Product Enhancement for Inventory and Customer Vehicles - Drivers Seat Module Reprogram-Expires with Base Warranty

THIS PRODUCT ENHANCEMENT INCLUDES VEHICLES IN DEALER INVENTORY AND CUSTOMER VEHICLES THAT RETURN FOR ANY TYPE OF SERVICE, AND WILL EXPIRE AT THE END OF THE INVOLVED VEHICLE'S NEW VEHICLE LIMITED WARRANTY PERIOD.

This bulletin provides a service procedure to reprogram the driver's seat module on certain 2006 Buick Rainier; Chevrolet TrailBlazer and TrailBlazer EXT; GMC Envoy and Envoy XL, and Saab 9 7X vehicles equipped with memory seats (RPO AAB/YC5/YC6) and OnStar® (RPO UE1). On rare occasions, at vehicle start-up, these vehicles may have an extended bulb check and the XM Satellite Radio may take a few seconds longer to activate. The heated seats, door locks, and power windows may also be inoperative until the key is removed from the ignition.

This reprogramming should be completed as soon as possible on involved vehicles currently in dealership/retailer inventory and customer vehicles that return to the dealer/retailer for any type of service during the New Vehicle Limited Warranty coverage period.

A list of involved vehicles currently in dealer/retailer inventory is attached to the Administrative Message (GM US), Dealer Communication (Canada), or IRIS (Saab U.S.), used to release this bulletin. Customer vehicles that return for service, for any reason, and are still covered under the vehicle's base warranty, and are within the VIN breakpoints provided below, should be checked for vehicle eligibility in the appropriate system listed below.

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.

Notice: Before reprogramming, please check the battery condition to prevent a reprogram error of the driver's seat module 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 lamps, 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 Tech 2® 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.

Program the driver's seat module (DSM) to the latest calibration part number. Be sure to use the Pass Thru programming method using both the Tech 2® with CANDi module and the TIS terminal.

Important: Use data version 2.5 or later, broadcast to dealers on February 20, 2006 (US), February 22, 2006 (Canada), and on TIS CD-ROM Version 3.0/2006, mailed to dealers beginning March 15, 2006. To complete this service procedure, the Tech 2® must also be updated to release 26.002 or greater. If you cannot access the calibration, call the Techline Customer Support Center at 1 800 828 6860 (English) or 1 800 503 3222 (French) and it will be provided.
