A lower cost, high voltage battery pack refurbish kit is now available when the battery
pack assembly needs to be replaced for certain repairs where cell replacement is
needed.
⇒ This refurbish kit includes 6 new match-balanced P2.7 lithium sections.

Information

This refurbish kit can be used in place of a full (New) P2.6 or P2.7 pack. If coolant is
found inside the pack or if the vehicle has P0AA6 set, a refurbish kit cannot be used. The
complete pack must be replaced.
Note: For 2015 the HPCM2 and the BECM will need to be reprogrammed to support the
P2.7 cell chemistry. Dealers will need to contact Techline to have the calibrations ported
over for that VIN.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job
properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
