    GTY370366Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    *a Component without harness connected
    (Seat Heater Switch LH)
    1. Check the resistance.
      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Switch Condition Specified Condition
        2 (IG) - 3 (HI) HI position on Below 1 Ω
        1 (LO) - 6 (E) Below 1 Ω
        2 (IG) - 1 (LO) LO position on Below 1 Ω

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

    2. Inspect the indicator operation.
      1. Apply battery voltage to the seat heater switch LH connector, and check that the seat heater switch LH indicator LED illuminates.

        OK

        Measurement Condition Switch Condition Specified Condition
        Battery positive (+) → 2 (IG)
        Battery negative (-) → 6 (E)        		 HI position on HI indicator LED illuminates
        Battery positive (+) → 2 (IG)
        Battery negative (-) → 6 (E)        		 LO position on LO indicator LED illuminates

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

    3. Inspect the illumination operation.
      1. Apply battery voltage to the seat heater switch LH connector, and check that the seat heater switch LH LED illuminates.

        OK

        Measurement Condition Specified Condition
        Battery positive (+) → 4 (ILL+)
        Battery negative (-) → 5 (ILL-)        		 LED illuminates

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

  2. INSPECT SEAT HEATER SWITCH RH

    *a Component without harness connected
    (Seat Heater Switch RH)
    1. Check the resistance.
      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Switch Condition Specified Condition
        3 (IG) - 4 (HI) HI position on Below 1 Ω
        2 (LO) - 10 (E) Below 1 Ω
        3 (IG) - 2 (LO) LO position on Below 1 Ω

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

    2. Inspect the indicator operation.
      1. Apply battery voltage to the seat heater switch RH connector, and check that the seat heater switch RH indicator LED illuminates.

        OK

        Measurement Condition Switch Condition Specified Condition
        Battery positive (+) → 3 (IG)
        Battery negative (-) → 10 (E)        		 HI position on HI indicator LED illuminates
        Battery positive (+) → 3 (IG)
        Battery negative (-) → 10 (E)        		 LO position on LO indicator LED illuminates

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

    3. Inspect the illumination operation.
      1. Apply battery voltage to the seat heater switch RH connector, and check that the seat heater switch RH LED illuminates.

        OK

        Measurement Condition Specified Condition
        Battery positive (+) → 6 (ILL+)
        Battery negative (-) → 8 (ILL-)        		 LED illuminates

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