STARTING DISABLED DUE TO THEFT SYSTEM MESSAGE

MODELS AFFECTED: 1989 ELDORADOS, SEVILLES, AND ALLANTES

Some 1989 Eldorados, Sevilles, and Allantes may experience a condition of the "STARTING DISABLED DUE TO THEFT SYSTEM" message being displayed on the Driver Information Center when some ignition keys are used.

This condition may be due to a damaged or incorrect ignition key. Some vehicles may have been built with mismatched key sets. That is, all of the ignition keys do not carry the same electrical code, even though the mechanical cut is identical.

When diagnosing any conditions with the PASS KEY system, it is important to verify that the condition is present with all of the ignition keys. If the condition is present with all ignition keys, diagnosis should follow the procedures outlined in Section 8A-133 of the Service Information Manual. If the condition is present only with selected keys, those keys should be replaced.

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.
