This error code, EPC 001713.15, is generated when the filter alarm level 1 switch at the hydraulic oil filter was closed for more than three seconds at a hydraulic oil temperature above 28°C (82°F) and an engine speed above 700 rpm. The switch closes at a differential filter pressure of 350 kPa (3.5 bar; 51…

This error code, EPC 001079.04, is generated when the EPC measures less than 4.8 volts at the positive lead of the power supply to the 5-volt components (clutch pedal potentiometer B65, accelerator pedal potentiometer B79, hand throttle potentiometer B96, and enable pressure sensor B105). This indicates a short to ground in the circuit.

This error code, EPC 001079.03, is generated when the EPC measures more than 5.2 volts at the positive lead of the power supply to the 5-volt components (clutch pedal potentiometer B65, accelerator pedal potentiometer B79, hand throttle potentiometer B96, and enable pressure sensor B105). This indicates that the circuit is shorted to a positive supply…

This error code, EPC 001079.02, is generated when the control unit detects several incorrect output signals from the 5-volt components (clutch pedal potentiometer B65, accelerator pedal potentiometer B79, hand throttle potentiometer B96, and enable pressure sensor B105). This indicates a problem with the 5-volt power supply.

This error code, EPC 000974.03, is generated when the control unit measures a voltage in excess of 4.7 volts at the signal input of the hand throttle potentiometer (B96, lead 6018). This indicates a short to a positive lead, an open circuit, or a problem with the ground connection in the potentiometer’s circuit.
