One of the first installation steps is to physically disconnect the motor that drives the column lock, so it is impossible for it to power up and engage. As stated above, you could get a bunch of codes in the computer and not sure how the car would react to any codes, but the steering wheel won't lock.
Actually, I think I can shed some light to this subject. My friend (also a CF member) and I recently bought and installed CLB's in our cars. However, his CLB was damaged (some of the wires had pulled out of the harness, wish we would have noticed beforehand) and when he put the vehicle in motion it cut the fuel to the car. So based on this, I would have to say that if the CLB malfunctions that it would cut the fuel, but it would not engage the lock.

The same thing happened to one of the cars we did (it was the wire wire) it cut off fuel, so a word to the wise , ck the wires where they enter the units, apparently sometimes the crimps are bad.

I haven't had one of the steering column locks apart to see just how it works, but I think it is your typical 12 vdc electric motor with a worm on the shaft driving a worm gear that drives a screw mechanism that moves the locking pin. When the CLB is installed the CLB can not be powered electricly but if the motor armature were to rotate due to vibrations while operating the car the pin might be extended out enough so that it could come in contact with the lock plate and possibly cause the steering wheel to lockup. The GM recall on the 97-00 elimanates this potential problem. This is why I had the recall done instead of the CLB on my 98.
