        A-1 - B-1 Below 1 Ω

        If the result is not as specified, replace the front seat cushion heater assembly LH.

      2. Check the thermostat resistance.

        Standard Resistance
        Tester Connection Condition Specified Condition
        A-4 - B-3 Thermostat temperature 42°C (108°F) 10 kΩ or higher
        A-2 - B-2 10 kΩ or higher

        If the result is not as specified, replace the front seat cushion heater assembly LH.
