PACCAR Davie4 Diagnostic Software License (Initial Purchase)
This software does NOT include access to the PACCAR ePortal for repair information. That is another subscription. This tool requires Internet access to use, and is intended for 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 purchase of a PACCAR Davie4 Renewal license. This software also takes 2-4 business days to be delivered due to processing at PACCAR.
