RELAY ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT PTC HEATER RELAY


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

      B005L58C01
      *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.
