Well, today it happened to me . :down: 1999 FRC

Weekend driver. Took the car out yesterday, all systems go.
No unusual events leading up to parking it last night. Got in today to take a little spin, fired it up and saw the "Pull key wait 10 seconds" message. I did that, fired it up and "Service column lock" popped up.

Codes are all designated history:

B1001 Option Configuration Error
U1096 Loss of Communications with IPC
U1016 Loss of Communications with PCM
U1064 Loss of Communications with BCM
U1255 Serial Data Line Malfunction (this one scares me)

I tried clearing the codes, disconnecting the battery and re-trying, no dice.

Also tried the violent steering wheel shake while turning the key, again, no dice.

I can hear an electronic type whine from within the steering wheel while turning against the stops and can also feel a distinctive click from within the wheel upon turning the key on / off.

New 7 year / 120 RC Delco battery (3 months) that sits on the CTEK when the car is parked.

When I bought the car I had the local dealer pull the history. He told me the column recall had been performed.

Here's the dealer report:





I can have the car towed to a local dealer that has a certified Corvette technician if need be. What scares me is my custom supercharger tune, I've read the PCM may have to be re-flashed... I hope not.

Have you looked at the CL sticky thread? Anything that can be or should be said about the matter is in that thread.

Yes, although distressed about the car I read it. But, there is so much information there I'll have to relax and re-read it.

I was able to free up by the "violent" method a few times until I decided to not press my luck and just parked it until I got the by-pass.

OK, I've been reading about this all evening. In The sticky bypass thread it states:

Q: Is there any solution for this problem?
A: Yes; have the recall done if you have an A4 car or install a Column Lock Bypass (CLB) on MN6 & MN12 cars BEFORE the problem occurs. Once it fails, you may not be able to fix it without GM repair.

At this point, I can't shake it loose, so the CLB should not be attempted. But, if I can get it free the CLB should work. Is that accurate ?

I've read where people were locked up and the CLB worked which goes against what the sticky says. My brain is beginning to burn.

Keep in mind that anyone can claim anything on the Internet. Thus, what you may have read in the past is probably false. That sticky, including the videos by C4C5Specialist is the real deal. You can fill out your will to it.

I know that it is a lot of information but it makes for a great read on the toilet. You're butt checks may be a little numb after going completely through it but your answer lies within that thread.

Thanks AJ...I'm going to order a CLB tomorrow and give it a good shaking next weekend. If I get it to free up at least I'll have it in my hand to install. If not...well, I don't even want to think about it.

It takes some serious racking of the steering wheel against the bump stops to get it to free itself. I know Patrick had to do it to his Vette recently. See if you can contact him. He may have some pointers.

If the columm lock re-call was done as least it shouldn't cost you any money right?

Realize that doesn't account for the custom tune you have...

Sorry bro. Hope this works out for you.

Thanks for the replies. I got the CLB ordered today, hopefully I'll have it by the weekend and have some success. I spoke to the tuner today, worst case, have the car dealer repaired and then ship the PCM to have my tune reflashed. All will be fine, alot of other worse things could happen.

Yea, you could have given a ride to a fat broad and she's still wedged into the passenger's seat with your wife standing there asking questions.

Sorry, that was my nightmare. :smack

If I was to take a wild guess, I'd say he accidentally took out the turn signal or cruise control stalk.
