RELAY ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT PTC HEATER RELAY


    1. Check the resistance.


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

        A001VM0C03
        *a

        Component without harness connected

        (PTC HTR NO. 1)

        		 *b

        Component without harness connected

        (PTC HTR NO. 2)
        *c

        Component without harness connected

        (PTC HTR NO. 3)

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

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