This diagnostic trouble code (DTC) is generated when the control software detects that the left brake pedal sensor unit indicates over 2 volts when the brake pedal switch is closed, or less than 1.1 volts when the brake pedal switch is open.

This diagnostic trouble code (DTC) is generated when the control software receives an incorrect combination of signals for the position of the reverse drive lever over an extended period. It can also be triggered if the reverse drive lever is held in an intermediate position for too long. Diagnosis is required only if this code…

This diagnostic trouble code (DTC) is generated when the control software receives an incorrect combination of signals for the position of the reverse drive lever. This indicates that multiple positions of the lever are being detected simultaneously, which is not possible under normal operation.
- John Deere error TIA codes
This diagnostic trouble code (DTC) is generated when there is a data transfer problem between the PTA control software and the PDU control software. The reception of messages sent on the CAN Bus by the PDU control software is intermittent or non-existent, indicating a potential open circuit, short circuit, or faulty CAN Bus terminating resistors.

This diagnostic trouble code (DTC) is generated when there is a data transfer problem between the PTA control software and the TIA control software. The reception of messages sent on the CAN Bus by the control software is intermittent or non-existent, indicating a potential open circuit, short circuit, or faulty CAN Bus terminating resistors.
- John Deere error TIA codes
This diagnostic trouble code (DTC) is generated when the TIA control software detects a deviation of more than 100 rpm between the engine speed and transmission input speed for at least 5 seconds. This indicates a potential problem with a speed sensor or its associated circuit.

This diagnostic trouble code (DTC) is generated when there is a data transfer problem between the ECU control software and the TIA control software. This can occur if the reception of messages sent on the CAN BUS by the ECU control software is intermittent or non-existent, indicating a potential open circuit, short circuit, or faulty…
- John Deere error TIA codes
This diagnostic trouble code (DTC) is generated if the reverse drive lever position “Power Zero” is activated for longer than 30 seconds without a valid signal indicating operator presence (such as the operator being on the seat, or the clutch or brake pedals being depressed).
- John Deere error TIA codes
This diagnostic trouble code (DTC) is generated when the control software measures a voltage of less than 0.5 V at the signal input from channel 1 of the hand throttle potentiometer. This low voltage reading indicates a potential problem with the signal lead or the supply voltage to the potentiometer.
