General Motors has determined that certain 1995 Pontiac Bonneville model vehicles equipped with a 3800 Series II engine (L36) may have a deceleration stall under limited conditions. This could result in a loss of power steering assist, generator and power braking assist.
To prevent this condition from occurring, dealers are to replace the suspect MEM-CAL of the Powertrain Control Module (PCM) with a MEM-CAL of an improved design.
Involved are certain 1995 Pontiac Bonneville model vehicles equipped with a 3800 Series II engine (RPO L36, VIN K) within the following VIN breakpoints:
UP TO AND YEAR MODEL PLANT BEGINNING INCLUDING -------------------------------------------------------------- 1995 Bonneville Orion S4200007 S4213735
Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle Identification Number, owner name and address, and are furnished to involved dealers with the campaign bulletin. Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.
These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.
A preshipment of parts will be sent to involved dealers the week of December 19, 1994. Preshipment will equal parts for 30% of the number of vehicles to be repaired. Preshipment parts will be charged to the dealers' open parts account.
Additional parts required to complete this campaign are to be ordered from General Motors Service Parts Operations (GMSPO). To ensure these parts are obtained as soon as possible, they should be ordered from GMSPO on a "C.I.O." order with no special instruction code, but on an advise code (2).

Owners will be notified of this campaign on their vehicle by Pontiac Division (see copy of owner 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 owners take possession of these vehicles.
Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership, from this time forward.
Owners of vehicles recently sold from your new vehicle inventory with no owner information indicated on the dealer listing, are to be contacted by the dealer, and arrangements made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such owners a copy of the owner letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the owner may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it 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.

Dear Pontiac Owner:
This notice is sent to inform you that Pontiac Division is conducting a Customer Satisfaction recall campaign involving an emission component, that includes your vehicle.
General Motors has determined that certain 1995 Pontiac Bonneville model vehicles equipped with a 3800 Series II engine may have a deceleration stall under certain specific conditions. This could result in loss of power steering assist, generator and power braking assist.
To prevent the possibility of this condition occurring, a component inside the Powertrain Control Module on your vehicle will be replaced with an improved design.
This service will be performed for you at no charge.
Please contact your Pontiac dealer as soon as possible to arrange a service date.
Instructions for providing this service have been sent to your Pontiac Dealer and parts are available. Please ask your dealer if you wish to know how much time your dealer will need to schedule and process your vehicle.
The enclosed Campaign Owner Reply Card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage-paid Owner Reply Card and returning it to us. Should your dealer not schedule a service date within a reasonable time, you should contact the Pontiac Customer Assistance Center by calling 1-800-762-2737. The customer Assistance Center will assist you and the dealer in getting your vehicle serviced.
To ensure your full protection under the emission warranty made applicable to your vehicle by Federal Law, and your right to participate in future recalls, it is recommended that you complete its service as soon as possible. Failure to do so could legally be determined to be lack of proper maintenance of your vehicle. Also, your vehicle may fail a state or local emission inspection test if the recall work is not accomplished.
Should your dealer find that your emission system has been intentionally disabled, you will be asked if you wish the system to be restored so that it will function as designed. The cost of such restoration will be your responsibility.
The California Air Resources Board (CARB) requires that vehicle emission campaigns be completed prior to California registration renewal. Uncorrected emission recall campaigns will result in the inability to renew your California vehicle registration.
At the time of emission campaign completion, your California dealer will issue a "Campaign Certificate of Completion." Keep this certificate and, if required, present it to the Department of Motor Vehicles when renewing your California registration as proof of campaign completion.
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.

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.
