Important: Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or DCS Screen 445 (IPC only) prior to beginning campaign repairs. [Not all vehicles within the above breakpoints may be involved.]

Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number, customer name and address data have been prepared, and are being furnished to involved dealers with the campaign bulletin. The customer name and address data furnished will enable dealers to follow up with customers involved in this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

These dealer listings may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign.

Parts Information

Most of the calibrations for the carlines and years affected by this campaign are included and available from GM Service Operations beginning with the TIS 2000 # 12 CD-ROM release of June 21, 2000.

Important: Do not attempt to order the calibration number from GMSPO. The calibration numbers are programmed into the vehicle PCM via a Techline tool device.

Service Procedure

Important: A Techline CD ROM titled "Disc #12" (June 21, 2000) or later, "Disk #8" (July 25, 2001) or later for CNG, including the current Techline Information System 2000 (TIS 2000) software, will be required to properly program all vehicles. A Tech 2 will be required to reprogram all vehicles involved.

  1. Prep the vehicle for Powertrain Control Module reprogramming.
  2. Program the PCM using TIS 2000 data version #12 for 2000 or later, #8 for 2001 or later for CNG. Refer to up-to-date Techline equipment user instructions.
  3. Install the GM Campaign Identification Label.

Campaign Identification Label

Place a Campaign Identification Label on each vehicle corrected in accordance with the instructions outlined in this Product Campaign Bulletin. Each label provides a space to include the campaign number and the five (5) digit dealer code of the dealer performing the campaign service. This information may be inserted with a typewriter or a ball point pen.

Put the Campaign Identification Label on a clean and dry surface of the radiator core support in an area that will be visible to people servicing the vehicle. When installing the Campaign Identification Label, be sure to pull the tab to allow the adhesion of the clear protective covering. Additional Campaign Identification Labels for US dealers can be obtained from Dealer Support Materials by calling 1-888-549-6152 (Monday-Friday, 8:00 am to 5:00 pm EST). Ask for Item Number S-1015 when ordering.

Additional Campaign Identification Labels for IPC dealers can be obtained from your Regional Marketing Office.

Dealer Campaign Responsibility

All unsold new vehicles in dealers' possession and subject to this campaign MUST be held and inspected/repaired per the service procedure of this campaign bulletin BEFORE customers take possession of these vehicles.

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer 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.
