This diagnostic trouble code (DTC) is generated when the control software measures a voltage of more than 4.5 V at the signal input from channel 1 of the hand throttle potentiometer. This high voltage reading indicates a potential problem with the signal lead or the ground connection of the potentiometer.

This diagnostic trouble code (DTC) is generated when the control software detects a mismatch between the output signals of the hand throttle potentiometer. The voltage at channel 1 must be double the voltage at channel 2. A discrepancy in this ratio indicates a problem with the potentiometer or its associated wiring.

This diagnostic trouble code (DTC) is generated when the control software receives too many incorrect CAN BUS messages or detects a general problem in the connection to the 500 kBd vehicle CAN BUS. A high error rate in CAN BUS communication can significantly impact vehicle performance.

This diagnostic trouble code (DTC) is generated when the control software detects that too much time has elapsed (watchdog timeout). The watchdog timer is a safety mechanism that resets the system if the software fails to respond within a specified time frame.

This diagnostic trouble code (DTC) is generated when an error occurs while reading the internal module (EEPROM) of the control software.

This diagnostic trouble code (DTC) provides information only and is generated when the control software detects that the engine speed is too high. The code indicates that it is necessary to reduce speed (ground speed) when there is no weight pushing from behind to account for the excessive speed.

This diagnostic trouble code (DTC) is generated when the switch position of the clutch pedal switch, as transmitted by the PTA control software via a CAN message, does not match the actual position of the clutch pedal, determined by the signal from the clutch pedal potentiometer.

This diagnostic trouble code (DTC) is generated when the TIA control software detects an incorrect setting or input in the tractor model address. This indicates that the control software is not configured correctly for the specific tractor model.

READ MORE

This diagnostic trouble code (DTC) is generated when the control software does not receive the vehicle identification number (VIN) from other control units, or receives it incorrectly. All active VIN participants must send the programmed VIN to the control software at regular intervals.

READ MORE

This diagnostic trouble code (DTC) is generated when the VIN security function fails to enable due to an internal problem. This typically indicates an incorrect reprogramming of the control software, preventing proper VIN security activation.

This diagnostic trouble code is generated when there is a mismatch in the Vehicle Identification Number (VIN) information from different control units or control software within the vehicle.
