    *a Battery
    *b Ohmmeter

    1. Check the resistance.


      1. Using an ohmmeter, measure the resistance between the terminals.

        Standard resistance
        Tester Connection Specified Condition
        3 - 5 10 kΩ or higher
        3 - 5

        Below 1 Ω

        (When battery voltage applied to terminals 1 and 2)

        If the result is not as specified, replace the PTC heater relay.
