DEALER ACTION

To prevent the possibility of this condition occurring, dealers are to inspect and, if required, replace the canister purge TVS on all involved vehicles. If there is evidence of intentional disablement of the evaporative emission system, the dealer is to notify the vehicle owner of this condition and ask if he/she wants the system restored. Restoration cost is the responsibility of the owner.

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.

Whenever a vehicle subject to this campaign is taken into your used car inventory, or it is in your dealership for service, you are to ensure the campaign correction has been made before selling or releasing the vehicle.
Dealers are to contact owners of vehicles recently sold from your used vehicle inventory and arrange for the campaign correction to be performed.

DEALER MATERIAL

If your dealership has vehicles involved in this campaign, you will receive the following items:

^ Listing of all vehicles involved in this campaign in the area of your dealership.

^ One (1) campaign identification label for each vehicle.

Involved vehicles have been identified by Vehicle Identification Number Computer listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to the 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.

OWNER NOTIFICATION

Owners will be notified of this campaign by Buick Motor Division (See copy of owner letter included with this bulletin).

CHANGE OF OWNER INFORMATION

Dealers are to use the Dealer Communication System (DCS) to provide Buick Motor Division with subsequent Buick Owner Information. By reporting a change of owner name or address of a vehicle in campaign status over the DCS, the need to send a CVAR form for that vehicle is eliminated. Terminal input instructions are covered in the DCS Manual under Section 9, Page 9-J01A and B.

PARTS INFORMATION

Parts required to complete this campaign are to be obtained from General Motors Service Parts Operations (GMSPO). To ensure that parts are obtained as soon as possible, they should be ordered on a C.I.O. order with NO special instruction, but on an advise code (2).
