Information

A lower cost, high voltage battery pack refurbish kit is now available when the battery
pack assembly needs to be replaced.
– This refurbish kit includes 3 refurbished P1.7 lithium sections.
Pack Kit 19418875 can be used in place of a full (New) P1.4, P1.5, or P1.7 pack or when
a section is unavailable.
Note: For 2011-2012 models , the HPCM2 will need to be reprogrammed to support the
P1.7 pack. TAC will contact Techline to have the cals 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.
