Service bulletin 22504

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

Under certain conditions, the Engine Control Module (ECM) programming may not detect when the Exhaust Gas Recirculation (EGR) flow exceeds the predetermined threshold resulting in not setting a fault code and activating the Malfunction Indicator Light (MIL). Only models equipped with International A26 engine.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
