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

        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        8 - 6 OFF 10 kΩ or higher
        8 - 6 ON 350 Ω to 3.4 kΩ
        8 - 3 ON Below 1 Ω

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

    2. Check that the LED illuminates.
