1. INSPECT PTC HEATER RELAY


    E183912E01

  1. Check the resistance. (for Type A:)

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

      Standard Resistance:
      Tester Connection
      		Condition
      		Specified Condition
      3 - 5
      		When battery voltage not applied
      		10 kΩ or higher
      3 - 5
      		When battery voltage to terminals 1 and 2
      		Below 1 Ω

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



    E109076E01

  1. Check the resistance. (for Type B:)

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

      Standard Resistance:
      Tester Connection
      		Condition
      		Specified Condition
      3 - 5
      		When battery voltage not applied
      		10 kΩ or higher
      3 - 5
      		When battery voltage to terminals 1 and 2

    *1
    		Component without harness connected:
    (Integration Relay)

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

      Standard Resistance:
      Tester Connection
      		Condition
      		Specified Condition
      D6 - F9
      		When battery voltage not applied
