What ATC 128 Means On a Case IH tractor, fault code ATC 128 is a climate-control fault from the ATC controller. The official description is: High pressure switch (-) input shorted to ground. In practical terms, the ATC controller is detecting that the negative-side input circuit for the high pressure switch is grounded when it…
Fault code ATC 127 on a Case IH tractor relates to the ATC climate control controller. The official description is: High pressure switch (-) input shorted to power. In practical terms, the ATC controller is detecting voltage where it does not expect it on the negative input side of the high pressure switch circuit. This…
What ATC 126 Means On a Case IH tractor, fault code ATC 126 is a climate control system fault from the ATC controller. The official description is: High pressure switch (+) input shorted to ground. In practical terms, the ATC controller is detecting that the positive input circuit for the high pressure switch is being…
What ATC 125 Means On a Case IH tractor, fault code ATC 125 is logged by the ATC climate control controller. The official description is: High pressure switch (+) input shorted to power. In practical terms, the ATC controller is seeing an electrical condition on the high pressure switch positive input circuit that suggests the…
What Case IH ATC 122 Means Fault code ATC 122 on a Case IH tractor relates to the ATC climate control controller. The official description is: Mode Select Pot Open Or Shorted To Power. In practical terms, the ATC controller is detecting an electrical problem with the mode select potentiometer circuit. The mode select potentiometer…
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…
