PACCAR Davie4 is the software used by dealerships and large fleets across North America. This is the same software as used by dealerships, which allows you to perform dealer level diagnostic commands such as:

DPF Regenerations
Injector/Cylinder tests
DPF & SCR Derate Disable
Download log files into PDF or Excel
Print and reset trip data

... and thousands more.


This software does NOT include access to the PACCAR ePortal for repair information. That is another subscription. This tool also requires Internet access to use, as you will be provided an unique username and password when using this software. This software is for the PACCAR MX engines only. For PX engines you can use Cummins Insite, aftermarket software, or a multi-brand diagnostic tool. This software will only work for 12-months, and then requires the you purchase a license renewal. This software also takes 2-4 business days to be delivered due to processing at PACCAR.

Minimum System Requirements:

  • Windows 7 or 10 Professional Version
  • 3 GB free hard drive space
  • 4 GB of RAM
  • A USB LINK 2 is the recommended adapter, most others will not work with PACCAR software.
