Condition

Important

This Service Bulletin only applies to vehicles that are NOT included in Customer Satisfaction Campaign 00104A Corvette Electronic Column Lock.


Some customers may comment that the electronic steering column may not function as intended. The condition could result in the failure of the steering column to unlock during initial key-in and start-up. The customer may also comment on a "Pull Key, Wait Ten Seconds" or a "Service Column Lock" message appearing on the Driver Information Center. Should the column fail to unlock, the PCM will disable the fuel to the engine, limiting the vehicle to approximately 3 km/h (2 mph).

Correction

The required repair varies depending on the model year, transmission and if the vehicle is domestic or export. Please refer to the chart below which outlines the proper parts to install with each combination.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these 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 your GM dealer for information on whether your vehicle may benefit from the information.
