This service update includes vehicles in dealer inventory and customer vehicles that

vehicle's New Vehicle Limited Warranty period.
PURPOSE
This bulletin provides a service procedure to inspect and, if necessary, replace the battery
current sensor on certain 2013 model year Cadillac Escalade, Escalade ESV; Chevrolet Tahoe,
Suburban; GMC Yukon, Yukon XL; 2013-2014 model year Chevrolet Captiva, Captiva Sport;
and 2014 model year Chevrolet Silverado and Sierra vehicles. An incorrect battery current
sensor may have been installed on the negative battery cable assembly. This could cause an
incorrect reading of the battery state of charge, resulting in under charging of the battery.
This service procedure should be completed as soon as possible on involved vehicles
currently in dealer inventory and customer vehicles that return to the dealer for any type
of service during the New Vehicle Limited Warranty coverage period.
VEHICLES INVOLVED
All involved vehicles are identified by VIN in the Global Warranty Management System –
Investigate Vehicle History Application. Dealership technicians should always check this site to
confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is
important to routinely use this tool to verify eligibility because not all similar vehicles may be
involved regardless of description or option content.

DEALER PROGRAM RESPONSIBILITY
Whenever a vehicle subject to this service update enters your vehicle inventory, or is in your
facility for service in the future, and the vehicle is still covered under the New Vehicle Limited
Warranty, you must take the steps necessary to be sure the service update correction has been
made before selling or releasing the vehicle.

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 tools,
equipment, 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 dealer for information on whether your vehicle may benefit from the information.
