SERVICE MANUAL UPDATE-SEC. 8D DIAG. PHONE MODE DISPLAY BD45

VEHICLES AFFECTED: 1990 E

Diagnostic parameter BD45 "Phone Mode" will be displayed only on vehicles with the optional Visual Information Centre (U68). Vehicles without the optional display will not display BD45 regardless of the presence of a factory-installed phone.

Please note this correction in you 1990 Service Information Manual (NPI page 8D-15 or Final Edition 8D-18).

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.
