All Rights Reserved. Page 2 August 2013 Bulletin No.: 12312A 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, or sent directly to export dealers. 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 for this program. SERVICE PROCEDURE Engine Control Module Programming 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) and TIS2WEB 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 August 2, 2013 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. Capture and record Engine Oil Life information. Write down remaining oil life as a percentage. 2. 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. Note: If a programming failure occurs, refer to Engine Control Module Recovery Steps in this bulletin. 3. Reprogram the engine control module (ECM). Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required. 3.1 Connect the MDI to the vehicle. If using MDI, connect to programming terminal with the cable (USB or LAN). 3.2 Select J2534 MDI and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen. 3.3 Select ECM Engine Control Module—Programming from the Supported Controllers screen. 3.4 Follow the on-screen instructions. 4.

Engine Control Module Recovery Steps 1. Disconnect the programming device. 2. Power down the control modules connected to the GMLAN bus by disconnecting the positive battery cable for 2 minutes. 3. Reconnect the positive battery cable. 4. Using MDI, connect to the programming station or Notebook using a cable (LAN). 5. Reboot the programming station or Notebook. This is to make sure nothing is in memory. Note: Selecting Replace and Reprogram from the Select Diagnostic Tool and Process Screen is REQUIRED because some of the calibrations may be erased from the initial attempt to reprogram the module. 6. Reprogram the engine control module. Select Replace and Reprogram from the Select Diagnostic Tool and Process Screen. 7. Follow the on-screen instructions to complete the programming event. 8. Clear all DTCs. Note: Repeat Steps 1-8 above IF another programming failure occurs.

COURTESY TRANSPORTATION – For US and Canada 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. WARRANTY TRANSACTION INFORMATION Submit a transaction using the table below.

Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle, or ownership, through August 31, 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.

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. We Support Voluntary Technician Certification Page 5 August 2013 Bulletin No.: 12312A Dear General Motors Customer: This letter is sent to inform you that General Motors is conducting a customer satisfaction program that affects your 2010-2011 model year Buick LaCrosse, 2011-2012 model year Buick Regal, or 2010-2012 model year Chevrolet Equinox or GMC Terrain, equipped with a 2.4L engine. GM recently introduced into production a software update for the oil life monitor system. This new software will enhance the way the engine oil is monitored. In most cases, this update will recommend more frequent oil changes to support engine durability and overall operating costs. At no-charge, your GM dealer will update your vehicle with these same improvements. What We Will Do: Your GM dealer will reprogram the engine control module. This service will be performed for you at no charge until August 31, 2015. What You Should Do: To limit any possible inconvenience, we recommend that you contact your dealer as soon as possible to schedule an appointment for this update. As a reminder, to ensure proper engine performance and long life, careful attention must be paid to the engine oil. A lack of proper engine oil maintenance can damage the engine. Following these simple, but important steps, will help protect your engine. Always use the engine oil approved to the proper specification and of the proper viscosity grade that is in your Owner Manual. Check the engine oil level regularly and maintain the proper oil level. It is a good idea to check the engine oil level at each fuel fill. Change the engine oil at the appropriate time. If you have any questions or concerns that your dealer is unable to resolve, please contact the appropriate Customer Assistance Center at the number listed below.
