PRODUCT EMISSION CAMPAIGN 99085 - CRANKSHAFT POSITION SENSOR FAILURES

Model(s): 2000 Cadillac Eldorado And Seville

Section: Product Campaigns

Bulletin No.: 99085

Date: December 1999

SERVICE INFORMATION

General Motors has decided to conduct a Voluntary Emission Campaign involving certain 2000 Cadillac Eldorado and Seville model vehicles equipped with 4.6L (RPO LD8 - VIN Code Y, or RPO L37 - VIN Code 9) engine. The crankshaft position sensors in these vehicles may fail and cause an intermittent engine chuggle, stall or possible long starting crank time and/or a no start condition, as well as illumination of the Malfunction Indicator Lamp (MIL). These conditions may be caused by a cracked solder joint at a resistor in the sensors.

To correct this condition, dealers are to replace both crankshaft position sensors.

VEHICLES INVOLVED

Involved are certain 2000 Cadillac Eldorado and Seville model vehicles equipped with 4.6L engine (RPO LD8 - VIN Code Y, or RPO L37 - VIN Code 9) and built within the following VIN breakpoints:

VEHICLES INVOLVED

Year	Division	Model	Plant	From	Through
2000	Cadillac	Eldorado	Hamtramck	YU101752	YU177716
2000	Cadillac	Seville	Hamtramck	YU102055	YU190443

NOTE: Dealers should confirm vehicle eligibility through VISS (Vehicle Information Service System) 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 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.

PARTS INFORMATION

Parts required to complete this campaign are to be obtained from General Motors Service Parts Operations (GMSPO). Please refer to your "involved vehicles listing" prior to ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency, parts should be ordered as CSO = Customer Special Order.

CUSTOMER NOTIFICATION

Customers will be notified of this campaign on their vehicles by General Motors (see copy of typical customer letter included with this bulletin - actual divisional letter may vary slightly).

In order to ensure full protection under the emission warranty, and the right to participate in future recalls, the customer notification letter recommends that customers have their vehicles serviced as soon as possible. It also advises that failure to do so could legally be determined to be lack of proper maintenance. The vehicle may fail a state or local emission inspection test if the recall work is not completed.

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.

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 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.

When a California emissions campaign is completed by a GM dealer, the dealer must provide the vehicle owner a "Proof Of Correction Certificate" which the owner may need to present to the California Department Of Motor Vehicles (DMV) when renewing their vehicle registration. Without this correction certificate, the owner may be unable to renew their vehicle registration.

Additional Certificates can be obtained, at no charge, from Dealer Support Materials by calling 1-888-414-6322 (Monday-Friday, 8:00 a.m. to 5:00 p.m. EST). Ask for GM Item Number 1825 when ordering.

Dear Cadillac Customer:

This notice is sent to inform you that General Motors is conducting a voluntary emission recall campaign that includes your vehicle.

Reason For This Recall: General Motors has decided to conduct a Voluntary Emission Campaign involving certain 2000 Cadillac Eldorado and Seville model vehicles equipped with 4.6L engine. The crankshaft position sensors in these vehicles may fail and cause an intermittent engine chuggle, stall or possible long starting crank time and/or a no start condition, as well as illumination of the Malfunction Indicator Lamp (MIL). These conditions may be caused by a cracked solder joint at a resistor in the sensors.

What Will Be Done: To correct this condition, your dealer will replace the crankshaft position sensors. This service will be performed for you at no charge.

Contacting Your Dealer: Please contact your Cadillac dealer as soon as possible to arrange a service date and to assure parts availability. Instructions for making this correction have been sent to your dealer. Please ask your dealer if you wish to know how much time will be needed to schedule, process and repair your vehicle. Your Cadillac dealer is best equipped to obtain parts and provide services to correct your vehicle as promptly as possible.

Should your dealer be unable to schedule a service date within a reasonable time, you should contact the Cadillac Customer Assistance Center at 1-800-458-8006. The deaf, hearing impaired, or speech impaired should call 1-800-833-2622 (Utilizes Telecommunication Devices for the Deaf/Text Telephones TDD/TTY).

If you no longer own this vehicle, please let us know by completing the reply card and returning it to us in the postage paid envelope.

Emission Law Information: In order to ensure your full protection under the emission warranty made applicable to your vehicle by State or Federal Law, and your right to participate in future recalls, it is recommended that you have your vehicle serviced 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 if this recall is not accomplished.

IMPORTANT MESSAGE FOR CALIFORNIA RESIDENTS

The California Air Resources Board (CARB) requires vehicle emission recall 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 "Proof Of Correction Certificate". 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 continued satisfaction with our products.
