This diagnostic trouble code is generated if one of the following situations arises: The power supply line, ground line, or signal line is open. The 5-volt power supply line is shorted to another (12 volts) power supply line. K07/02 alarm is used on tractors up to Serial Number Break 2008. K03/02 alarm is used on…

This diagnostic trouble code is generated when the control unit registers a supply voltage of less than 9 volts. Low supply voltage can affect the performance and reliability of the control unit.

This diagnostic trouble code is generated when there is a data transfer problem between the TCU (Transmission Control Unit) and PLC (Programmable Logic Controller). Reception of one, several, or all of the CAN messages transmitted by the TCU is intermittent or nonexistent. This could be due to a loose wire or other communication issues.

This diagnostic trouble code is generated when the control unit detects no current at the signal input to the park lock solenoid valve 2 (Y15/2). This indicates that the circuit is open.

This diagnostic trouble code is generated when the control unit detects that the current at the signal input to the park lock solenoid valve 2 (Y15/2) is too high or too low. This indicates that the circuit is shorted to ground or to positive.

This diagnostic trouble code is triggered when the control unit detects a voltage of less than 0.3 volts at the signal input for the park lock pressure sensor (B90). This indicates that the circuit is shorted to ground or is open.

This diagnostic trouble code is triggered when the control unit detects a voltage exceeding 4.8 volts at the signal input for the park lock pressure sensor (B90), indicating a short to a supply lead somewhere in the circuit.

This diagnostic trouble code is triggered when the control unit detects that the voltage at the signal input for the wheel speed sensor (B84) is too high, indicating a short to a supply lead or an open circuit.

This diagnostic trouble code is triggered when the control unit detects that the voltage at the signal input for the wheel speed sensor (B84) is too low, indicating a potential short to ground in the circuit.

READ MORE

This diagnostic trouble code is generated when the control unit detects a very high error rate in the CAN BUS messages related to the power train. This indicates a severe issue with the CAN BUS communication network.
