CAMPAIGN: ANALOG INSTRUMENT PLANEL CLUSTER. Cadillac Seville 1996

SUBJECT: ANALOG INSTRUMENT PANEL CLUSTER

MODELS: 1996 Cadillac Eldorados and Sevilles

TO: ALL GENERAL MOTORS DEALERS

General Motors of Canada Limited has determined that CERTAIN 1996 Cadillac Eldorados and Sevilles fail to conform to Canada Motor Vehicle Safety Standards (CMVSS) 101 "Control Location and Identification," 108 "Lighting Equipment" and 208 "Seat Belt Installation." The analog instrument panel cluster on some of these vehicles may experience an internal short circuit. This short circuit can disrupt the pass key system and cause a no-start condition.

Also, if the short circuit occurs while driving, the instrument cluster will go blank, causing loss of gauge function and all Tell-Tale indicators except for ABS, SIR, Park Brake and Service Engine Soon. The loss of the Tell-Tales for seat belts, tum signals, high beam, hazard, oil pressure, coolant temperature and others results in noncompliance with certain safety standards.

To prevent the possibility of this condition from occurring, and in order to comply with CMVSS 101, 108 and 208, dealers are to inspect and, if necessary, replace the instrument panel cluster.

VEHICLES INVOLVED:

Involved are CERTAIN 1996 Cadillac Eldorados and Sevilles equipped with sport interior/analog instrument cluster (Option Code UY9) and built within the following VIN breakpoints:

17. Theft Relearn Procedure

The IPC controls the Pass Key System by reading the ignition key resistor pellet value stored in the IPC EEPROM. The result of this comparison determines whether the IPC will allow vehicle starting by sending vehicle password message to the PCM which then enables the starter relay and injectors.

After replacing the IPC, the PGM must be put into password learn mode to be reprogrammed to the new IPC password. To put PCM into password learn mode, turn the ignition on for 11 minutes, then turn it off for at least 30 seconds. Repeat this sequence three times (i.e.: total of 34.5 minutes). Note that battery voltage must be within normal limits (11-16 volts) during this procedure.

18. Install Campaign Identification Label.

INSTALLATION OF CAMPAIGN IDENTIFICATION LABEL

Clean surface of radiator upper mounting panel and apply a Campaign Identification Label. Make sure the correct campaign number is inserted on the label. This will indicate that the campaign has been completed.

Dear General Motors Customer:

Also, if the short circuit occurs while driving, the instrument cluster will go blank, causing loss of gauge function and all Tell-Tale indicators except for ABS, SIR, Park Brake and Service Engine Soon. The loss of the Tell-Tales for seat belts, turn signals, high beam, hazard, oil pressure, coolant temperature and others results in noncompliance with certain safety standards.

To prevent the possibility of this condition from occurring, and in order to comply with CMVSS 101, 108 and 208, your dealer will inspect and, if necessary, replace the instrument panel cluster.

This service will be provided for you at no charge.

Please contact your GM dealer as soon as possible to arrange a service date.

If parts are required, ask your dealer for details regarding their availability. If parts are not in stock, they can be ordered before scheduling your service date.

This letter identifies your vehicle. Presentation of this letter to your dealer will assist their Service personnel in completing the necessary correction to your vehicle in the shortest possible time.

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

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.
