CONDITION
Certain 2012 model year Cadillac SRX vehicles (produced from July 10, 2012); and 2013 model
year Buick Verano; Cadillac ATS, XTS; Chevrolet Cruze, Equinox, Volt; and GMC Terrain
vehicles, and certain 2012 Buick Verano and Chevrolet Cruze; 2012-2013 model year Cadillac
SRX; Chevrolet Equinox, Volt; GMC Terrain vehicles that were serviced with an incorrect
calibration, may have a condition in which the Automatic Crash Response system may not work
as intended because of a software problem. The Automatic Crash Response system is
intended to enable these vehicles to notify OnStar® if they are involved in certain types of
crashes. The software problem we found affects the vehicle’s ability to notify OnStar ® in
crashes that meet the severity parameters for automatic crash notification but do not trigger
airbag deployment, such as certain rear end crashes. In crashes with an airbag deployment,
the Automatic Crash Response system works as designed.

This condition does not affect the deployment of the airbags or the safety belt pretensioners,
which reduce slack in the safety belt immediately after impact. The airbags and safety belt
pretensioners will deploy as designed. A vehicle occupant will be able to contact an OnStar ®
Emergency Advisor by pushing the OnStar® emergency button.
CORRECTION
Dealers are to reprogram the Sensing and Diagnostic Module (SDM).
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle
History screen in the GM Global Warranty Management system. Dealership service personnel
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 application to verify eligibility
because not all similar vehicles may be involved regardless of description or option content.
For dealers with involved vehicles, a listing with involved vehicles containing the complete
vehicle identification number, customer name, and address information has been prepared and
will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports.
Dealers will not have a report available if they have no involved vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle
Registration Records. The use of such motor vehicle registration data for any purpose other
than follow-up necessary to complete this program is a violation of law in several
states/provinces/countries. Accordingly, you are urged to limit the use of this report to the
follow-up necessary to complete this program.
PART INFORMATION
No parts are required.
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) with the calibration update. When using a MDI for
reprogramming, ensure that it is updated with the latest software version. Use TIS2WEB on or
after 09/13/12 to obtain the calibration. 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.

Reprogram and setup the inflatable restraint and sensing diagnostic module (SDM). Refer
to SI and Service Programming System (SPS) documentation for programming instructions,
if required.
2.1 Connect the MDI to the vehicle.
2.2 Select J2534 MDI and Reprogram ECU from the Select Diagnostic Tool and
Programming Process screen.

Note: After programming the SDM, a SDM setup is required. Refer to Inflatable Restraint
Sensing and Diagnostic Module Programming and Setup in SI.
2.3 Select SDM Inflatable Restraint Sensing and Diagnostic Module -- Programming from
the Supported Controllers screen
2.4 Follow the on-screen instructions.
Note: If a reprogramming error pop up screen is displayed while programming the SDM or the
reprogramming event was interrupted and programming will not complete after trying, refer to
Unable to Program SDM in this bulletin.
2.5 At the Programming Complete screen select "Proceed with same VIN".
2.6 Select SDM Inflatable Restraint Sensing and Diagnostic Module -- Setup from the
Supported Controllers screen.
Note: To perform Setup, cycle the vehicle in and out of RUN mode (Ignition ON). If the vehicle
is not in RUN mode when required, the Setup procedure will not complete. For vehicles with
push button start: To ensure the vehicle is in an ignition ON engine OFF (RUN) mode, press
and hold the start button (foot off the brake) for a minimum of 10 seconds. On the Cadillac SRX,
there will be a full gauge sweep on the IPC and Cadillac crest displayed on the DIC when the
vehicle enters RUN mode.
2.7 Follow the on-screen instructions.
3.

Clear all diagnostic trouble codes (DTCs).

Unable to Program SDM
1. Using the GDS2 scan tool, build the vehicle and proceed to the Identification Information
screen using the following path: Module Diagnostics>Inflatable Restraint Sensing and
Diagnostic Module > Identification Information.
2. Note the value for parameter name “Software Module 1 Identifier.”
 If the value is greater than 0 for this parameter, replace the SDM. Refer to Inflatable
Restraint Sensing and Diagnostic Module Replacement in SI.
Print the
Identification Information screen and retain it with the Repair Order (RO).
 If the value for this parameter is 0, attempt to continue programming one more time
before contacting the Techline Customer Support Center (TCSC) at 1-800-828-6860
(English) or 1-800-503-3222 (French). DO NOT use “Proceed with Same VIN” to
return to return to Supported Controllers screen.
COURTESY TRANSPORTATION
The General Motors Courtesy Transportation program is intended to minimize customer
inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited
Warranties. The availability of courtesy transportation to customers whose vehicles are within
the warranty coverage period and involved in a product program is very important in maintaining
customer satisfaction. Dealers are to ensure that these customers understand that shuttle
service or some other form of courtesy transportation is available and will be provided at no
charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for
Courtesy Transportation guidelines.

CUSTOMER NOTIFICATION – For US and Canada
General Motors will notify customers of this program on their vehicle (see copy of customer
letter included with this bulletin).
DEALER PROGRAM RESPONSIBILITY
All unsold new vehicles in dealers' possession and subject to this program must be held and
inspected/repaired per the service procedure of this program bulletin before customers take
possession of these vehicles.
Dealers are to service all vehicles subject to this program at no charge to customers, regardless
of mileage, age of vehicle, or ownership, through September 30, 2015.
Customers who have recently purchased vehicles sold from your vehicle inventory, and for
which there is no customer information indicated on the involved vehicle listing, are to be
contacted by the dealer. Arrangements are to be made to make the required correction
according to the instructions contained in this bulletin. A copy of the customer letter is provided
in this bulletin for your use in contacting customers. Program follow-up cards should not be
used for this purpose, since the customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this program enters your vehicle inventory, or is in
your facility for service through September 30, 2015, you must take the steps necessary to be
sure the program 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.
