The HD7000 reads full-system codes and does parked DPF regen, idle/speed-limit, and service resets from the cab — on everything from a 6.7 Cummins/Power Stroke/Duramax pickup to Class-8 trucks (Detroit, Paccar, CAT, Volvo, Mack, International).

Frequently Asked Questions
What does P2263 mean on a Hino?
P2263 means Turbo/Super Charger Boost System Performance. Boost pressure is not tracking what the control module commands across operating conditions.
Is P2263 a Hino-specific code?
No. P2263 is a generic OBD-II code defined by SAE J2012, so it means the same thing on any vehicle that sets it. The exact conditions Hino uses to set it on its diesels are in Hino service information.
