Service bulletin PIT5804
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
This Preliminary information communicates that a customer may bring a vehicle in with an SES light on. If the technician finds a code P2B87 (auxiliary coolant pump underspeed) set in the ECM they are directed to not replace the G17 heater coolant pump because this will not fix the concern. The techician is instructed to clear the code and release the vehicle to the customer with the explanation that an updated calibration will be released in the future to address the code setting.
