HEATER SWITCH INSPECTION

PROCEDURE


  1. INSPECT IDLE UP SWITCH


    1. B003N32C01
      *a

      Component without harness connected

      (Idle Up Switch)

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      3 - 6 Idle up switch ON position Below 10 Ω
      Idle up switch OFF position 10 kΩ or higher

      If the result is not as specified, replace the idle up switch.

    2. B003N32C04
      *a

      Component without harness connected

      (Idle Up Switch)

      Check that the illumination.


      1. Apply battery voltage to the connector terminal and check the illumination.

        OK
        Measurement Condition Specified Condition

        Battery positive (+) → 5 (ILL+)

        Battery negative (-) → 4 (ILL-)

        		 Idle up switch illuminates

        If the result is not as specified, replace the idle up switch.

  2. INSPECT HEATER SWITCH ASSEMBLY


    1. B003RG6C04
      *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
      1 (IN) - 5 (E) Heater switch assembly ON position Below 10 Ω
      Heater switch assembly OFF position 10 kΩ or higher

      If the result is not as specified, replace the heater switch assembly.

    2. B003QK5C04
      *a

      Component without harness connected

      (Heater Switch Assembly)
      *b Indicator

      Check that the Indicator.


      1. Apply battery voltage to the connector terminal and check the Indicator.

        OK
        Measurement Condition Switch Condition Specified Condition

        Battery positive (+) → 4 (IG)

        Battery negative (-) → 5 (E)

        		 Heater switch assembly ON position Indicator illuminates

        If the result is not as specified, replace the heater switch assembly.

    3. B003RG6C05
      *a

      Component without harness connected

      (Heater Switch Assembly)

      Check that the illumination.


      1. Apply battery voltage to the connector terminal and check the illumination.

        OK
        Measurement Condition Specified Condition

        Battery positive (+) → 3 (ILL+)

        Battery negative (-) → 2 (ILL-)

        		 Heater switch assembly illuminates

        If the result is not as specified, replace the heater switch assembly.
