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.
Parts Information
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(R) scan tool and TIS 2 WEB website with the following calibration updates:
^
2007 GMC Acadia and Saturn Outlook: Use data version 9.5 for 2007 or later, available on TIS 2 Web 09/16/07; and on TIS DVD version
10.0/2007 or later, mailed to dealers beginning 10/10/07.
^
2008 GMC Acadia; Saturn Outlook, Aura ; and Buick Enclave: Use data version 8.5 for 2007 or later, available on TIS 2 Web 08/19/07; and on TIS
DVD version 9.0/ 2007 or later, mailed to dealers beginning 09/12/07
If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.
Service Procedure
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 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(R). The Saturn
Aura odometer reading can not be corrected using this procedure. If a Saturn Aura in the 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:
^
The RS-232 communication cable port
^
The connection at the data link connector (DLC)
^
The voltage supply 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 Support Controller Screen (
NOTE: This is the last selection in the scroll down box).
