  • ECT at previous DC is greater than 70°C (158°F)
  • IAT deviation is greater than 0°C (32°F)

    (IAT deviation is difference between IAT at key off previous DC and IAT at key on)

  • ECT deviation is greater than 40°C (104°F)

    (ECT deviation is difference between ECT at key off previous DC and ECT at key "ON")

  • IAT or ECT circuit fault not present
