Why is GM still programing the fuel cutoff if they are removing the column lock plate? It makes no sense, if the column can't lock there is NO chance of driving with it locked !

BTW, I have a 98 MN6 with a COH CLB installed and NO GM recalls done.

 

The recall letter I got stated that the car was always programmed to cut the fuel if the BCM could not determine the position of the actuator, or determined that it was in the locked position.
On my 04, the lockplate was removed but no mention of a re-program to cut off the fuel.
Maybe people are confusing earlier recalls that may have involved a re-program of the BCM with the last recall on the manual cars to just remove the lockplate and bypass the actuator.

Here is a quote from the letter:
"Reason For This Recall: General Motors has decided that a defect, which relates to motor vehicle safety, exists in all 1997 - 2004 model year Chevrolet Corvette vehicles equipped with a manual transmission and certain 1997 – 2000 model year Chevrolet Corvette vehicles equipped with an automatic transmission. 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 system. Two conditions can prevent steering while the vehicle is moving:
1. Your vehicle is designed so that if the column fails to unlock when you start your vehicle, the fuel supply will be shut off if you try to move your vehicle. If voltage at the powertrain control module (PCM) is low or interrupted, however, the fuel shut off may not occur and the vehicle can be accelerated while the steering is locked.
2. 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."

I do remember reading about a re-program of the PCM, but that was to correct a problem in communication between the BCM and the PCM under low voltage conditions. Under certain low voltage conditions, the PCM would not receive the signal from the BCM to cut the fuel, which could result in the car being driven with the column locked.

 

Thank you for that clarification. I thought that GM programed the fuel cutoff as a part of the recall, not that this was always programed into the computer.
