Only exchange repair units from authorized service centers listed in this bulletin should be used for warranty repairs. The parts listed in the GM parts catalog are new parts for fire and theft repair only, not for warranty repair.

Sections I through VI contain instructions for repair of odometer units (NVM chips, EEPROMS, and odometer assembly). If you are unfamiliar with Cadillac policy regarding alterations of odometer mileage, refer to the Cadillac Service Policies and Procedures Manual, Section I.

Allante combo panel and tape deck procedures are covered in Section VII. Allante radio chassis and radio unit repair will be covered in a separate DSIB.

I. 1985-1988 DeVille and Fleetwood digital instrument cluster.

The digital instrument cluster in 1985-1988 DeVilles and Fleetwoods stores the season odometer mileage in a non-volatile memory (NVM) chip. The cluster and the NVM chip are serviced separately. If cluster replacement is necessary, the NVM chip must be transferred by the dealer from the inoperative cluster to the replacement cluster (refer to Figure 1 for NVM chip location.) Replacement clusters may be obtained through any of the AC Delco service centers listed in Section VIII of this bulletin using the following part numbers.

Digital Cluster Year/Model Application Part Number ---------- ----------- -----------

If the NVM chip requires replacement, the new NVM chip should be installed in the original cluster by the dealer. Replacement NVM chips may be ordered through any of the AC Delco service centers listed in Section VIII. The service center will require correct mileage information in order to program the replacement NVM chip.

For warranty purposes use Labor Operation N4180 at .6 hour for cluster replacement or NVM chip replacement.

II. 1985-1988 De Ville and Fleetwood analog instrument cluster.

1985-1988 DeVilles and Fleetwoods with the analog cluster require the odometer assembly be transferred by the dealer from the inoperative cluster to the replacement cluster. If the odometer is replaced, it should be ordered from GMSPO, using P/N 25054552, and a mileage sticker must be placed on the driver's door. Replacement clusters are available from any of the AC Delco service centers listed in Section VIII using the following part numbers.

V. 1986-1988 Eldorado and Seville, and 1987-1988 Allante BCM EPPROM and EEPROM.

The BCM in 1986-1988 Eldorados, Sevilles, and Allantes use two types of PROM's, an EPROM and and EEPROM. Refer to the appropriate Service Information Manual Section 8D2 to distinguish between EPPROM and EEPROM locations inside the BCM.

The EPROM retains information pertaining to those systems controlled by the BCM (i.e., the ECC system, lighting, and displays). The BCM EPROM is serviceable and interchangeable with PROM's from the same model vehicles. New EPROM's are available from GMSPO.

The EEPROM stores information sepcific to the vehicle. This information includes the VIN, season odometer mileage, and body style. Unlike the EPROM, the EEPROM may not be transferred from one vehicle to another. Transferring EEPROM's between cars will result in incorrect odometer readings and possibly incorrect CCDIC messages.

Replacement EEPROM's may be obtained only by calling one of the following AC Delco service centers:

Replacement EEPROM's should be shipped to the dealer within 24 hours if the service center is called before 2:00 P.M. The following information must be given to the service center when calling to request a replacement EEPROM.

1. VIN

2. Is the vehicle U.S. or Canadian?

3. Is the vehicle a two or four door?

4. Mileage

5. Dealer code and mailing address.

In the event the exact mileage is not known, a replacement EEPROM may be obtained with either zero miles or the most recent known mileage. An EEPROM with zero mileage should only be requested when the vehicle mileage is not accurately known. An odometer replacement sticker with the approximate mileage must be installed on the driver's door when installing an EEPROM with zero miles. In some cases, the mileage may be read from the failed EEPROM by the repair center or Delco Electronics, if necessary.

The replacement EEPROM will be shipped to the dealer with a claim form originated by the service center. This form must be completed by the dealer and returned to the service center with the replaced EEPROM. One copy of the claim form should be retained and attached to the R.O. The remaining forms must be returned to the service center with the replaced EEPROM. Failure to return the replaced EEPROM with the claim form will result in a $200 core charge. Zones will be notified of any EEPROM's not returned within 60 days. (All returned EEPROM's are checked for proper mileage and the results reported to Cadillac.)

For warranty purposes use Labor Operation N4150 at .9 hour for combo panel or tape deck replacement, N2000 at .2 hour for right switch pod replacement, and N2001 at .2 hour for left switch pod replacement.

VIII.AC Delco Service Center Locations.

Exchange units may be obtained by calling one of the authorized AC Delco service centers listed. Exchange units will be shipped from the service center via UPS within 24 hours of the request. Included with the units will be a memo billing in the amount of the core charge, a pre-addressed shipping label, and an ACD-1078 warranty form. The memo billing will be canceled when the inoperative unit is returned to the service center.

The service center will bill dealers directly for all out-of-warranty repairs and cancel the memo billing upon receipt of the failed unit. The ACD-1078 warranty form must be filled in completely by the dealer and all five copies of the form must be returned with the inoperative unit. It is important to describe, as completely as possible, the problem with the inoperative unit and when the problem occurred (i.e. all the time, only after two hours of operation, only on cold mornings, etc.) in the "nature of the problem" area of the form. NOTE: Failure to return the ACD-1078 warranty form of the inoperative instrument cluster to the service center within 30 days of the date of exchange unit was shipped may result in a repair fee or an instrument cluster replacement fee. When the dealer copy of the ACD-1078 form is returned to the dealer, it should be attached to the scrapping copy of the R.O.

Electrtonic instrumentation is fragile. To avoid shipping damage, the inoperative unit must be carefully packed in the reusable shipping container in which the exchange unit was received and returned to the service center immediately.

It is best to carry the exchange unit to the vehicle in the shipping container and carry the inoperative unit out of the vehicle in the shipping container. This will reduce the risk of damage to the exchange unit and guarantee that the inoperative unit is returned in the same container. Failure to return the inoperative unit in the original shipping container will result in a $10.00 replacement cahrge to the dealer.

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.
