All involved vehicles are identified by VIN in the Global Warranty Management System –
Investigate Vehicle History (GMVIS2) 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.
Additionally, a list of involved vehicles currently in dealer inventory is available on the “Service
Update Bulletin Information” link under the “Service” tab in GM GlobalConnect (US) or attached
to the GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that
return for service, for any reason, and are still covered under the vehicle's base warranty should
also be checked for vehicle eligibility.

PART INFORMATION
No parts are required for this service update.
SERVICE PROCEDURE
Do not attempt to order the calibration number from GM Customer Care and Aftersales. The
calibration numbers required for this service procedure are programmed into control modules
via a Multiple Diagnostic Interface (MDI) or Tech 2 with the calibration update. When using a
MDI or Tech 2 for reprogramming, ensure that it is updated with the latest software version. If
you cannot access the calibration, call the Techline Customer Support Center and it will be
provided.
For step-by-step programming instructions, please refer to SI and the Techline Information
System (TIS) terminal.
1. Verify that there is a battery charge of 12 to 15 volts. The battery must be able to maintain a
charge during programming. Only use an approved Midtronics® PSC 550 Battery Maintainer
(SPS Programming Support Tool EL-49642) or equivalent to maintain proper battery voltage
during programming.
2.

Connect MDI device to the vehicle and access Service Programming System (SPS).

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.
