Guys,
I have just purchased a 2001 Corvette Coupe with Auto Transmission. According to the dealer service records, the column lock recall has not been done. Since the car has been serviced at the dealership numerous times, why wouldn't they have done? Is it possible that not all vettes required the recall?

Thanks,
Rick.

 

Starting in 2001 and through 2004 the A4 cars did NOT have the column lock problem. On 2001 - 2004 only the manual trans cars had the issue. On 1997 through 2000 all cars had the Column lock issue.

 

Great news. Thanks for your reply!

 

At least GM finally got it right on the A4 cars.

 

The column lock problem went from 1997 till 2005.

 

Actually the problem still occurs on manual trans C6's through 2010 (may also be on the 2011's). Unfortunately there is no CLB solution for the C6. You end up replacing the lock motor which is an expensive solution. Do a search on the C6 boards for "column lock" and you will see plenty of posts about that issue.

 

A Federal Law requires that the ignition emobilize the car as a theft protection. Manual trans C5's lock the steering column. Automatic C5's (after 2001) lock the auto trans shifter lever.

GM actually got a waiver on manual trans C5's to NOT lock the steering column.

 

That waiver actually came at the end of 2005 after the C5 had been out of production for about a year and a half. As a result of that waiver they were able to implement the 04006C variation of the column lock service that replaced the larger diameter lock ring with the smaller diameter lock ring used in the A4 cars. A partial blessing for those C5's that had chronic column lock problems. Partial blessing because while the column no longer locked they still experienced the fuel shutoff symptom.

 

I missed asking this question in another Column Lock Thread. Before I ask so that you know I most recently had my vin checked for me by Gene Cully on my '99. From what I can see GM delt with the column lock issue twice on it during servicing. My '99 is a manual 6spd by the way. I have only had the car now for a month and a half. I haven't had any problems as of yet but can hear the column lock after turning the key to the off position when shutting down the car. At that point the column is definitely locked. Put the key in the start position and I can hear the pin slide over. If GM truly repaired my car were they suppose to disengage the locking mechanism for good? To play it safe I purchased a CLB recently from Corvette's of Houston that I have in my possession now not knowing whether to install it or not. Not knowing exactly what GM might of did or touched is another thing especially if their fix was to add something else to my system other then what the directions for the CLB states. Below is a copy of my GM VIN Check for all to see. Maybe someone will read it differently that I am reading it on the Column Lock issue.

Your car has the early variation of the GM service, 04006 (other variations are 04006A, 04006B and 04006C (replaced the lock ring)). The date of 04/19/2004 is evidence of that. I have the first dates for the other variations but need to look up where I saved them. Your column still locks with NO KEY in the ignition. Car should NOT have the spliced purple wire and relay mod in the passenger footwell but should have the GM K Harness in series between the lock motor and BCM (unless a previous owner removed it because it failed) If you trust the lock motor to continue to work you can NOT install the CLB. But if the lock motor decides to go out in the locked position (there are plenty of documented cases on the forum) your column will lock and you will experience the fuel shutoff. If you install the CLB then the lock motor gets disconnected and you don't have that issue. However if the battery goes low you can still experience the fuel shutoff. If you do decide to install a CLB then be certain to disconnect BOTH ends of the K Harness and plug the CLB into the female connector attached to the bottom of the dash.

 

Hi There 8VETTE7,
I found this report in my corvette folder.GM Vehicle Inquiry System sub titled labor operation.
Repair order date
04/07/2006 replaced n2030 back-up lamp switch 6spd 8,399 miles

04/07/2006 replaced left h/lamp actuator assy. 8,399 miles

09/02/2005 replaced body control module 7692 miles

09/02/2005 v1145-04006-perform reprogram & functional test on manuals. 7692 miles

08/28/2002 align. rear bumper fascia 2997 miles

These items were performed at Kerbeck's in Atlantic City, N.J. I bought this car from the original owner in New York in Dec. of 06. The above items were the only problems he had. 9000 miles when I bought it. I had the GMPP major guard.I never had any of the usual problems with this car.
Gm's letter about this problem to the original owner is dated feb. 2006. Current mileage 22413.

The date 09/02/2005 corrolates to variation 04006B of the GM recall service.) 4006C did not become available until late Jan 2006. The major difference between 04006B and 04006C is that GM was now allowed to replace the lock ring with the smaller diameter lock ring used in the automatics. (lock pin can no longer intercept the lock plate so the column will never physically lock although the BCM continues to send lock and unlock signals to the lock motor.) GM received the waiver to no longer have a locking column in a manual trans on the C5 at the end of 2005. Prior to the waiver there is a federal law that requires a manual trans car to have a locking column as an additional anti-theft feature. The waiver applied to all 1997 - 2004 C5's that have manual trans. If your car had been taken back into a dealer after 01/2006, and you complained loudly enough, the dealer may have done 04006C at no charge. GM stopped ALL free column lock service IF the car had already had at least one NHTSA recall service performed at GM's expense, in Mach 2007. So if you took the car in now and have already had one NHTSA recall service done on GM's tab, you get the priviledge of paying for any further column lock repairs/service. Your car has had 2 services based on the info you have presented here.

 

Hi There 8VETTE7,
Thanks for the in depth info.Thats just what I was looking for. I wanted to know what was done on versions a,b,c. I will e-mail the o/owner & see if he went back to Kerbeck's in 2006. I doubt that he did as he was really sharp on all the paper work with this car. There is so much thats why I could not find it(GMVIS) right away.
Thanks again.

I am pretty sure your quote above was directed to both of us being we seem to have the same code 04006 dated for 4/2004. Question: Is this K Harness plugged into the same place where the CLB is to be plugged into? Does anyone know what this K-Harness looks like? Sorry I am not very familiar with this part of my C5 as of yet. Always have been a C2 and C3 guy before this, computer free.

 

Sorry, I should have stated both of you. :o Here is what a K harness looks like:

http://forums.corvetteforum.com/c5-g...l-locking.html

Then scroll to post #8

It is easily recognised by the female connector that has only 2 wires, 1 white and 1 purple. If it is installed it is behind the drivers side knee bolster and is in series between the column lock motor and the BCM. Male connector from the column lock motor (wires appear to go up into the column) is plugged into the female connector of the K Harness and the male connecftor of the K Harness is plugged into the female connector that is attached to the bottom of the dash. Here is a link to a good set of CLB install instructions that has both pics and words. The first part of the instructions deals with dropping the knee bolster and identifying the female connector that is attached to the bottom of the dash.

http://www.ls1howto.com/index.php?article=24

To install the CLB you first get the column unlocked (cigarette lighter adapter tool that comes with the CLB will do that), then you connect the CLB into the female connector that is attached to the bottom of the dash. Finally clear any error messages in the DIC and any DTC's set in the BCM.

Your 99 manual trans MAY have the spliced purple wire in the passenger footwell. Here's a link of what to look for:

http://forums.corvetteforum.com/c5-t...please-52.html

Then scroll to post #1030

If you have the spliced purple wire and relay mod, you MUST bypass the relay in order for the CLB to work. Here is a link on how to bypass the relay:
