--------------------------------------------------------------------------------

THIS BULLETIN CANCELS AND REPLACES BULLETIN 04006B, ISSUED NOVEMBER 2004.


--------------------------------------------------------------------------------

THE SERVICE PROCEDURE FOR U.S. VEHICLES EQUIPPED WITH A MANUAL TRANSMISSION HAS BEEN REVISED. PLEASE REVIEW THIS NEW INFORMATION IMMEDIATELY.


--------------------------------------------------------------------------------

ALL COPIES OF BULLETIN 04006B SHOULD BE DESTROYED.


--------------------------------------------------------------------------------

Condition
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 1997-2004 model year Chevrolet Corvette vehicles. When you remove the ignition key, the electronic column lock (ECL) system prevents turning of the steering wheel. When the vehicle is started, it unlocks the steering. Two conditions can prevent steering while the vehicle is moving:

The vehicle is designed so that if the column fails to unlock when the vehicle is started, the fuel supply will be shut off if the driver tries to move the vehicle. If voltage at the powertrain control module is low or interrupted, however, the fuel shut off may not occur and the vehicle can be accelerated while the steering is locked.
During quick cranks, the ECL lock pin may not withdraw fully and, in vehicles where there is abnormally low clearance to the lock plate, there may be contact between the pin and lock plate. This can cause a noise or ratcheting when the steering wheel is turned, or if there is insufficient clearance, the steering wheel cannot be turned.
If one of these conditions occurs, a crash could occur without warning.

Correction
Dealers are to remove the column lock plate on U.S. and Canadian vehicles equipped with an automatic transmission and U.S. vehicles equipped with a manual transmission. After the service correction, the steering column will no longer lock when the key is removed.

On Canadian and export vehicles equipped with a manual transmission, and export vehicles equipped with an automatic transmission, dealers are to 1) reprogram the PCM, and 2) verify there is adequate lock plate clearance and, if necessary, replace the lock plate. After the service correction, the steering column will continue to lock when the key is removed.

Vehicles Involved
Involved are certain 1997-2004 model year Chevrolet Corvettes equipped with a manual transmission, 1997-2000 Chevrolet Corvette equipped with an automatic transmission, and 2001-2004 Chevrolet Corvette equipped with automatic transmission (European export only), built within these VIN breakpoints:

Thanks for you response. Are the numbers quoted with the 2004 in reference to the vin #?

I went to the Paradise Chevrolet stealership last weekend and requested to have the column lock removed. The service writer looked at me like I was from another planet. I told him that I have the complete bulletin from GM at home if he wanted to read it. Just a blank stare. :( He did not even want to check in his computer to find out what outstanding recalls there were on my car. I gave up and left.

Anyone on this forum have the 04006C recall done at Paradise Chevrolet in Temecula California yet? I don't want them to experiment on my car trying to figure out how to remove the steering lock for the first time.
