Customers will be notified of this campaign on their vehicle by General Motors (see copy of divisional customer letter included with this bulletin).


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.

Dealers are to service all vehicles subject to this campaign at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.

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. This could be done by mailing to such customers a copy of the appropriate divisional customer letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this campaign enters your vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.


IMPORTANT: A 1996 Techline CD ROM titled Disc 11 (May 31, 1996) or later software will be required to properly program all vehicles. Refer to Service Information Bulletin 53-65-08 filed in Section 6E for information on programming and the Techline Customer Support Center help line. As indicated in that bulletin, a Tech 2 will be required to program the 1997 LeSabres.

1. Prep vehicle for Powertrain Control Module reprogramming.

2. Flash PCM EE PROM using the #11 CD ROM or later software matching the vehicle. Refer to up-to-date Techline equipment users instructions.

3. Install GM Campaign Identification Label.


Each vehicle corrected in accordance with the instructions outlined in this Product Campaign Bulletin will require a "Campaign Identification Label". 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.

Each "Campaign Identification Label" is to be located on the radiator core support in an area which will be visible when the vehicle is brought in by the customer for periodic servicing. When installing the new Campaign Identification Label, be sure to install the clear protective covering. Additional Campaign Identification Labels can be obtained from VISPAC Incorporated by calling 1-800-269-5100 (Monday-Friday, 8:00 a.m. to 4:30 p.m. EST). Ask for Item Number *-1015 when ordering.

Apply the "Campaign Identification Label" only on a clean, dry surface.


Submit a Product Campaign Claim with the information indicated below:

REPAIR PART FAILED PARTS LABOR LABOR PERFORMED COUNT PART NO. ALLO CC-FC 0P HOURS --------- ----- -------- ----- ----- ----- -----

PROM- 0 N/A N/A MA-96 V9943 0.4 Reprogramming Flash E PROM

Refer to the General Motors Corporation Claims Processing Manual for details on Product Campaign Claim Submission


Dear Pontiac Bonneville Customer:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.


General Motors has decided that a defect which relates to motor vehicle safety exists in the vehicle engine control system of certain 1996 Pontiac Bonneville model vehicles equipped with a 3.8L V6 engine (RPO L36). These vehicles may exhibit, under a certain set of complex conditions, a backfire during engine starting that can cause breakage of the upper intake manifold. This can cause a no-start condition and possibly an engine compartment fire. Also, if a person was in the immediate vicinity of the intake manifold when the hood was open, and this backfire occurred, it could result in personal injury.


To prevent this condition from occurring, your dealer will update the vehicle Powertrain Control Module with new programming software. This service will be performed at no cost to you.


Although the likelihood of this condition occurring is very low, we suggest that the vehicle hood be shut whenever starting your vehicle. If possible, start your vehicle only in an open area.

Please contact your Pontiac dealer as soon as possible to arrange an appointment.

Instructions for making this correction have been sent to your dealer. The labor time necessary to perform this service correction is approximately thirty (30) minutes. Please ask your dealer if you wish to know how much additional time will be needed to schedule and process your vehicle.

Your Pontiac dealer is best equipped to obtain parts and provide service to ensure that your vehicle is corrected as promptly as possible. If, however, you take your vehicle to your dealer on the agreed service date, and they do not remedy this condition on that date, or within five (5) days, we recommend you contact the Pontiac Customer Assistance Center by calling: 1-800-762-2737.

After contacting your dealer and the Pontiac Customer Assistance Center, if you are still not satisfied that we have done our best to remedy this condition, without charge and within a reasonable time, you may wish to write the Administrator, National Highway Traffic Safety Administration, 400 Seventh Street, *. W., Washington, DC 20590 or call 1-800-424-9393 (Washington, DC residents use 202-366-0123).

The enclosed Campaign Customer Reply Card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary inspection/correction in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage-paid Customer Reply Card and returning it to us.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your safety and continued satisfaction with our products.

PONTIAC DIVISION General Motors Corporation

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those 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 equipment, tools, 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 a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
