Service bulletin CB22-N-002

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

In some 2022MY Isuzu F-Series trucks, an optional Diesel Particulate Filter (DPF) Regeneration "Inhibit" Switch was installed by mistake instead of the DPF Regeneration "Force" Switch. As a result, the vehicle operator will not be able to "Force" (Start) a DPF regeneration manually. Also, because the Engine Control Module (ECM) was not programmed for the mistakenly installed optional DPF Regeneration Inhibit Switch to function, the "Inhibit" function is not available.
