If the 01 an up A4's don't have the column lock on them, and we know that all the computer provisions are the same (like the TPM on the Z06 being turned off), shouldn't we be able to turn off the COLUMN LOCK on the MN6's via a TECH II? That option must be turned off on the A4's right?
I was hoping somebody who has a TECH II could look into this for us. It would be a great way to get around that problem.
Re: Tech II Question......Could Be Interesting (Bill Curlee)
The column lock is ~similar~ to the CAGS solenoid......and the CAGS solenoid can be turned of/disabled via programmer (Tech II, LS1 Edit).........and since the A4 doesn't have the hardware, you must be able to turn off that system........so all it would take is to plug up a Tech II and turn it off......I hope somebody with a programmer can try this out for us to see :flag
Re: Tech II Question......Could Be Interesting (Z06 Quin)
The column lock is NOT an option,only options can be turned on and off in the BCM via the TECH2 :yesnod: If it were that simple,GM wouldnt have recalled 30,000 C5's,requiring us to tear into the steering column to disable the column lock,as opposed to doing a simple program change :steering:

is the CAGS an option? I know it can be it can be turned off.....this was my train of thought.....also, I can see why they would have you tear into it vs. turning it off....they want it to work properly.... :yesnod:
Re: Tech II Question......Could Be Interesting (Z06 Quin)
The CAGS is not an option,and I would be interested in how one would turn it off with the TECH2???.GM would never give the dealers the capability to shut off an emissions related device,if you know what I mean ;)
The column lock ciruitry is "burned" into the BCM,much like your key pellet resistor,and the TECH2 does not have the ability to remove it or change it.The only thing that can be changed is a list of displayed options on the TECH2 such as twilight,seat memory option,HVAC,etc :yesnod:

The recall (or was it just a tech bulletin) was for earlier models. It stands to reason that since some later models (2002? and later) have column locks (MN6) and some do not (A4) that the column lock code would be configureable and not burned into the BCM. If it is burned in then A4s and M6s must have different BCM part numbers. Do they?
Re: Tech II Question......Could Be Interesting (C-5 TECH)
We have now found that the tire pressure module can be turned on with a tech 2 on a Z06, and that is not an option either. Don't know the answer, but Quin's train of thought has some precedent.
Re: Tech II Question......Could Be Interesting (jschindler)
C-5TECH,
I know for a fact that the CAGS can be turned off via either LS1 Edit or Tech II (don't know which)...because I was given a CAGS eliminator by a freind who didn't need it because his was programmed out....so it stands to reason that the column lock can be turned off as well......just thinking out loud here.... :cheers:

In ls1 edit you can program the cag's not to turn on till 255mph. It has nothing to do with the Column lock.Maybe with a Tech2 programming on a 2002 you can tell it to turn off the column lock.
I have been trying to deprogram my tiresensors for months.
Re: Tech II Question......Could Be Interesting (Wicked C5)
Here is the list of options that can be deactivated or activated in the BCM via the TECH2...
Country of Sale (US, Canada, Europe, Japan, etc.)
Real Time Damping (RTD)
Memory Options
Front Fog Lamps
HVAC (C60-Manual, CJ2-Automatic)
Active Handling
Auto Headlamp Control
Power Tilt/Telescope Column
Unlike LS1 EDIT,the TECH2 does not have the capability to change parameters in the PCM (unless GM releases a program update to do so)...CAGS is controlled by the PCM,not the BCM,which controls the column lock.The TECH2 only has the capability to change the above options listed.The BCM is not as smart as the PCM,it simply works like a bunch of relays in a box...The question which was posted earlier is if the 2001-03 M6 and A4 BCM's are different part#'s,which I will find out tommorow ;)
You may be interested to know that the 2001 A4 has all the column lock wiring in it,right up the the steering column.The decision to delete the column lock must have been during production :eek:

I don't see TPM in that list.....I and quite a few otherZ06 owners have turned ours on via Tech II......installed the sensors and it all works fine.
I didn't know how the CAGS was deleted by programming, but changing the trigger speed makes sense.
It was just a thought I had on the Column Lock....thought that since the A4's didn' have it it could be possibly turned off on the MN6/M12's
Re: Tech II Question......Could Be Interesting (Z06 Quin)
In my rather limited experience using a Tech2, it would appear that only RPO options can be toggled on or off. In addition, only those RPO options that are available for your specific year (any model ok) can be toggled on or off. That's not to say you won't need additional parts to turn a particular RPO option on and have it work...sometimes you do and sometimes you don't.
The reason that you have to take the specific year into account is that there has to be a model in your year available that has the option and another model that does not. Hence, you can turn the tire sensors on in a '01+ ZO6 or off in a '01+ coupe but you can't turn them off in earlier years because they all had them.
With regard to some related option (column lock) that a 6-speed has and a A4 does not, I don't know. My guess is that since it's related and standard to each transmission (not model) you have, there is no toggle available. When I have the opportunity to hook my Tech2 up to a '01+, I'll check it out.
