Could Battery Disconnect Cause Column Lock??
Was reading where one possible cause of the dreaded CL failure could be low battery voltage. Would this include removing the battery...or the negative terminal??

What they are referring to is the reason why GM modified the PCM code (that a dealer will flash into your car's PCM during a CL recall procedure) to cover their tracks.
Has nothing to do with "creating" the condition; simply making sure a CL motor failure "event" doesn't slip by the PCM's logic due to a low battery condition.
If you read the text on the GM recall, this will all make sense to you. If it doesn't let us know and we will clarify.

Several weeks ago stupidly left the ignition on after I finished some work on the car. The next day I went to start it and the battery was dead. After recharging the battery I tried to move the car and everytime I let the clutch out the engine would stall. The column lock was unlocked since the key had never left the ignition so I thought maybe the BCM has forgotten where the lock bolt is. So I got out and removed the positive battery cable for a few seconds and the car has run fine since then.

as weird as it sounds I will tell you my experience.
My serivce CL came up on my DIC, but it had broken in the UNLOCKED position!! woot I got lucky. Well as I was waiting for my CL bypass to arrive I was installing a subwoofer and amp and I had to disconnect the battery. Well when I reconnected the battery when I was done my Column Lock mysteriously started working correctly. It stayed working until a couple days later when I put the CLB in.
Strange.....but true.
