I was thinking about getting the PCM reprogrammed anyway, just in case my CLB ever fails. Some posts back I read that if you have the fuel cutoff disabled for the column lock, that it also disables your rev limiter fuel cutoff??? Sounds somewhat dubious to me, if they tied the programming of those two things together the programmer needs to be fired, but anyone know if this is fact or fiction?
Another thing that might be useful for folks with my exact problem and car... one of the things I was not able to figure out from reading the posts was whether or not the CLB would work once you did have an error message. There were many posts stating that you have to get the CLB before you get a problem, but they were not clear which problem they mean. What I concluded was, if you have a MN6, and if you had the recall done and had the locking plate removed, and then your locking motor decided to quit working or quit sending the correct signal back to the BCM, causing the fuel cutoff issue (but no locked column because you don't have a locking plate anymore), then installing a CLB will work for you. You can even skip the step of using the cigarette lighter plug to unlock the column because it doesn't matter anymore, but I did it anyway, it took an extra 10 seconds. If you did not have the recall done to where your locking plate is removed and your column is permanently locked, you would have to unlock it somehow before the CLB will work for you. In another thread someone mentioned that they basically broke open the lock and removed the pin as part of the CLB installation. Automatics are a different story I think, it seems for the recall they do something different than for the sticks.

Any thoughts/suggestions?
Take care.
My 97 that I've owned for a year, did the column lock thing back in the beginning of March this year. Dealer played dumb, so I checked the forum and found out about the recall, called them back and had it fixed at no charge. I have no idea what they did. (BTW, the tow truck driver pulled my battery and reset the system, releasing the lock so I was able to drive it to the dealer, saving a hefty trailering charge.)
Anyway, yesterday got the dreaded "pull key wait 10 seconds message" which eventually fixed itself after three tries. Called service guy and he said, hmmm, don't know what could cause that. Now I'm worried to take it back to them since they don't seem to know what's causing it. I'm a non-mechanically minded girl and mechanics see dollar signs when I pull up. I want to be somewhat educated when I call them back. Thanks for any advice. ...................
So there's my story, again, if someone could give me some clearcut details to give the service guy, it would help. Me personally dealing with fuses and K things and other technical stuff is not an option, unfortunately. Again, thanks for your help.
Good luck.

My dealer did my recall back in 2006. I didn't really want to but figure it wouldn't hurt since I was there for something else. I dont' have the lock plate anymore. They didn't touch my programming since my tech though I might have a non-stock tune.
So, I busted out my HPTuner today and downloaded version 2.2 after doing some reading. I was running 1.7, which doesn't have the column lock option. I found the "Fail FuelCut VSS" set for 2 mph like other have mentioned. I bumped it to the max, which is 256 mph and also set the column lock to "Not Fitted". At least, I can drive the car now faster then 2 mph
. Now, I'm hoping the CLB will get rid of the "Service column lock" and "Pull key and wait 10 seconds" problem.
Is there any reason for me to get a CLB at this point?
1. I bought my 2001 M6 in late 2006 at a Nissan dealer (he took it on trade)...great car in great shape with really low mileage. I had all the records (so I thought), and didn't know of any issues.
2. About a year ago, my car started and the column stayed locked (with no message) -- I was able to get it to unlock with the "tug and pull" method on the wheel. After I got home, I did some light reading here and decided to get a CLB. I installed it, and thought all was well, as the column lock no longer engaged.
3. Recently, I had needed an oil change for about a week (and had an oil change plan that came with the car from the dealer), but had been swamped all week with work, getting ready to deploy, and planning my son's Eagle ceremony (side note: real proud of the boy). Anyway, on Friday I finally found a spare hour, and ran down to get the oil change...they got it right in and made sure I had the right oil, etc. It was taking a while, and I saw my technician keep going back and fourth talking to the advisor, so I went to inquire. He said when he pulled it off the lift, it died and said "service column lock." I thought I was smart, and could make it work...even disconnected my CLB, but no dice. UGGGHH...didn't need this. Well my advisor was a former Chevy guy and was able to get me a complete report on my car and the recall...turns out it had been done on my car in spring 06 (version C -- important note later).
4. I called the dealership who did the work and explained the issue, and he said it was a sensor that went bad, and he was a vette guy, and had seen it before. He said there are only 3 left in the country, and it cost $800...WTFO??? Anyway, figured him to be an idiot, but he also stated once the recall is already done, GM won't do any more for it, and I had to pay (even if the recall was not done right). He said tow it in, and they would look at it. Well, I was bingo on time, so the Nissan dealer let me just park it there overnight.
5. The next morning, I had a couple hours before the ceremony, and did some research on this thread. I didn't read too far in (about 8 pages), and then skipped to the end. According to my reading, the recall only reprogrammed my computer (01 M6), and nothing else was done. I had concluded it may be a quick fix to"resync" the BCM by pulling fuses. My son and I went up and tried every trick I had found...pulling fuse 25, fuse 23 (heck, I pulled all the BCM fuses). Did it for 10 secs, and left them out for 10 minutes while we went and got Starbucks...no dice. I even reinstalled the CLB using the original procedures...still nothing. Gave up and went on to enjoy the rest of the day with my son's accomplishment.
6. So today of course...more research. I finally realized, my early reading were of posts prior to Feb 06 when version C of the recall came out requiring the dealer to install the K harness on ALL manuals. Then I read there were several of those harness which had failed, and many people had just taken them out of the loop. So....I hauled a$$ up and did that very thing...put her back to TRUE STOCK, reset the BCM (fuse 25)....and....wait for it....BAM, BACK IN BUSINESS!
So now I am going to put my CLB in without the K harness so the lock no longer engages.
I am glad to get my car back to the house...and it is driveable -- didn't want my wife to have to deal with it while I was gone.
The Best of Corvette for Corvette Enthusiasts
1- remove the steering wheel, locking plate, and the bracket that houses the locking mechanism (and the wiper motor switch).
2- Remove the locking mechanism from the housing (remove one screw and shave off the edge of the housing pressed against the locking mechanism).
3- Reinstall the empty bracket, locking plate, steering wheel...
4- the Body Control Module (BCM) expects a "Unlocked" signal from the missing locking mechanism through the green wire. The locking mechanism has (had in this case) a micro switch that connects as the locking pin reaches its Unlocked position connecting the green (BCM "Unlocked" signal) to the black wire (ground). Grounding the green wire will not work for the BCM software expects a ground signal from the green wire as the ignition switch reaches position 1 (Accessories).
5- Install a simple four-wire relay as follows: the two solenoid (skinny wires that create a magnetic field and cause the relay to click as the main contacts come together) one solenoid wire to ground, the other to a positive feed when the ignition switch is in position 1 (Accessories) and position 2 (Ignition). The main contacts wires (usually larger gauge wires) connect one to ground the other to the green BCM signal wire.
Et voila! Top down, this 98 Corvette runs well and safely in Sunny Florida.
Cheers!
Edit:Ok found it. Expired on Feb 29th? How does a recall expire? Are they still supposed to honor this? I just want a pcm reflash so I can flippin drive...sheesh.

Took the car to the dealer yesterday, says everythings cool, they'll be happy to help me out. Service tech looks at it for about ten minutes this morning, and then I get a phone call. Apparently, there has been so much aftermarket wiring installed in my car (unbeknownst to me, there had been some major non-gm repair work done before I bought it) that the tech didn't want to mess with it and that I need to come get my car off of their property.
Well, seeing as the only way my ride has moved in about 2 months is on the back of a flatbed tow truck, I contacted my local tuner today and setup an appointment to have HP tuners remove this bull**** program. Thank you GM, my car has seen the last of a certified GM repair shop. We don't want to touch it? So much for standing behind your work, sad. And they wonder why people won't buy American.
Here is the main part of my story.
Well the problem is solved. The DIC this morning, started spitting out more random messages that had me, again, starting to question the integrity of the BCM. Plugged the scanner in to pull the codes and got the "no communication" message. started checking fuses again and I find one blown that had nothing to do with the issues but it did allow power to go to the OBDII connector to power the scanner without it's internal battery. I had noticed earlier that the power outlet was dead which is the same fuse. Anyhow, in continuing to check the fuses noticed a fuse that wasn't seated in all the way due to the fact that it was in crooked. Well low and behold, it's the BCM2 fuse! It is clear up at the top and not one of the three that everybody says to pull to "reset" the BCM. Wish I'd remember the number but it is irrelevant. There will probably never be another vehicle that will have this or any other fuse shoved in in such a way to cause a low voltage/intermittent connection. Anyhow, I pulled it out and shoved it back in correctly and all the sporadic messages stopped but the original three (two low tires, low oil, and the SCL message was still there on the DIC. THEN I Cleared codes with the scanner (snap-on Vantage) and the SCL message disappeared and upon driving the car the fuel cut was gone! Runs great! I guess the moral of this story is to scrutinize previous work, clearing the BCM doesn't always happen by pulling the fuse? At least didn't in this case, and frequently check ALL the fuses when diagnosing PITB issues such as this one. Not only the fuses but that they are plugged in straight and all the way, and that they are in the slot at all! I've had customers (and other Tech's), take a fuse out of one hole to power another) and WALA, a new issue!!! HTH Wish I could have found this post 4 days and seven headaches ago! I greatly appreciate all the information in this group that gave me the courage to even take this issue on! Wayne
It just takes time and or $$$ or both...comes with owning any car especially a toy...
Good Luck
In closing, thanks GM for building such a badass car but you could have spent a few more hours in the quality control phase, I toured the Bowling Green plant on Monday after the C5-C6 bash and while they seem to run a tight ship over there, there is ABSOLUTELY NO REASON we spend this much money on a car and have to deal with this kind of bull****. I mentioned my issues while on the tour and even the UAW boys knew about it, SAD. Their answer? "Hey we just put 'em in, its not our fault if the parts suck," which I have to say I agree with and understood. I'd like a personal letter from GM over this, and I'm sure I'm not the only one.










GM's column lock recall stinks.
I did end up removing the recall relay and used HPTuner to remove the 2 mph fuel cut off.



Btween this and the gas gauge!
