For Who Is This Device & Software?

  • Commercial Vehicle & Truck Workshops: Maximize the value of your HD IV multiplexer to read and configure commercial fleets, construction equipment, and heavy-duty diesel engines.
  • Independent Garages & Auto Repair Shops: Expand your repair capabilities by turning your heavy-duty module into a versatile system that can handle cars, EVs, and commercial trucks.
  • Mobile Diagnostics Specialists: Perform rapid, on-site heavy machinery or passenger vehicle troubleshooting and module configurations without carrying bulky equipment.

Wichtige Funktionen

  • Full-System Read / Clear DTCs: Deeply interrogates all available electronic control modules (including Engine, ABS, SRS/Airbag, Transmission, Body Control Module, HVAC, and specialized commercial fleet controllers) to read, translate, and erase manufacturer-specific diagnostic trouble codes.
  • Real-Time Live Data Streaming: Stream dynamic PID data values simultaneously. Monitor live misfires, DPF soot levels, sensor voltages, fuel trims, and fluid temperatures via real-time text or smooth graphical charts to isolate faults quickly.
  • Active Tests (Bi-Directional Control): Actively command vital vehicle electronics to isolate mechanical failures. Manually cycle the ABS pump, trigger radiator cooling fans, run cylinder cutout tests, test individual fuel injectors, or actuate the AC clutch instantly.
  • Service Reset Functions: Access an extensive library of routine maintenance procedures. The software supports essential resets such as Electronic Parking Brake (EPB) service mode, Oil Maintenance tracking, Steering Angle Sensor (SAS) zeroing, Battery Matching (BMS), Injector Coding, and forced DPF Regeneration.
  • ECU Coding & Adaptations: Supports variant coding, configuration adjustments, and component learning protocols following the installation of replacement parts or electronic modules on compatible vehicle makes.

App Connectivity & Activation

  • Wireless Mobility: Connects seamlessly over your hardware’s built-in Bluetooth / BLE link, providing stable wireless operation across a comfortable workshop radius without tethering cables.
  • Mobile App Integration: Tailored natively for Android-powered environments. The lightweight, intuitive Diagzone PRO app interface runs smoothly on standard Android smartphones or tablets (requires Android 7.0 or higher).
  • Instant Serial Number Activation: 100% digital fulfillment with zero physical shipping required. Simply provide your hardware’s unique 12-digit Serial Number upon checkout.
