Customer Satisfaction - Transmission Software and Calibration Update

Certain 2007-08 model year GMC Acadia; Saturn Outlook; and 2008 model year Buick Enclave; Saturn Aura model vehicles were incorrectly reprogrammed by dealers/retailers in normal service and under Customer Satisfaction Program 07217A and Service Update 07235A. The TCM (Transmission Control Module) and ECM (Engine Control Module) both must be reprogrammed with the updated software for correct odometer operation. GM TIS2Web Service Programming System records indicate some vehicles have had only one of the modules reprogrammed, causing incorrect odometer function if the vehicle is driven. Attached to the Administrative Message (US) / Dealer Communication (Canada), used to release this bulletin, is a list, in BAC (US) / Dealer Code (Canada) sequence, of those vehicles which only had one module reprogrammed and which our records indicate are still in your inventory.

Dealers/Retailers are to reprogram the stock vehicles listed using the Programming Sequence procedure to assure that both the ECM and TCM have the updated software. Vehicles which have accumulated mileage with only one of the modules updated must be programmed using the Programming Sequence and must also have the vehicle odometer reading corrected using the service procedure detailed in this bulletin.

Involved are certain 2007-08 model year GMC Acadia; Saturn Outlook; and 2008 model year Buick Enclave; Saturn Aura model vehicles built within these VIN breakpoints:

Important: Dealers/retailers are to confirm vehicle eligibility prior to beginning repairs by using the system(s) below. Not all vehicles within the above breakpoints may be involved.

For dealers/retailers 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 through the applicable system listed below. Dealers/retailers will not have a report available if they have no involved vehicles currently assigned.

-- US GM - GM DealerWorld Recall Information

-- Canadian GM/Saturn dealers/retailers - GMinfoNet Recall Reports

-- US Saturn retailers - Facility VIN List (included with bulletin in GM DealerWorld)

-- Export dealers - sent directly to dealers

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.

Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2® scan tool and TIS 2 WEB website with the following calibration updates:

If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.

If the vehicle has not been driven off the dealer lot since the original reprogram, it only requires the Programming Sequence procedure be performed, according to Bulletins 07217A or 07235A, to reprogram both TCM and ECM to assure correct odometer function. Customer vehicles and dealer stock vehicles, except Saturn Aura, which have accumulated mileage with only one module updated, must have the Programming Sequence performed and the odometer reading corrected. The attached Odometer Worksheet should be copied locally. The worksheet must be completed and the Techline Customer Support Center (TCSC) contacted for further instructions. A VCI will be provided to electronically correct the odometer reading using the Tech 2®. The Saturn Aura odometer reading can not be corrected using this procedure. If a Saturn Aura in the attached retailer stock list has been delivered, or accumulated mileage prior to completion of the Programming Sequence, the VIN must be reported to TCSC for further handling.

Important: When programming vehicles with the software update released in bulletins 07217A and 07235A, and for normal service, it is important that the engine and transmission modules both be updated. If both modules are not updated, odometer function will be affected. The Programming Sequence assures that both modules are updated.

Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during reprogramming. If the vehicle battery is not fully charged, use jumper cables from an additional battery. Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed.

The ignition switch must be in the proper position. The Service Programming System (SPS) application prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so.

Make certain all tool connections are secure, including the following components and circuits:

DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.

DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date.

1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary. Only use approved Midtronics charger or Jumper Packs, etc. to maintain proper battery voltage during programming.
2. Reprogram the Engine Control Module (ECM) AND the Transmission Control Module (TCM).

Important: To ensure both controllers are programmed at the same time select Programming Sequence ECM/TCM on the Supported Controller Screen (Note: This is the last selection in the scroll down box).

3. Vehicle Option select with RPO MH6 without RPO VPM.
4. DTCs may set during programming. Use the clear code function on the program complete screen to clear DTCs.

2007-08 Odometer Correction for Acadia, Outlook; and 2008 Enclave

Important: The "Programming Sequence ECM/TCM" procedure must be performed using the "Pass-Thru" method. You must first select one the following methods in TIS2WEB: J2534 Pass-Thru or Tech 2® Legacy Pass-Thru Programming. DO NOT SELECT " Tech 2® Remote". This procedure can not be used on the Saturn Aura. Contact TCSC with the VIN of a Saturn Aura requiring odometer correction for further handling.

1. J2534 Pass-Thru is the preferred method for the Programming Sequence ECM/TCM. Ensure both the ECM and TCM have been programmed with the latest software and calibration files.
2. Complete odometer worksheet and have it ready when calling the Customer Support Center (TCSC). Refer to the work sheet in this bulletin.
