The fuel cut-off is a different problem, and a maddening one at that. Basically GM introduced a problem that didn't exist before the recall, they did this by reprogramming the PCM to shut off fuel if the column locks up. This doesn't correct the column locking problem, it just immobilizes the car. Anyways, removing the K harness or installing a CLB will have no effect on the fuel cut-off, the code needs be removed from your computer by a tuner.

Just got off the phone with my tuner. The deal is this. Since installing the CLB the odds of something happening just went way through the roof.
Here is the catch with the fuel cutoff code. A tuner can disable it. But, and this is a big one for me. It also disables the rev limiter. So on track you accidentally bump up against the rev limiter. Well the fuel cutoff is not going to happen now. Big chance of engine go boom. It also means that if the car was attempted to be broken into / stolen etc that the VATS system will also not be able to do a fuel cutoff. All the circuits are sending the right signal. The computer will just ignore it. So if those other issues are not a concern to you then it is doable. I'd be really leery about not having a rev limiter in car that begs you to hit it

Doesn't the fuel cut off happen if the car senses a problem with the column lock, like if the motor fails or jams? Wouldn't the CLB kit effectively eliminate that from ever happening?

vms4ever, that's interesting info that you got from your tuner, is he absolutely certain about that, and can anyone else on this board confirm that this is the case? The only reason I question it is that from what I've read the shut-off code wasn't tied to the column lock prior to the first recall. I appreciate your post. I know this issue has been beaten to death but I for one am glad to be learning as much as possible about it.

Please help me understand this a little better. I picked up the car yesterday and all is well. Here's what they did:
Removed the "new" K harness.
replaced the key switch.
from the old recall, the locking plate has been removed.
Car runs fine with no errors being displayed.
So with this, am I still in need of an aftermarket CLB? I'm so confused !

Petsur, You said they removed the new K-harness? I dont know why they would replace the key switch? Unless they actually replaced the locking actuator removed the k-harness and plugged it back in stock. If this is what they actually did then yes you should be able to install the CLB and that would take your actuator out of the picture. With the CLB it disables that so it cant go in and out......

The letters are all in the thread below, including 04006B and 04006C.

Btw, I showed the 04006C letter to a local dealer and he said it didn't matter since my car had a previous CL recall done. I'd have to pay out of my pocket. Since I got the column to unlock and installed the CLB I didn't take it any further. If someone has to get their car fixed they will need to bring a printout of that letter.

Picked up the car and it's fixed, or at least the error message is gone. The car never left my sight once I left the dealership and hasn't left my garage or driveway since I've been home. The car was very dirty from the trip when I picked it up, and the day after I returned, I washed the car to discover a 8 inch long crack in the right front fender.
The dealer claims it didn't happen during the 3 days it was at his dealership, so I'm screwed. The dealer that cracked my fender is Steve Keetch Motors in Cortez Colorado. If you ever need any work done, make sure and avoid this dealer like the plague.

great info. i just found out this current info (June 26th 2007) becasue despite 3 times at my dealer the mother fing lock went again.
GM Service bulliten says that for MN6/MN12 all column locks will hae special coverage until February 2008. THat means for these cars until this date 100% coverage for the CL error including dealer covered free tow.
Part# change for the wiring harness for this year form the one you have posted 88952428 to:
new part # 89023816
Im about to go and "shock" it.. wish me luck... otherwise the dealer is omcing to tow my ****.

Installing CLB right now.
I am installing the CLB as we speak. I removed the knee bolster. I looked at the CL connector (next to the larger yellow connector) and noticed the wire colors were black, purple, green, and White. This would imply that a relay has been installed. Should I install the CLB anyway. Do I need to remove the relay in order to drive teh car. I don't want to damage anything. The CL has been operating just fine.
If I need to bypass between pins 30 and 87, any advise for what type of wire and cover I should use.
It's a 04 coupe MN6.
Update: Installed the column lock bypass and started it up. No trouble codes and the wheel turned freely from side to side.
But what about the issue of the white instead orange wire leading back to the BCM? The information in this thread indicates that there should be a relay. Is there more I need to do? WHat does this relay look like and how do I distinguish the wires I need to bypass. I am an engineer but not an electrician. Please give me a clean method to bypass the two necessary wire. If anything else needs to be done?
I appreciate everyones patience. I know this subject has been beaten to death. But the issue with the relay by the BCM and pins 30 and 87 has only been covered briefly. Is there a instruction out there somewhere. Thanks.

Steering column locked & would not reset
Wow, what a weekend. I made it to the church on time so everything worked out just fine but what a ride. After traveling 400 or so miles on Friday, I pulled into a hotel for the night to finish my journey the next day, Saturday morning. I was surprised when I read a message on my dash board "security steering column locked". I pulled the key out & waited ten seconds for a reset, but no reset occured. Chevy sent out an on call mechanic to dis-assemble steering wheel & lock so I could straghten out vehicles front wheels to be flat bedded to Chevy dealership. No Chevy service on Saturdays, call back on Monday morning. The rental car worked just fine. On Monday afternoon I was informed that my car was fixed. I was told by Chevy that the previous owner had the car serviced for the campaign / recall back in 2003. However, the steering wheel locking plate was still in place. Chevy now removed the plate & replaced a so called bad relay $ 411.00 later. Any suggestions on recouping the $411.00 for my 2000 hardtop coup's problem that was supposed to be fixed in 2003? I'm just very fortunate that it did not lock up while driving.
Thanks

You got ripped off, Call GM corp. They should reimburse the 411.00 bucks. removing the steering lock plate is part of the latest recall,and GM knows about the harnesses with bad relays , thats why they have changed them. Good luck

So I was about to push my car into the Brazos River..... So I got a beer, cleared my head and started brainstorming.
I disconnected the K Harness and put the wires back to stock, I had tried that earlier but it hadn't worked. I then inspected ALL of the BCM fuses, which you can find on the inside lid of the fuel Box. If I remember correctly they are 9, 13, 23, 25. My number 9 was blown. If I plug my K harness in, the message comes back, so I decided to leave well enough alone. I can turn my wheels even with the car off, so I don't see the column locking up becoming a safety issue.
