For 1990-2009 cars

# CELLULAR MOBILE TELEPHONES (OPERATION DESCRIBED)

#### MODELS AFFECTED: 1987-1988 Eldorado, Seville, Allante, DeVille, Fleetwood, Sixty Special, and 1987 Fleetwood 75 Limousine.

This bulletin will explain option content, new car pre-delivery procedures, service procedures and items unique to the cellular mobile telephone system.

#### SYSTEM ORDERED ON NEW CARS (option UV9)

Eldorado, Seville, or Allante

When an Eldorado, Seville or Allante' is ordered with a mobile telephone (option code UV9) the entire telephone system will be factory installed. (The handset, transceiver, mute module, microphone, armrest, owner's manual, tri-band antenna, and all wiring will arrive installed in the vehicle.)

DeVille, Fleetwood, or Sixty Special

When a DeVille, Fleetwood, or Sixty Special is ordered with UV9, everything will be installed with the exception of the antenna, transceiver, handset and user's manual. The antenna assembly will require mounting and will arrive boxed, along with antenna installation instructions, in the luggage compartment of the vehicle. The transceiver, handset and user's manual will be shipped to the dealership in a separate package prior to vehicle delivery. In order to prepare the vehicle for customer delivery, these items need to be installed in the car per the procedures found in the Service Information Manual.

#### ORDERING TELEPHONE PROVISIONS ONLY (option UV8)

If an owner already has a Cadillac cellular mobile telephone system in one vehicle and wishes to share the handset and transceiver with, or transfer them to a second vehicle, it is possible to order a new vehicle with option code UV8, the mobile telephone provisions package. The mobile telephone provisions package includes all the telephone hamesses and cables, the microphone, the antenna, the radio mute module and custom armrest (or armrest insert), but does not include the telephone handset and transceiver.

It must be stressed that only the Cellular Mobile Telephone System available through Cadillac is compatible with the telephone provisions package. Even if other telephone systems' wiring will connect, they will not be fully operational.

Incorporating any portion of the Cadillac telephone system (i.e., harnesses, power tri-band antenna, mute module, etc.) with any non-Cadillac telephone system can result in excessive audio noise, loss of audio to the front speakers, loss of ignition power to the telephone or parasitic battery drain.

#### FACTORY PHONE SYSTEMS FOR STOCK CARS (without UV8 or UV9)

When ordering a cellular telephone system for installation on a stock vehicle, it is necessary to order both a provisions package (includes the wiring, antenna, brackets, installation manual, mute module, microphone, armrest, etc.) and a components package (includes the transceiver, handset, and user's manual). It is possible to order only the components package to complete the phone installation in a vehicle already equipped with the telephone provisions

There are no dealer installed provisions packages available for the 1987 and 1988 DeVille, Fleetwood, Sixty Special or 1987 Fleetwood 75 Limousine. Provisions packages and component packages are available through Cadillac Distribution and should be ordered using the Cadillac Cellular Telephone Provisions Order Form. The packages, ordered from Cadillac Distribution, will be shipped to the dealership by GMSPO. Refer to the applicable Distribution Bulletin for details.

#### PRE-DELIVERY PROCEDURE

Before delivery to the owner, it is necessary to program the telephone to provide service. Programming instructions are included in Section 9E of the Service Information Manual for the Eldorado, Seville and Allante' and in DSIB 86-I-19 for the DeVille, Fleetwood, Sixty Special and Standard Limousine. Programming includes such things as establishing the owner's new cellular telephone number.

#### TELEPHONE NUMBER ACQUISITION

The forms on pages 6 and 7 should be photocopied and used by the dealership to make certain all information necessary to establish customer telephone service has been obtained. (These forms should be kept in the vehicle history file.) Much of the information can be supplied by the customer PRIOR to accepting delivery of the vehicle. It may be beneficial to the customer if the dealership has literature on hand from both local system operators in order to assist owners who are unfamiliar with cellular telephone service in making decisions conceming billing and special feawres.

#### PROGRAMMING THE PHONE

The dealership must use die information received from the System Operator (see page 7) in a simple 10 step programming procedure to program the transceiver Number Assignment Module (NAM). The programming of the telephone system is done with the key pad of the telephone handset. Programming instructions are included with the transceiver, but can also be found in the Service Information Manuals in Section 9E. (See also the NAM Programming Table for 1988 Eldorado, Seville, and Allante' phone systems included in this bulletin on page 8).

#### NOTE: THE PHONE CAN ONLY BE PROGRAMMED 3 TIMES FROM THE HANDSET.

Programming the phone may be practiced as many times as desired so long as the SEND button is not pressed. After 3 times, the phone must be reset by your local Motorola Service Shop (MSS). This involves placing the phone into test mode and invoking the "initialize non-volatile memory to zero" command. The dealership should be advised that this may involve a fee. Once it has been reset by the MSS, it may then be programmed 3 additional times by a dealership until it must be reset again.

#### VEHICLE RECEIVING ISPECTION

Due to the various methods of phone delivery, the following table is provided to help avoid confusion and assure proper inspection of vehicles equipped with the cellular telephone option. Familiarity with each case will also help dealerships identify situations requiring transportation or warranty claims.

An administrative allowance of .2 hours is allowed for either handset (R5113) or transceiver (R5116) replacement, when service by Motorola is necessary.

#### SYSTEM DIAGNOSIS AND REPAIR

Diagnosis and Repair Responsibility

As with any warranted factory equipment, the dealership is responsible for diagnosis and repair of customer complaints regarding phone system operation. Cadillac will reimburse the Dealer for performance of warranty phone system repairs. Motorola Service Shops will provide transceiver and handset diagnosis and repair to the dealership at no charge while under warranty. (See "Transceiver or Handset Service") Some Motorola Shops may volunteer to assist with vehicle phone system diagnosis and repair (operating under applicable Cadillac policy regarding sublet repair) but they are under no obligation to do so. Dealerships will be responsible for providing the MSS with any necessary wiring diagrams and trouble trees. (SIM Sections 9E and 8A-Cell 152)

#### DIAGNOSTIC PROCEDURES AND ASSISTANCE

Following the steps below, a dealership should be able to resolve any cellular telephone problem encountered:

- Consult all appropriate publications.

- This and other Serviceman Bulletins

- Service Information Manual Sections 9E and 8A-Cell 152 for system description, wiring diagrams, and trouble trees

- Cadillac Distribution Bulletins for package ordering information

- As with any factory option, for diagnostic assistance call the Cadillac Technical Assistance Hotline by dialing 1-800-CAD-STAR.

#### Service Parts

All service parts except for the owner's manual will be available from GMSPO. The owner's manual will be made available through:

Helm Incorporated Publications Division P.O. Box 3617 Highland Park, MI 48203

#### Transceiver or Handset Service

When diagnosis indicates handset or transceiver replacement, BOTH components should be provided to the nearest Motorola Service Shop (MSS) which will repair or replace the components at no charge to the dealership while under warranty. The entire vehicle should be made available to the MSS whenever possible for maximum diagnostic efficiency. In some instances, antenna or coax cable problems can only be detected if the vehicle is provided to the MSS. By dialing 1-800-331-6456 (outside of Illinois) or 1-312-576-0428 (inside Illinois), information regarding the location of the nearest service shop can be obtained. Phones are staffed from 8:30 to 5:00 Central Standard Time.

#### Placing Calls

When servicing a cellular mobile telephone system, diagnosis may require the placing of telephone calls from the cellular phone in order to identify the condition. These calls should be made to the dealership switchboard or other local destination and should be very brief. The owner should be advised of this procedure and informed that a small charge for the call will appear on their telephone bill. This procedure should also be followed if the phone is tested before the owner first takes delivery of the vehicle.

The Dealership should be ready to provide the information below to the Cellular Telephone System Operator in order to establish customer telephone service:

The System Operator will provide the data below once the dealership has supplied the information on the Telephone Number Acquisition Form (see page 6):

#### NOTE: The dealership should keep a copy of the Telephone Number Acquisition Form and the System Operator Data Form in the vehicle history file for future reference.

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.
