Perhaps, however, given the absence of any other found cause and because of the profound reduction in DBS in MY06-07 cars with SCL removed, my money is with SCL or problems stemming from SCL. Nevertheless, the real shame of all this is GM and Delphi are no longer actively looking for a solution and they are leaving the problem up to the dealer techs' to sort it out. If you are a good Tshooter you may find what is happening, but my advice to anyone with chronic DBS is to get a deep cycle battery that can take DBS abuse-Ciao!
Really I thought they WERE working on it By the way what model of OPTIMA is getting the best reccomendations?

Really ......I tought that they were making some progress Anyway what model of Optima do you guys reccomend?
Thanks for everyone's insite...I fear I have the DBS
Few things:
1. I stored my car over the Michigan winter (battery disconnected) and went to start it up a couple weeks ago but battery was dead...charged it and started right up for me to change the oil (only 2700 miles).
2. Drove it for about an hour and parked for approx. 10minutes...battery was DEAD.
3. After several more incidents battery still required jump start to turn over...finally took to dealer yesterday.
4. Dealer had never heard of DBS and diagnosed my problem as a dead battery (no kidding!?!?!!). Swapped out with new and drove home.
5. Car sat for about 3 hours...got into car to pull it into garage and BATTERY was dead...brand new battery!!
And before you ask, yes! I followed the proper shutdown procedures as usual.
LASTLY...what is this part everyone is talking about for their SCL? I do get the SERVICE COLUMN LOCK message while driving!! Weird or what?

Most likely not DBS. DBS takes more time to happen, unless the battery is already way low.
I suspect your battery is still the culprit and needs a more complete charge.
Of course make sure that nothing is left on like dash lights or anything aftermarket.
Service column lock is one general message that seems to come across when dead batteries are coming back to life.
If your getting that message while driving, then you may have more of a problem. Is the dealer aware of that?

Really.... I thought some earlier posts indicated that GM had some sort of "team" working on this???
Ok, so here comes the dumb question of the month: Theoretically, what would happen if the '05 BCM were replaced with an '06 BCM? In other words an '06 BCM in an '05 car?
Hmmm posted but it disappeared. Theoretically, what would happen if you put an '06 BCM into an '05 car? Never mind fit etc., but does the '06 just not have the "inputs" for reverse shut down and SCL?

Really......? I thought they had a "team" that was trying to help us out
Autocutter has said that GM "is no longer actively trying to figure this out............." I thought they had some sort of "team" trying to help us out on this

According to C5-Bruce they have some DBS prone cars under analysis at this time.
The only reason I mentioned the washing bit was that when my DBS started and that several members have stated a similar onset. I washed my car in my drive which has a 8% incline; when I finished I got in to the car to pull in to the garage, but nogo/no start. .........
Amazing. I had the exact same thing happen just yesterday and before I read your above post.
My driveway is on an incline, I washed the car, finished up. Car opened as usual, everything lit up, except when I hit the start button, nothing. Hit it again, nothing. I was in on the clutch, the car was in reverse and nothing. Finally after the third attempt it fires up.
I have only seen this happen one other time when I stalled the car out in my development while leaving a stop sign.
Pushed in on the clutch and hit the start button, and nothing. Took two attempts to get it to fire up
You're obviously into the electo-mechanical details more than I.
My view is mostly anecdotal and non-technical.
I'm sure you're aware of my proposal about a defective reverse sensor causing DBS, stemming from the fact that my DBS prone car can get the DIC warning 'shift to reverse' despite being shutdown in reverse.
Today I got an email about another DBS prone '05 MN6 with this same characteristic.
Could it be that the SCL is upstream of the reverse sensor in the shutdown process, and may actually be the part that is hanging up, delayed or defective, and not the sensor itself?
I'm a computer programmer, so this problem was too hard to follow from a logic standpoint. That said, I look at DBS like I do a copy machine gone bad with too many electro-mechanical parts making TShooting real tough. The reverse sensor is actually two switches in the trannie that are triggered by a dog leg shaped lever. If that lever is just out of line a bit or the switch is not in the right place, then one or switches might not be activated and indeed that may be your root cause of DBS. As I remember it, one switch is for the DIC while the other is for the ECM. The switches are connected to the wiring harness externally and the connectors can be switched for one another. I need to look at the service manual to give you an exact location. As to whether who comes first during shut down, if I remember right the switches comes first(the car is at home today elsewise I would try the shut down out of reverse to see if SCL fires when not in reverse.)

Thanks for the reply.
The column will not lock on shutdown until the tranny is placed into reverse. (I just checked)

Go left and right fairly hard on the steering wheel; or hold your FOB just left of your radio and press the start button. The first suggestion was how they finally got the car to work before replacing all the SCL guts-which was after the GM Engineers finally told the Service Manager that the car shuts it self completely down until the SCL total failure was unlocked and repaired.
I got the car to start several times by the 2nd suggestion(I have no idea why it worked and neither did the GM engineers from Bowling Green who were celling in with the Service Manager when he came out with the Tech2 to diagnose and work on the problem)
Hey ..... sorry about all the multiple posts......I kept trying to post a reply and every time it "disappeared." Never showed up on the thread screen...........now all of a sudden they are all there Beats me......

The forum's computers were messing up yesterday.
If you still have trouble go into your CP options and change your default forum view to 100 posts...
Thanks for the reply.

Just home and checked and the switches are first. Checking the manual shows switch #1 goes to SCL/anti-theft system while switch #2 covers the ECM so I was wrong saying the first went to the DIC(I should have remembered that as the DIC only receives info from the LAN. )
As far as GM DBS team goes, has anyone more actually been officially contacted in the last few months? I mean DBS and SCL problems are not a secret, both have seen a little magazine time, and certainly most dealers have had one or two cars with the problem. I'm finding it very difficult to believe that since August 2004 that GM has not found the actual cause or causes of the problem. In any case, none of my GM contacts have heard of TShooting beyond the local level, but there again GM is so big that one half of the company could be putting someone on the moon and the other half of the company wouldn't ever know that it was happening

C5-Bruce at least had some contacts. That's all I know.
