Service bulletin PIC5677A

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.

The readiness monitors will not cause performance or emissions issues but will prevent the emissions scanning tools from confirming the module is performing correctly, causing the vehicle to fail state required emissions tests.
