A $30 car code reader can't do diesel. 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).

Common Symptoms
- Yellow regen lamp on then red lamp
- Machine in derate / shutdown timer
Probable Causes (Ranked by Likelihood)
- DPF plugged with soot from short-duty / idle-heavy skid-steer use Very Likely
- Ash-loaded DPF past service interval (3,000-5,000 hr) Likely
- Injector leak dumping raw fuel into DPF Possible
Step-by-Step Diagnostic Procedure
Initiate parked regen via Service Analyzer (requires warm engine, fuel in tank, no faults).
Monitor DPF differential pressure during regen -- should drop from >10 kPa to <3 kPa.
If regen fails, remove DPF for professional cleaning/ash removal.
