RELAY ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT HEATER RELAY


    1. A004JD5

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

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

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

  2. INSPECT HEATER BLOWER MOTOR RELAY ASSEMBLY


    1. A004K7V

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3 - 4 Battery voltage not applied Below 1 Ω
      3 - 4 Battery voltage applied to terminals 1 and 2 10 kΩ or higher
      3 - 5 Battery voltage not applied 10 kΩ or higher
      3 - 5 Battery voltage applied to terminals 1 and 2 Below 1 Ω

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