# Best heavy duty and diesel truck scanners with DPF regen Source: https://codeandclear.com/best/best-heavy-duty-truck-scanner Publisher: Code & Clear. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://codeandclear.com/how-we-pick A car OBD2 scanner will not talk to most Class 4 to 8 trucks. Heavy duty trucks use 6-pin and 9-pin connectors and J1939 or J1708 protocols. The job most owner-operators need, a forced DPF regen, is engine-specific. Some tools here cover a mixed fleet of Cummins, Detroit, PACCAR, Caterpillar, Volvo, Mack and International. Others are built for one engine family. This guide compares seven listings on the facts that decide fit: which engines the listing names for DPF regen, which connectors and protocols it states, extra functions such as injector cutoff and speed limit settings, and what the listing says about updates. DPF regen support is never universal. One listing warns that regen may be unavailable on some newer Detroit-powered trucks. Match the listing's engine list to your truck before you buy. ## Picks ### 1.
