The error code, ATC 524203.04, is triggered when the control unit measures 0 volts at the signal input for the front ambient air temperature sensor (B125, lead 2001). This absence of voltage typically indicates a short to ground in the circuit, which can prevent the sensor from functioning and delivering accurate temperature readings.

The error code, ATC 524203.03, is triggered when the control unit measures a voltage exceeding 5 volts at the signal input for the front ambient air temperature sensor (B125, lead 2001). This high voltage typically indicates that the circuit is either shorted to a supply lead or is open. Such an electrical fault can lead…

The error code, ATC 524202.04, is triggered when the control unit measures 0 volts at the signal input for the rear ambient air temperature sensor (B126, lead 2006). This absence of voltage typically indicates a short to ground in the circuit, which can prevent the sensor from functioning and delivering accurate temperature readings.

The error code, ATC 523979.07, is triggered when the control unit receives the engagement signal from the heated rear window switch (S139, lead 2013) for an extended period of time. This condition usually suggests that the switch is either jammed or defective, or there is an underlying issue in the circuit such as a stuck…

The error code, ATC 523848.13, is triggered when the air distribution adjusting motor (B132) is found to have an invalid calibration or is not yet calibrated. This lack of proper calibration can lead to incorrect air flow distribution within the cabin, affecting the HVAC system’s ability to effectively control cabin climate.

The error code, ATC 523979.05, is triggered when the control unit detects too low an amperage at the signal input of the indicator light in the heated rear window switch (S139, lead 2021). This condition often indicates an interruption in the circuit. For tractors without the optional heated rear window, this error might occur due…

The error code, ATC 523848.07, is triggered when the control unit receives a valid position signal from the potentiometer of the air distribution adjusting motor (B132), but the motor cannot move to its desired position. This discrepancy often points to a mechanical fault within the air distribution system or an open line in the motor’s…

The error code, ATC 523848.06, is triggered when the control unit detects an excessively high amperage at the adjusting motor connecting leads 2028 and/or 2029, which control the air distribution flaps. This high current condition often indicates a short to ground in the circuit, which can cause overheating and potential damage to the adjusting motor…

The error code, ATC 523848.05, is triggered when the control unit measures an unusually low amperage at the adjusting motor connecting leads 2028 and/or 2029, which control the air distribution flaps. This low current condition typically indicates a possible short in the circuit, which can hinder the motor’s ability to adjust the air distribution flaps…

The error code, ATC 523848.04, is triggered when the control unit measures 0 volts at the signal input for the potentiometer, which is associated with the adjusting motor (B132) for air distribution (lead 2017). This lack of voltage typically indicates a short to ground in the circuit, potentially preventing the adjusting motor from correctly positioning…
