Official summary
PUMP, Auxiliary Coolant If a vehicle exhibits a continuous parasitic battery drain traced back to the Aux Coolant pump, prior to replacing part please review the battery replacement/reconnection procedure where it requires the vehicle to be turned on for one minute (Key On Engine Off) then turned off to reset pump operation. Do not replace the Aux pump for this condition without performing this procedure.
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.
