        Apply battery voltage to the connector and check the Indicator.

        OK
        Measurement Condition Specified Condition

        Battery positive (+) → 2 (IN)

        Battery negative (-) → 4 (E)

        		 Indicator illuminates

        If the result is not as specified, there may be a malfunction in the heater switch assembly.

    3. Check that the illumination.


      1. B001CEFC02
        *a

        Component without harness connected

        (Heater Switch Assembly)

        Apply battery voltage to the connector and check the illumination.

        OK
        Measurement Condition Specified Condition

        Battery positive (+) → 6 (ILL+)

        Battery negative (-) → 1 (ILL-)

        		 Heater switch assembly illuminates

        If the result is not as specified, there may be a malfunction in the heater switch assembly.

  2. INSPECT IDLE UP SWITCH

    B001FDAC03
    *a

    Component without harness connected

    (Idle Up Switch)

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      6 (SW) - 3 (E) Idle up switch off 10 kΩ or higher
      Idle up switch on Below 1 Ω

    2. Apply battery voltage to the connector and check the LED illumination.

      OK
      Measurement Condition Specified Condition

      Battery positive (+) → 5 (ILL+)

      Battery negative (-) → 4 (ILL-)

      		 LED illuminates

      If the result is not as specified, there may be a malfunction in the idle up switch.
