Electrical & Sensor Issues

• Battery Voltage Too Low or High 

•  Throttle Position Sensor Not Responding

• Engine Oil Temperature Too High

• Fuel Temperature Too Low

• Vehicle Speed Signal Lost

Emissions & Aftertreatment (if supported by ECM)

• EGR Valve Not Calibrated

• DPF Soot Level Too High

• Aftertreatment System Fault

• Aftertreatment Inlet Temp Too Low

• DEF Pressure Too Low (if DEF is used on the model)

General Communication & Sensor Failures

Engine Performance

• Engine Speed (RPM): Keep track of engine revolutions per minute to assess load and performance.

• Coolant Temperature: Monitor coolant levels to prevent overheating and detect cooling system faults.

• Oil Pressure: View real-time oil pressure to ensure proper engine lubrication.

• Fuel Rate: Measure fuel consumption to optimize efficiency and detect irregularities.

• Boost Pressure: Check turbocharger performance through intake manifold pressure readings.

• Intake Manifold Temperature: Track air intake temperatures for efficient combustion.

• Throttle Position: See how much throttle is applied—useful for diagnosing acceleration or power issues

Vehicle and System Status

• Battery Voltage: Monitor the electrical system’s health with live voltage readings.

• Engine Hours: Track total operating hours for accurate service and maintenance scheduling.

• Fuel Level: View remaining fuel percentage (when supported by the machine).

• Transmission Gear Position: See current gear selection (available on supported models).

• Vehicle Speed: Monitor ground speed data for operational diagnostics.

Emissions & Diagnostics

• EGR Valve Position: Monitor exhaust gas recirculation system to diagnose emissions-related issues (if supported).

• Turbocharger Speed: Keep tabs on turbocharger performance on compatible equipment.

• Diagnostic Trouble Codes (DTCs): View active and logged fault codes instantly, with descriptions to pinpoint issues—such as high coolant temperature or low oil pressure.
