Tell the dealer to come tow your car in and remove the faulty K harness, then buy the CLB.
Is your column locked? It shouldn't be if the recalls were performed.
Try to remove fuses #25 and 29 from the passenger foot well and see if the messages on the DIC were reset. I believe your ingition has to be turned to "on" and do not start the engine.
Mine, as in many vettes, had a faulty K harness. I had mine removed and now I've got the CLB installed. Good luck.

Yes my column is locked. How can I make sure the recalls were done?
Also, when I put the key in and turn to on it says "pull key wait 10 seconds"
Than after that try to restart and the message service column lock displays.
Thanks

If your column locks then you do not have the latest recall performed. To get you column unlocked you must pull the steering wheel somewhat hard to the left or right, almost a hard jerk. Eventually it will unlock. Do a search on the forum as others have unlocked their columns in this manner. Once unlocked install the CLB if you can get one in a hurry. Otherwise you need to drive or tow it to your dealer.

Have you tried to remove and reinstall fuse #25 while the ignition is turned to "on"?

Is there anything else I can do to get it unlocked???? I've tried to jerk the wheel, pull the #25 fuse and cuss at it. Am I missing something.
Any other help would make my day.

Thanks

Lean on it hard to the right while you turn on the ignition. CLB will do nothing in your car if you had the recall. Get a tuner to turn it off with EFI Live.

"Tact" has it right.
If the latest recall was done, the lockplate should have been removed and the column should no longer physically lock.
If you do not trust the relays in the GM Harness K, you can remove it and replace it with an aftermarket CLB.

The relay in the Harness K and the relay in the CLB peform essentially the same function, except the Harness K relay keeps the actuator in the circuit, but either one should work.

I have one of the original Harness K kits in my 2004 Z06 (before GM changed suppliers) and it has been working fine for a couple of years. I also removed the lockplate a couple of years ago before GM finally decided to install the same kit on the cars with manual transmissions as they had already done on the automatics.

Sir, Can you please point me to the source of your information? The CLB OR K Harness will work after recalls as long as you know what you're doing. Furthermore EFI Live cannot change this part of the flash memory unless a new breakthru has recently occured without my knowledge.

The recall on the MN6 does not remove the lockplate, only reprograms the computer. On the automatic the lockplate is removed. Obviously if the lockplate was removed it is not possible for the wheel to lock. Thus, his lockplate is still there. The latest service bul. now says to remove the lockplate on all US corvettes but "On Canadian and export vehicles equipped with a manual transmission, and export vehicles equipped with an automatic transmission, Dealers are to 1) reprogram the PCM, and 2) verify there is adequate lock plate clearance and, if necessary, replace the lock plate. After the service correction, the steering column will continue to lock when the key is removed." This was not always the case. Many Vette's in the U.S. have had their recall done and the lockplate remains. Once the recall has been done, the computer is still programed to turn the car off at >2mph if the error occurs. The CLB doesn't do anything to change this. My mistake that I said the CLB will not work at all. The car will still turn off at >2mph if there is an error between the CLB and the BCM. As far as EFI live, I'll ask the tuner about it. I watched the screen as he was addressing the issue but when I looked in the manual (breifly) I did not find it. Is it possible that there was a breakthru without your knowledge??? I hope so My best guess is that the tuner removed the 2mph shut off issue. Sorry for the confusion.

He didn't say his vette was from Canada. On the latest recall, 4006C, all lock plates, MN6 and autos, are removed and k harness installed. Therefore, the latest recall had not been performed on his car.
As far as a tuner removing the fuel shut off I've never heard that was possible.

"Many Vette's in the U.S. have had their recall done and the lockplate remains" (from my prior post) I didn't mean to imply that his car was from Canada. Just that the old recall was the "Canadian" version. Obviously his recall was of the older type since his column still locks. I'll let you know tomorrow about the fuel shut off.

4006C (the most current recall) removes the lock plate on MN6 cars.

Yes! anything is possible, however I will be very surprised if there is a workaround like this that I haven't heard about since I have worked with so many on this forum regarding the column lock issue including building my own. I think if it was that simple, we'd have a Corvette stampede to our nearest tuner to get the fuel cutoff fixed. Please do check with your tuner though and report back. We would love this to be true.
Cheers,
John
