Service bulletin 167-T2604-2

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

TT-26-002 Post Campaign AB5R0x or AB5S0x Supplement Manuals. After completing emissions campaign AB5R0x or AB5S0x, future diagnosis might be required. The purpose of this TechTip is to assist with locating supplement service manuals for post emissions campaign trucks that have completed campaign AB5R0x or AB5S0x

The document

• NHTSA's copy of the document (PDF)
• If that address does not open, try this one

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.
