Condition
Some customers may comment that active (lock/unlock) and passive (vehicle starting)
key FOB functions do not work and that the vehicle will not crank.
Technicians may find DTC P0513 may be set in active or history.
Cause
This condition may have presented immediately following a low voltage condition, jump
start, battery charging, battery replacement or battery disconnect and reconnect. This can
present a memory corruption event in the BCM. Loss of key FOB passive and active can
also follow incorrect immobilizer repair attempts.

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.
