General Information On AC-Delco Repair/Exchange Programs -------------------------------------------------------- Exchange Parts Availability/Pre-Exchange Units: ---------------------------------------------- AC-Delco Service Centers identified in this DSIB will have a limited supply of exchange parts available. Refer to Table 1. The centers are authorized to do "pre-exchanges", that is sending an exchange unit to the dealership in advance of receiving a problem unit for repair. Prior approval of the owner to accept a repaired or exchange unit must be obtained and noted on the repair order.

Service of the Supplemental Inflatable Restraint DERM and of CDM radio components (1990-1993 Allante remote radio receiver, CD player used in 1990-1991 Eldorados and Sevilles, 1990-1992 DeVilles and Fleetwoods [FWD], l992-1993 Eldorados and Sevilles, and 1993 Fleetwood and Fleetwood Brougham [RWD} remote radio receiver) will be only pre-exchange through one of the centers listed in Table 1. Refer to Section 2, Radio, and Section 4, SIR DERM.

Requesting Exchange Parts:

Before calling a Repair Center to request exchange parts, begin completing an AC-Delco form 1078. The following information will be required at the initial phone call:

1. Cadillac dealer code (when ordering Cadillac exchange parts).

2. Dealer name, shipping address, and phone number.

3. Whether exchange is for a vehicle in or out of warranty.

4. Part number and description of needed part.

5. Repair Order number.

6. Vehicle I.D. number.

7. Delivery Date and Mileage.

8. For BCM EEPROM orders and NVM chip orders, have exact mileage available and have export options available. (U.S./Sweden-Norway/Canada/Leaded Fuel/Japan)

IMPORTANT: Timely return of "core" units is essential to the success of the exchange programs. Unreturned units result in local parts shortages at all dealerships serviced by the Repair Center. Delinquent core returns could result in a debit to the dealership open parts account.

Locating, Exchange Parts (Domestic Only):

To locate exchange stock, first call any of the repair shops listed in Section 1, Table 1. Cadillac would prefer that the dealerships use the shop closest to their location. Dealerships may call any of the shops in Section 1, Table 1 for an exchange part.

o All shops are authorized to ship to any Cadillac dealer.

o All shops are required to deliver units by next day service to dealerships in cases where the shop is not within driving distance. The only exceptions to this rule are non - CDM radios which can be repaired at any radio shop listed in AC-Delco publication WA-2. In the case of non-CDM radios, exchange shops are authorized to ship next day service at dealer request, as needed, to satisfy a Cadillac customer.

As independent businesses, the shops may not refer a dealership to another shop for service when an exchange unit is not available. AC-Delco provides a service to help dealerships locate instrument cluster/display and radio exchange parts. The service will apply to the following Cadillac components:

o All analog and digital clusters

o All radios

o Dealer installed Delco Electronics cellular telephones

In the event that an exchange part is not available from the nearest AC-Delco Service Centerlisted in Cadillac Dealer Service Information Bulletin 92-I-1:

1. Have available the name and number of the AC-Delco shop which you initially contacted for parts. Only the shops listed in Table 1 will have exchange stock available.

2. Call (313) 635-1542 between the hours of 7:30 AM and 4:30 PM Eastern Daylight Time.

3. Advise the operator of the part name and number needed, the AC-Delco shop initially contacted, the dealership name, address, and telephone number.

4. The operator will locate the nearest Service Center with an available pre-exchange unit and the Service Center will advise the dealer when delivery can be expected.

Whenever additional service parts assistance is required, contact your nearest AC-Delco regional office as indicated on page 2 of AC-Delco publication WA-2.

Customer Complaint Information: ------------------------------[B[B Customer complaint information provided to the shops' by dealerships is critical to the shops' ability to correctly repair returned units. Good customer complaint information is as important to a repair shop as it is to a dealer technician. Dealerships can help to assure proper repair of radios, clusters' and SIR DERM's by providing complete and accurate information about the customer complaint and the reason that the part is being returned for repair.

AC-Delco Exchange/Repair Process and Cadillac Warranty Claim Procedure: ---------------------------------------------------------------------- Use the following procedure for those components listed on page 1 which are marked with 1:

1. Remove the unit requiring repair from the vehicle; complete all red shaded areas of the AC-Delco Warranty Repair Claim (ACD-1078A). Send the unit and all five copies of the completed form to the authorized AC-Delco center chosen from Table 1 or from AC-Delco publication WA-2. ALL INFORMATION EXCEPT FOR THE DEALERS SIGNATURE MUST BE PRINTED LEGIBLY OR TYPED.

IMPORTANT: Nature of Problem, Field #3 'is particularly important. To assure accurate diagnosis and repair of the returned unit, also attach a Repair Order copy; and in the case of a radio, the Audio System Condition form. Refer to DSIB 89-I-25. Additional ASC forms (publication H-2650) can be ordered at no cost from Helm, Incorporated; RO. Box 07130; Detroit, MI 48207 using the Service Publications Order form or by calling 1-800-782-4356.

2. The repaired unit will be returned to the dealership with the dealership copy of the AC-Delco form, properly completed. In cases where the dealership has received a pre - exchange unit, the completed form will be mailed after return of the inoperative unit to the Repair Center.

3. A Cadillac warranty claim is to be submitted for the R&R of the unit. An additional .2 hour sublet administrative allowance will be paid if applied for when components are repaired under warranty by an AC-Delco Service Center or another qualified service outlet. This additional time should be entered in the "other labor hours" column of the Cadillac warranty claim.

4. The dealer copy of the ACD - 1078A and the freight receipt or shipping invoice are to be retained in accordance with requirements detailed in the current Cadillac Service Policies and Procedures Manual.

5. If the repair is done by the dealer, or sublet to other than an AC-Delco Service Center, credit will be allowed on a Cadillac Warranty Claim. Allowances for such repairs are included in the Labor Time Guide. Sublet repair charges should be included on the claim and the sublet bill retained in the usual manner.

IMPORTANT: Timely return of "core" units is essential to the success of the exchange programs. Unreturned units result in local parts shortages at all dealerships serviced by the Repair Center. The inoperative product is to be returned to the supplying Service Center in the reusable shipping container which contained the exchange product and a pre-addressed shipping label.

Failure to return the inoperative unit in the SPECIAL REUSABLE CONTAINER may result in a container replacement fee. Failure to return the ACD-1078 within 30 days of the date the exchange unit was shipped may result in a repair fee. Delinquent core returns may result in a debit to the dealership open parts account.

Unusual Radio Interference Conditions/Radio System Sublet Work: -------------------------------------------------------------- It is the responsibility of the dealership to diagnose and repair radio system problems such as interference conditions caused by other components on the vehicle. Complete audio system diagnosis can be found in Section 9A, Audio Systems, in the 1993 Service Information Manuals. The 1993 Section 9A contains E&C data bus diagnosis for Fleetwood Brougham (RWD), Eldorado/Seville, and Allante, diagnosis for switch pops and noises, and diagnosis for features inoperative such as clock, audio, cassette problems, or CD player problems.

In unusual cases where the dealership has been unable to determine the cause of a problem, it may be necessary to sublet the repairs to an AC-Delco Service Center. The dealership should make. the Service Information Sections 9A and 8A- 1501151 available to the Repair Center for sublet diagnosis.

The Audio System Condition (ASC) form should be filled out to assist the repair shop in diagnosis of the problem. Information about the ASC form is found in DSIB 89-I-25. Additional ASC forms (publication H-2650) can be ordered at no cost from Helm, Incorporated; RO. Box 07130; Detroit, MI 48207 using the service Publications Order form or by calling 1-800-782-4356.

The dealership will be responsible for the cost of repairs made by the AC -Delco Service Center. Prior authorization should be obtained for such repairs before the sublet repair costs are submitted on a warranty claim.

Cadillac recommends use of the shops listed in Table 1 for all repairs of radios and any radio sublet work. The shops listed are stocked with limited numbers of all 1993 Cadillac radio part numbers and have processes in place to repair or exchange all 1993 Cadillac radios.

Dealer Installed Radios:

Delco radios that are dealer installed or dealer upgraded at a later date are covered under either the 12 month/12,000 mile parts warranty or for the remainder of the vehicle's original New Car Limited Warranty Basic Coverage, whichever is greater.

Warranty Claim Submission:

For radios, submit a warranty claim in the normal manner without a parts amount as the part is provided to the dealership by the exchange center. Include the following information:

3. After receiving the replacement part, return inoperative part with a completed return authorization form in the original shipping box via UPS. IMPORTANT: Care should be exercised when packaging the component to prevent damage in transit. To complete the return authorization form, fill out the form, sign the form, attach the pink copy to the R.O., and return the remaining copies with the inoperative unit.

The combo panel tape deck and CD unit are serviceable separately. The tape deck and CD unit must be removed from the combo panel as described in the Service-Information Manual, Section 9A, when either is serviced.

Warranty Claim Submission:

For warranty purposes use Labor Operation N4150 for combo panel, tape deck, or CD unit replacement; N2000 for right switch pod replacement; and N2001 for left switch pod replacement. Refer to applicable Labor Time Guide for times.

On in-warranty repairs a warranty claim can be submitted to Cadillac for labor only listing the applicable Labor Operation. Dealerships may claim a .2 hour administrative allowance as "other labor hours" and may claim shipping charges as "sublet, materials, towing". Parts should not be listed on the claim since a no-charge replacement is being provided by the Repair Center.

IMPORTANT: Timely return of inoperative parts is essential to the success of the exchange programs. Dealers who don't return cores cause part shortages for other dealers.

Failure to return the inoperative part with the claim form will result in the assessment of a core charge by Dayton Speedometer Service of $3,000 for a combo panel, $375 for a tape deck or switch pod, or $650 for a CD unit.

Section 10

Eldorado/Seville/Allante BCM EEPROM (Odometer Chip) (1986-1991 Eldorado/Seville and 1987-1993 Allante) --------------------------------------------------- Overview: -------- The BCM in 1986-1991 Eldorados and Sevilles and 1987-1993 Allantes use two types of PROM'S; an EPROM and an EEPROM. Refer to the appropriate Service Information Manual, Section 8D2, to distinguish between EPROM and EEPROM locations inside the BCM.

The EPROM retains information pertaining to those systems and options 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 specific to the vehicle. This information includes the VIN, season odometer mileage, body style, and some option content information. 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.

Exchange Procedure:

Replacement EEPROM's may be obtained only by calling one of the following AC-Delco Service Centers:

Service Center Service Center Location Name -------------- -------------- California Auto Electronic Radio Illinois D & B Auto Radio, Inc. Florida Techni - Car Pennsylvania H & R Radio

Refer to Table 1 for Service Center phone numbers and addresses.

Replacement EEPROM's should be shipped to the dealer within 24 hours if the Service Center is called before 2:00 PM. 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., Canada, Sweden-Norway, Japan, or Leaded Fuel export?

3. Is the vehicle a two or four door?

4. Exact mileage

5. Dealer code, name, mailing address, and phone number

SEE PAGE 2 OF THIS BULLETIN FOR OTHER INFORMATION REQUIRED FORAC-DELCO EXCHANGES.

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 an ACD - 1078A 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.

o Failure to return the replaced EEPROM with the claim form will result in a $200 core charge.

o Zones will be notified of any EEPROM's not returned within 60 days.

o All returned EEPROM's are checked for proper mileage and the results reported to Cadillac.

Warranty Claim Submission:

For warranty purposes use Labor Operation N4801, EEPROM or EPROM replacement at published time for applicable model year. For EEPROM, a warranty claim should be submitted to Cadillac for labor only. Dealerships may claim a .2 hour administrative allowance as "other labor hours" for EEPROM exchanges and may claim shipping charges for return of the inoperative EEPROM as "sublet, materials, towing".

IMPORTANT: If you are unfamiliar with Cadillac policy regarding integrity of odometer mileage, refer to the Cadillac Service Policies and Procedures Manual, Section 1.

Section 11

Cimarron Digital (1985-1988) and Allante Digital and Analog Cluster

IMPORTANT: DSIB 88-I-26 provides a procedure for dealerships to retrofit analog clusters into 1988 and 1989 Allantes originally equipped with digital clusters (and vice versa). The retrofit procedure will work on 1990-1993 Allantes but will not be covered under warranty.

On 1987-1989 Allantes digital clusters were a no-cost option. The 1990-1993 cars have digital cluster as a customer-pay option on the soft top model (6VS) and as a standard feature on the hard top (6VR). The 1990-1992 hard top model can be retrofit with an analog cluster by the dealership almost at cost due to the difference in core charge for the digital and part cost for the analog. (The digital core payment from VDO-Yazaki will, in most cases, pay for labor and the analog part.) If a customer wants a digital cluster installed into a soft top model, the cost may not be charged to warranty.

Cluster Exchange Procedure:

Replacement instrument clusters may be obtained from VDO - Yazaki using the following procedure:

1. Call the VDO-Yazaki Service Center at (703) 665-2446, -2447, or -2448 and order the appropriate part number listed below: Shipping Core + Repair Total Year/Model Component P/N Charge Charge COD* ---------- --------- --- ------ -------- ----- 1985-1986 J Digital Instrument Cluster 25081527 $165 $192.25 $357.25 1987-1988 J Digital Instrument Cluster 25083444 $150 $177.25 $327.25 1987 V Digital Instrument Cluster 1639259 $320 $350.75 $670.75 1988-1989 V Digital Instrument Cluster 1645296 $320 $350.75 $670.75 1988-1989 V Analog Instrument Cluster 1640823 $135 $162.25 $297.25 1990-1992 V Digital Instrument Cluster 1645299 $320 $350.75 $670.75 1990-1992 V Analog Instrument Cluster 1645300 $135 $162.25 $297.25 1993 V Analog IPC Domestic 3523531 $135 $162.25 $297.25 1993 V Digital IPC Domestic/Canada 3523532 $320 $350.75 $670.75 1993 V Analog Export 3523533 $135 $162.75 $297.25 1993 V Analog U.K. 3523534 $135 $162.75 $297.25

* Core charge will be refunded to dealer via check on receipt of the core at VDO-Yazaki.

2. VDO-Yazaki will request the following information:

A. Dealer code.

B. Dealer's shipping address.

C. Vehicle Identification Number.

D. Owner complaint or observed condition.

E. Diagnosis used to determine the cluster required replacement. VDO-Yazaki is staffed by trained technicians who will attempt to confirm the problem is cluster related and not car system related. The technician or shop foreman should be on hand when calling to answer their questions regarding the diagnosis.

F. If the problem involves the odometer, a mileage figure will be required. The replacement cluster will be shipped with mileage preset.

G. Purchase order number or account number.

H. Whether the repair is covered under warranty or not.

IMPORTANT: Since June of 1989 all clusters have been shipped from VDO-Yazaki to GM dealers via COD. The Repair Center will provide dealerships with a fixed COD amount (see above) to help the dealership to prepare for the cluster COD arrival. After ordering the cluster lease prepare for the COD arrival of the cluster via UPS next - day service. Make cash or a check ready for the dealer representative who accepts UPS parts deliveries in the amount under "total COD".

3. Cimarron Odometer- For digital instrument cluster problems that do not affect the odometer, the mileage memory chip must be transferred from the inoperative cluster to the replacement cluster by the dealer. Refer to Figure 10-1 for NVM chip location. If the problem involves the odometer, the inoperative cluster must contain the mileage memory chip when it is returned.

Allante Odometer- The Allante digital cluster does not contain a mileage memory chip. The mileage is stored in the BCM EEPROM. Refer to Section 9 for EEPROM service. The Allante analog cluster contains an electromechanical odometer which is serviced with the cluster assembly. Replacement analog clusters will come with an odometer pre-set by VDO-Yazaki with the proper mileage.

4. VDO-Yazaki will ship replacement clusters C.O.D. The C.O.D. price will be the "repair charge" and "core charge" listed plus freight.

5. Included with the replacement cluster will be a computer-printed from. To obtain the core refund, this form must be filled out completely and returned with the inoperative cluster to VDO-Yazaki in the shipping container to: VDO-Yazaki 980 Brooke Road Winchester, VA 22601 ATTN: Instrument Cluster Service

1993 Fleetwood/Brougham (RWD) Central Control Module (CCM) ---------------------------------------------------------- Program Overview: ---------------- The 1993 Fleetwood (RWD) and Fleetwood Brougham Central Control Module (CCM) is available on a pre-exchange basis from any of the exchange centers listed in Table 1. Follow the procedure described in Section 1.

Part Information:

The CCM controls the following subsystems on the 1993 Fleetwood/Brougham:

o Retained Accessory Power (RAP)

o Variable Effort Steering (VES)

o Delayed Interior Lighting (DIL)

o PASSKey II

o Exterior Lighting

IMPORTANT: Since the CCM module performs the PASSKey II functions once an exchange module is installed in a vehicle and the ignition is turned to "ON", that module may not be used in another vehicle. It will only start a vehicle having that same PASSKEY value. CCM's must be returned to an exchange center for reprogramming once a PASSKey value is programmed.

Order parts from group 2.560 for fire and theft needs only.

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.
