I just got the dreaded "Service Column Lock" on my DIC and the car won't start. I thought this problem was confined to the C5s. Any words of wisdom other than having it towed? Thanks.

Battery may be too weak to start the car.

I think you're right ... I just came in from checking the voltage & its only 11.2 V. I've got a charger on it. Now if that is all that it is then I have to ask why the voltage went down after sitting for only 2 days. ?

I hope to God that I don't have to go through this again in the C6. My temper about tore the hell out of the C5 jerking the damn wheel loose so many times before finally getting it fixed.

It wasn't the column lock, even though the DIC said that. The battery had only 11.2 volts so I charged and jumped it and now many hours later I am hoping it will hold the charge. I'm not sure why it would say "Service Column Lock" when the voltage is low. (Its a 2005 C6 with delivery in July.)

This looks more like the DBS problem. I DID have the 6 spd tranny in reverse. I carry a set of jumper cables in the car at all times because this happened once before.

Service Column Lock is a message which commonly comes up when the battery is in it's death throes.

C6s do not have the column lock issue that C5s had.

Yes it does! I got it at 2200 miles!

I have read of a car recently with serious column lock related issues. But this is highly unusual for a C6 and not common like in C5's.
Can you give us more details on your problem?

KGB6

The electromagnet column-lock mechanism, which is also used in the C5, failed. It took two towing trips to the dealer for them to catch the problem, and they had the car for nearly two weeks because of lack of parts.
The column-lock will likely fail at some time in the life of the C6, and when it does the car will need to be towed. The car will not start, nor can you turn the steering wheel, when the column-lock fails.

If you have an actual column lock on a 2006, then you have a rare bird, because it was removed after model year 2005.

It does seem that the DIC message itself, however, still exists in the software, and as was prevously explained, this message seems to occur preferentially when the battery voltage is low.

I have a 2005. GM got rid of the column lock on 2006 C6.

Your column lock failure is very rare in my experience on this forum. The C6's have been out for about 20 months.
Just why do you say 'likely' failure?

Dear all, my 2010 C6 suffers since a while from this "Service Column Lock" message. Pressing the start button kills the car totally. There is no more power from the battery.
What helps?
Hard to say: Sometimes it helps to press the RESET button in the dashboard. Sometimes it helps to try to start again.
What always helps is to unplug the battery for a minute and then it always works.
My battery is just one year old and works fine. Leaving the car in the cold winter for 10 days and it started perfectly.
Nobody knows what to.


Does someone of you have an idea?


Thanks very much in advance and greetings from cold and sunny Germany.

the 05 manual transmission C6 car does have column lock issue

irok

it wont be a column lock problem because your car dosent have one.check cable connections at starter

A 2010 C6 is not supposed to have a column lock solenoid. Only the 2005 year model did. Having said that, I checked all the wiring diagrams, and although it doesn't show up in the starting circuitry (attached), I did find it in the power distribution circuit (attached)

I would be rather shocked if your 2010 has the column lock circuit still in service, although nothing is impossible.
If I were you, I would check the Blue connectors of the ECM under the passenger carpet. Those can be dislodged by passengers that push too hard, and can cause some strange alarms etc.
Check the other things that may cause a non start, like the start button, the clutch pedal switch, etc.

Check other stuff as noted. Cable connectors at battery, starter, etc.

Good Luck

Thanx very much to all for the support. I keep you updated.

I’m at a loss, my 05 C6 is sitting in my driveway with tarp over the windows and a car cover over that. I’ve bought two bypass’s and neither one has unlocked my car, the battery is a month old , 99% charge and I’ve trickle charged for two days , nothing. I don’t know what to do, I believe I’ve followed all the steps I’ve seen on here but to no avail. Someone in plain English give me a remedy. LOL
