This error code, EPC 524029.03, is generated when the control unit measures a voltage of more than 4.7 volts at the signal input from channel 1 of the clutch pedal potentiometer (B65, lead 6114). This indicates a problem at the signal lead or at the potentiometer ground connection.

This error code, EPC 524029.02, is generated when the control unit detects a mismatch between the output signals of the clutch pedal potentiometer (B65). The voltage at channel 1 (lead 6114) must be double the voltage of channel 2 (lead 6007). This indicates a potential issue with the clutch pedal potentiometer or its circuitry.

This error code, EPC 524025.31, is generated when the control unit receives an incorrect switch signal combination from the reverse drive lever, indicating that the not-neutral switch is closed while the forward or reverse switch is open. This suggests a potential issue with the switch signals or an incorrect lever position.

This error code, EPC 524024.31, is generated when the control unit receives an incorrect switch signal combination from the reverse drive lever, indicating that both the forward and reverse switches are actuated at the same time. This could be due to a switch malfunction or an issue with the wiring.

This error code, EPC 524023.31, is generated when the control unit receives an incorrect switch signal combination from the reverse drive lever. Specifically, it indicates that the forward or reverse switch is closed while the not-neutral switch is open, suggesting a potential issue with the switch signals or an incorrect lever position.

This operator information (diagnostic trouble code), EPC 524020.31, is generated when the EPC control unit detects an active forward, reverse, or not-neutral switch during the starting procedure. This indicates that the reverse drive lever is not in the neutral position during startup, which may be due to operator error or a malfunctioning switch.

This error code, EPC 523969.11, is generated when the EPC control unit detects an activated gear selector switch (upshift or downshift) during the starting procedure. This indicates that the gear selector switch is not in the correct position during startup, which could be due to a faulty switch or an operator error.

This operator information (diagnostic trouble code), EPC 523966.31, is generated when the comehome mode is activated (K07/04 or K03/04 connector for comehome feature in “COME HOME” position). The comehome mode can only be activated within the first 2.5 seconds after starting the engine when the connector for the comehome feature is in “COME HOME” position…

This operator information (diagnostic trouble code), EPC 523961.07, is generated when the EPC control unit detects an active signal from the park lock switch (range shift lever in park position) while the reverse drive lever is not in neutral position. This can also occur when the operator moves the reverse drive lever to the forward…

This operator information (diagnostic trouble code), EPC 523677.31, is generated when the declutch switch on the range shift lever has been actuated, but there is no valid signal to indicate that the operator is present (operator on seat, clutch, or brake pedals depressed). A valid signal indicating the operator’s presence must be received at least…

This error code, EPC 523677.14, is generated if a range shift lever with a declutch switch is equipped (diagnostic address EPC168 set to “1”) and the EPC control unit detects that the declutch switch is deactivated (diagnostic address EPC167 set to “0”). This diagnostic trouble code can also occur as a subsequent fault in connection…
