Service Update: Certain vehicles may have an Engine Control Module that does not properly respond to certain service tool requests for the datafile CALID (part number) and CVN (checksum). This condition may cause a vehicle to fail an emissions Inspection/Maintenance (I/M) test. Dealers are to reprogram the Engine Control Module.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
