What ATC 121 Means On a Case IH tractor, fault code ATC 121 is related to the ATC climate control controller. The official description is: Temperature select pot open/shorted to power. In practical terms, the ATC controller is detecting an electrical problem in the temperature selection input circuit. The temperature select potentiometer, often called a…
What ATC 120 Means On a Case IH tractor, fault code ATC 120 is related to the ATC climate control controller. The official description is: Blower speed select pot open/shorted to power. In practical terms, the ATC controller is detecting an electrical problem in the blower speed selection input circuit. The signal from the blower…
What ATC 118 Means On a Case IH tractor, fault code ATC 118 is a climate control fault from the ATC controller. The official description is: Outside air sensor shorted to ground. In practical terms, the ATC controller is seeing an electrical condition that suggests the outside air temperature sensor circuit is connected to ground…
Fault code ATC 117 on a Case IH tractor relates to the ATC climate control system. The official description is: Outside air sensor open or shorted to power. This means the ATC controller is detecting an electrical problem in the outside air temperature sensor circuit. The circuit may be open, meaning the controller is not…
What ATC 116 Means ATC 116 is a Case IH tractor climate control fault code from the ATC controller. The official description is: Evaporator sensor shorted to ground. In practical terms, the ATC controller is detecting an electrical condition in the evaporator sensor circuit that looks like the signal is being pulled to ground. This…
What Does Case IH ATC 115 Mean? On a Case IH tractor, fault code ATC 115 is related to the ATC climate control controller. The official description is: Evaporator sensor open or shorted to power. In practical terms, the ATC controller is detecting an electrical problem in the evaporator sensor circuit. The circuit may be…
What ATC 113 Means On a Case IH tractor with an ATC climate control controller, fault code ATC 113 means: Outlet sensor open or shorted to power. In practical terms, the ATC controller has detected an electrical problem in the outlet sensor circuit. The circuit may be open, meaning the controller cannot read the sensor…
What ATC 112 Means On a Case IH tractor, fault code ATC 112 is related to the ATC climate control controller. The official description is: Cab sensor shorted to ground. In practical terms, the ATC controller is detecting that the cab sensor circuit is pulled to ground when it should not be. This may indicate…
What ATC 111 Means On a Case IH tractor, fault code ATC 111 relates to the ATC climate control controller. The official description is: Cab sensor open or shorted to power. In practical terms, the ATC controller has detected an electrical problem in the cab sensor circuit. The circuit may be open, meaning the controller…
What ATC 114 Means ATC 114 is a Case IH tractor fault code from the ATC climate control controller. The official description is: Outlet sensor shorted to ground. In practical terms, the ATC controller has detected an electrical condition suggesting that the outlet temperature sensor circuit is connected to ground when it should not be….
