New DBS info NOW
'06 manual
Won't start. Has not been driven since Sunday night. Today at 11:30 am...no start.
Solenoid chatter coming from the steering column area of behind steering column. Chatter is very low in intensity and may be a dc motor hum. The low voltage is masking it.
I can disconnect my neg cable to remove chatter and reconnect - chatter still present.
This tells me the condition that caused the DBS is still there. I called my dealer and they had me call roadside. I am waiting for roadisde to get the car and take it to the dealer.
I explained to the Service mgr that this may be the best field condition that GM has had to troubleshoot DBS and they are waiting. Hopefully they are smart and know how to troubleshoot.
I don't know for sure obviously, but I would guess that the column lock motor/solenoid is engaged due to a faulty limit switch or maybe the BCM (don't remember what GM calls it, my old company calls it a body control module) is keeping it engaged. I forgot what GM's circuit looks like for this and had no need to remember it in the past since I was only listening and trying to help with DBS but never had one.
Will keep everyone posted...

BU2005 & BU0005 means your Steering Column Lock is malfunctioning causing the DBS If I remember right you have to error out at least five times before the protective mode sets in and blocks the restart. Trying turning the steering wheel a few times to free up the lock.

So you were actually able to enter the car without going to the trouble of using the key at the hatch and pulling the manual cable to open the car door?

It wouldn't be the first C6 to have the SCL itself go south, but it still may yield some clues as to the cause of DBS. .
Here's hoping you get things worked out...

I could not enter the vehicle, and nothing electrical functioned...I entered using the trunk access door release.
Whether this is a typical DBS or not, I don't know. Nothing worked on my car except I heard the solenoid chattering (faintly).
There IS a known issue with the column lock solenoids. The failure causes the battery to run down.
I'm inclined to believe that this was indeed DBS, even though there was still power to the solenoid after 2.5 days, nothing else on the car worked.
