Service bulletin 14126B
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
14126B - SERVICE UPDATE (REVISED PROGRAMMING INFORMATION). THIS BULLETIN PROVIDES A SERVICE PROCEDURE TO REPROGRAM THE INSTRUMENT PANEL CLUSTER ON CERTAIN VEHICLES. THESE VEHICLES MAY HAVE AN ODOMETER READING AT “PEEK IN” (I.E.
