RELAY ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT HEATER RELAY


    1. for PTC heater 600W type


      1. A00YAO6N13
        A00Y9QBN13

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        3 - 5 Battery voltage is not applied between terminals 1 and 2 10 kΩ or higher
        3 - 5 Battery voltage is applied between terminals 1 and 2 Below 1 Ω

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

    2. A00YAO6N12

      for PTC heater 495W type


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        3 - 5 Battery voltage is not applied between terminals 1 and 2 10 kΩ or higher
        3 - 5 Battery voltage is applied between terminals 1 and 2 Below 1 Ω

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