If you have previously purchased the PACCAR Davie4 diagnostic software and your initial license has expired, you will need to purchase a 12-month renewal. This purchase will re-activate your license for another 12-months. Please note that this does take 1-2 business days to process with PACCAR.

If you are looking to purchase Davie4 software for the first time, you can purchase it stand-alone, in a laptop kit, or a mutli-brand diagnostic tool.

Limited Time Offer

For a limited time, if you renew your PACCAR Davie 4 diagnostic software you will receive a free CF30 Panasonic Toughbook. (This laptop is refurbished with Windows 7 and will not be eligible for warranty.)
