2000 Auto should not have fuel cutoff in column lock condition

A: Yes. This is the original design.

A Your DIC will display "Service Steering Column Lock" error message; your steering wheel will not be locked; if you own a 1997-2000 C5 that has not had the recall implemented; you should be able to drive your car normally. You must reset your DIC each time you start your car if you are annoyed with the error message. IF you have a newer C5 (2001-2004) OR you've had the recall implemented, you will NOT be able to drive your car because the fuel will be shut off at speeds above 2 mph.

A IF you have a MN6/M12 car, the recall does NOT disable your column lock motor. It simply re-programs your PCM to guarantee your fuel is shut off at speeds above 2 mph so you cannot drive your car with the steering column locked.

Does anyone agree with my thinking here, or is the Cscokd posting on the first page of this thread inaccurate?

The BCM has always an continues to receive lock state signals (from the CL lock feedback switch, the Harness K, or CLB) and if it is not happy with the state it sees it will disable fuel - PERIOD.
If you don't believe me, access the Corvette Service Manual section on this - it clearly outlines the original design of the BCM/PCM interaction.

What would you do!
I have my vehicle in at a GM Dealer - good vette dealer - doing some work for me.
Question is I had the first Recall done 04006B on the column lock two years ago and have not had one problem since then.
Since their is a updated recall - 04006C - would you have them conduct that one as well/ with my luck I will start having problems.
I guess they remove the plate on this one.
Advice Please

I had the column lock last week and was flatbedded to the local dealer. None of the tricks found here would free it up. I made sure to tell him about the new recall (4006C) and he said he would research it.
When I picked up the car I had a $450 bill and the recall wasn't done. He claimed that I had a short in the column lock wire that had to be fixed. He also replaced relay part #12193601. He did research the recall and said mine didn't need it because 4006B had been done. I argued and he said he couldn't do a recall unless the vin showed it needed it in the GM computer system.
I went as high as they would let me through the GM phone numbers and they are holding firm to the car not needing 4006C if the previous one has been done.
I'm afraid those of us with manual transmissions may have problems getting this done.

I see you have a '99 MN6. Recall 4006C is the first recall to disable the column lock on MN6s. The recall notice lists the VIN breakpoints: X5100001 through X5133283 for the 99s - I assume your's is within this range.
For the record, I have never had GM touch my CL because I installed the CLB when I first bought my car. You should still look at getting the CLB installed either way you go.

GM doesnt have to do the 4006C recall UNLESS you have a message in the DIC or have to have your car towed in with a locked column. My car hadthe 4006 recall done in 2004 and I just talked to a 3rd dealer this morning about my car and they WILL NOT DO THE 4006C ON IT PERIOD. End of story they said.

If other dealers are doing the recall a second time how are they getting it through GM?

Really quick, i bought the CLB from COH and had the 4006C recall done, which is the removal of the locking ring. Now can i just install the CLB or do I have to remove anything before hand? Thanks in advance.

Looks like tomorrow is going to be the third time on a flat bed! Have had every version of recall done on my '02 MN6 including taking the locking ring off. Just got the Service Column Lock message again and shut down. Tried pulling the #23 fuse to reset the BCM and it backed it up to the pull key and wait 10 seconds message and then it gave me the Service Column Lock message again. Unreal. Can't wait for the run around at the dealer again. Sure they will try and bill me for something on it!
Had already decided it was time to sell the vette. This just confirms it. They are awesome cars, but I have to drive mine everyday and can't deal with having to take it to the dealer every 3 months for the same B.S. problem.
