LAUNCH Millennium HD ProA Diagnostic Tools

Check the Whole Truck, Not Just the Engine.

Scan supported electronic systems across the vehicle to see which modules contain faults. Read and clear DTCs, review live data, and enter available systems for a closer look before deciding the next step.

Cover More Commercial Vehicles.

Diagnostic coverage for more than 50 commercial vehicle brands helps users work across a wider range of trucks. The included 6-pin and 9-pin adapters support common heavy-duty diagnostic connections.

Start a Supported DPF Regeneration.

Initiate DPF regeneration on applicable vehicles when soot loading and vehicle conditions allow. This helps restore exhaust flow after the underlying cause of the regeneration issue has been addressed.

Code Replacement Injectors Correctly.

Enter injector calibration codes after supported injector replacement procedures. This allows the engine control module to recognize the installed injector and apply the correct fuel-delivery calibration.

Restore Clutch Operation After Service.

Perform clutch relearning on supported vehicles after clutch or transmission-related service. The procedure helps the control system relearn clutch position and engagement parameters.

Access Essential HD-OBD Data.

Use HD-OBD functions to retrieve supported heavy-duty fault codes and operating data. Quickly investigate warning lights and determine whether the truck requires immediate repair or further diagnosis.

Document and Share the Diagnosis.

Create diagnostic reports containing vehicle information, scanned systems, and detected fault codes. Save or share the results with a repair shop, fleet manager, or customer to provide a clearer record of the vehicle’s condition.

Vehicle coverage and the availability of system diagnostics, DPF regeneration, injector coding, clutch relearning, HD-OBD data, and reporting functions vary by make, model, year, and software coverage.
