Service Procedure
Important: Before performing any repairs, dealers
should reference previous GM Service Bulletin
17-NA-142 to check phone compatibility and validate
the function of the wireless device charger with special
tool EL 51755-A.
Before any further steps are taken, dealers should
confirm that the vehicle is equipped with K4C or 5ZI,
the GEN I wireless charging system is operating as
intended, and if the customers phone is compatible with
the GEN I wireless charging system.
If equipped with K4C or 5ZI, the system is operating as
intended and the customer’s phone is not compatible,
then the dealer can offer the customer to purchase a
GEN II wireless charging retrofit kit, P/N 84526978. The
suggested list price is $99.00 (USD). Dealers in
Canada should refer to GMCC suggested list price.
The GEN II wireless charging system is compatible with
the latest cell phones, and is intended to wirelessly
charge without a cell phone protective cover. Due to
various sizes and styles of cell phone protective covers,
GM cannot guarantee that a cell phone with a cover
installed will wirelessly charge.
Bulletin No.: 18-NA-153
Upgrading to a GEN II wireless charging system will not
change the dimensions of the charging pocket or pad. If
the customer’s phone does not fit in the GEN I wireless
charging configuration, it will not fit in the GEN II
wireless charging configuration.
Note: This kit is intended as customer pay and will not
be allowed under warranty.

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.
