• construction machinery
• other

Key Features:

• DPF Regeneration: Enables regeneration of the Diesel Particulate Filter (DPF), which is crucial for maintaining optimal engine performance and reducing exhaust emissions.

• Injector Coding: Ensures precision through injector coding – a critical process in calibrating fuel injection systems.

• MIL Reset: Resets the Malfunction Indicator Light (MIL) after repairs or maintenance, ensuring accurate fault monitoring.

• Maintenance Confirmation: Confirms that maintenance tasks have been completed, making it easier to keep records and maintain your vehicle.

• Injection Quantity Adjustment: Allows you to precisely tune the injection quantity for best engine performance and efficiency.

• Particulate Filter Change Counter Reset: Resets the particulate filter change counter, which is important for meeting emission standards.

• Differential Pressure Sensor Reset: Allows you to reset the differential pressure sensor to ensure proper operation.

• Pressure Relief Valve Reset: The pressure relief valve reset helps maintain the integrity of the fuel system.

• AdBlue System Bleeding: Allows bleeding of the AdBlue system, which is crucial for emission control systems.

• VGT Actuator Installation and Calibration: Ensures precise calibration of electronic variable geometry turbocharger (VGT) actuators.

• Reset Trip: Resets trip data, allowing you to monitor vehicle performance at specific time intervals.

• SCR Performance Test While Stationary: Allows you to perform Selective Catalytic Reduction (SCR) performance tests while the vehicle is stationary.

• DPF Ash Accumulator Reset: Resets the ash counter in the DPF for accurate monitoring and maintenance.

• 13 Special Functions: Offers a wide range of special functions such as idle speed adjustment, speed limiter setup, cruise control calibration and much more.

• Accurate Calibrations: Allows you to precisely tune key parameters such as idle speed, speed limits and various vehicle systems for optimal performance
