This diagnostic trouble code (DTC) UIC 001713.16 is generated when the filter alarm level 2 switch at the hydraulic oil filter closes for more than three seconds at a transmission oil temperature above 28 °C (82 °F) and an engine speed of more than 700 rpm. The switch closes at a differential filter pressure of…

This diagnostic trouble code (DTC) UIC 001713.15 is generated when the filter alarm level 1 switch at the hydraulic oil filter closes for more than three seconds at a transmission oil temperature above 28 °C (82 °F) and an engine speed of more than 700 rpm. The switch closes at a differential filter pressure of…

This information for the operator (DTC) UIC 001504.31 is triggered if the reverse drive lever position “power zero” is activated for longer than 30 seconds without any valid signal indicating that the operator is present (operator on seat, clutch, or brake pedals depressed).

This diagnostic trouble code (DTC) UIC 001504.30 is triggered if the control unit receives a signal from the operator presence switch (S40, lead 6087) without interruption for 20 hours. This indicates a short in the signal lead.

This diagnostic trouble code (DTC) UIC 001079.04 is generated when less than 4.5 volts are measured at the positive power supply lead 6033 for 5-volt components (potentiometers for brake pedal, clutch pedal, speed control lever, accelerator pedal, and hand throttle) over a period of more than one second. This indicates a short to ground.

This diagnostic trouble code (DTC) UIC 001079.03 is generated when more than 5.5 volts are measured at the positive power supply lead 6033 for 5-volt components (potentiometers for brake pedal, clutch pedal, speed control lever, accelerator pedal, and hand throttle) over a period of more than one second. This indicates a shorted circuit.

This diagnostic trouble code (DTC) UIC 001079.02 is triggered if the control unit detects several incorrect output signals from the 5-volt components (potentiometers for brake pedal, clutch pedal, speed control lever, accelerator pedal, and hand throttle). This indicates a problem in the 5-volt power supply. If diagnostic trouble code UIC 001079.03 or UIC 001079.04 is…

This diagnostic trouble code (DTC) UIC 000974.04 is generated when the control unit measures a voltage of less than 0.5 volts at the signal input from channel 1 of the hand throttle potentiometer (B78, lead 6077). This indicates a problem at the signal lead or an issue with the potentiometer supply voltage.

This diagnostic trouble code (DTC) UIC 000974.03 is generated when the control unit measures a voltage of more than 4.5 volts at the signal input from channel 1 of the hand throttle potentiometer (B78, lead 6077). This indicates a problem either at the signal lead or at the potentiometer ground connection.

This diagnostic trouble code (DTC) UIC 000974.02 is triggered when the control unit detects a mismatch between the output signals of the hand throttle potentiometer (B78). The voltage at channel 1 (lead 6077) must be double the voltage of channel 2 (lead 6036).
