I know this topic has been discussed at great length, I have been reading the sticky and related posts. I have a 99 MN6, the recall work has been done sometime last year. I am getting the "pull key..." and "service column lock" messages. It will start, the wheel is not locked, but dies when you start to move. I have pulled fuse #23 and waited 30 minutes, didn't help. Is there anything I can do to get the car to run, without having it towed back to the dealer that did the recall work?

 

The dealer recall is the reason you are having this problem now

 

After reading the sticky and related posts, I know you are right. They are the cause of the fuel shutoff. Is there anything I can do to get it running? The car is at my home, but the dealer is 20 miles away.

 

I think you are screwed. Try disconnecting the battery for 30 minutes and see if it resets.

 

I would also run a diagnostic and clear any codes. This might get you running to get to the dealer. Then for the love of Duntov get a CLB.

 

Sometimes trying another key or cleaning your key will work. Also a little gentle persuasion { beat the hell out of it with something that won't cause permanent damage} of the steering clolumn might free up the pin.
Question, when you turn on the key do you hear the motor running in the column? If so the car is attempting to retract the pin in the locking mechanism. If it runs, I believe that the column lock bypass will help you. I would order one ASAP regardless of whether you have the car towed to a dealer. What to expect if taken to a dealer is several scenereos. First they'll want to install a new locking mechanism, followed by a new cable and/or a new BSM. It'll be over $1000 by the time they wish you a happy trip home. The bottom line is they make a fix by shot gunning parts until something suddenly starts to work ok.
Most likely it's the cable to the column lock mechanism that has gone bad, the CLB kit replaces that by bypassing the Column lock mechanism and telling the BSM that all is OK.
Good luck.

 

Should have done a CLB.
Hope you get this fixed. But I think only the dealer can help you now. Good Luck.

 

Reread his post, it is not locked...the fuel is cutting off.

 

The BSM thinks it's locked. That's why I suggest the cable is most likely bad. The CLB should fix that as it uses it own cable and . If not, I'd do it anyway.

 

Ok...I guess your first paragraph about beating the hell out of the steering column to make the pin drop confused me.

 

I am confused. How does "run a diagnostic and clear any codes" repair anything? What does that do, but clear out the history?

 

I have the Corvettes Of Houston CLB installed, but I still occasionally get the "service column lock" followed by the fuel shutoff when I try to drive away. When I turn the key I don't hear the CL motor activate and the wheel is not locked.
What's up with that?

 

I have a 99 MN6 also. The earlier recalls had been done when I bought the car. Late last year when the last recall came out I had the local dealer do it, which removed the lock plate ,installed a K harness (GM's version of a CLB) and a relay. Immediately I started to get pull key,wait 10 sec messages and then "Service column lock" with the fuel shut off issues you're getting. I called the dealer and they flatbedded the car back and replaced the lock motor and the harness /relay. 6 weeks later, same thing. This time based on advice from Chevrolet they removed the relay completely. End of problem so far. They covered the two flatbedding charges and all repairs bc I never had any issues until the recall was done.

See what your local dealer has to say, evidently there is a technical service bulletin that my dealer was not aware of that identified the relays they install as the problem. I called Chevrolet customer service to help get the solution in my case. They treated me very well.

 

GM is aware of a faulty K harness they were using in the recall, they have sinced replaced it I believe. Apparently not all dealerships keep up with current info from GM.

I have also heard of some problems associated with using the CLB AFTER the recall. It appears the best bet is to not have done any of the recalls and just used the CLB. Too bad the dealers won't put your programming back to stock after they messed it up with the recalls.

 

See answer in the tech section.
If you can hear the actuator cycle when you turn the key, then the lockplate has been removed and the relay in the harness has failed.
Try removing the panel below the steering column, removing the Harness K wiring harness, and reconnecting the actuator.
This should allow you to drive the car until you can replace the relay, provided the actuator is working.

If the actuator does not work, then you will need to replace the relay harness with a working one. You can either get the dealer to replace it under the recall with the GM version, or replace it yourself with an aftermarket version, the CLB, which leaves the actuator disconnected from the circuit. In either case, there must be a working relay in the circuit for the correct signal to be sent back to the BCM to keep the fuel from being cut off.

 

Where exact;y istherelay located?

 

The relay is locaated in the passenger side footwell fuse panel. I suspect you have a failed relay or wire going to it. Part of the 'C' version of the recall is to installa new relay of a different type than originally fitted to the car. It is possible either the relay has failed or one fo the wires has unplugged, or a joint has failed. If you send my your email, I will send you a PDF of the complete 40 page recall and associated service procedures. There are drawings and instructions on changing out the realy, as part of the whole process. There have been A and B vesions of the recall thqat predate the C version, and some dealers have ONL peforemd the earlier mandated work. Neither GM nor my local dealer who has my name and car data on file ever contacted me about the recall. I had to find out about it myself and have the dealer runa vehicle history, to find out the A and B version of the recall had been done, but not the C verson, that actually removes the lockplate from the column. I already extensively modified the column so I have no need of the now lockplate.

Please PM me with your email address, and I'll send you the PDF of the C version of the recall. It is very informative and not all GM-Chevy dealers are even aware of it. Several people I have sent the PDFs to have printed it out and brought it to the dealer after having been told it did not exist!

Hey, you know that nifty little device that retracts the column lock from the cigarette lighter plug (included in the CLB kit), I wonder if that would get him going, if he's not in a hurry, I could send him mine. Or perhaps just order a CLB from Corvettes of Houston, retract the CL, and install the module.

He says the column is not locked, just the speed limiter is engaged, because the BCM thinks the column is still locked. I would get into the area and shake the heck out of the cable going to the mechanism then try again. If the wheel is adjusted often the cable might be bad from being moved often. Just a thought. There are complete instructions with pictures on accessing to undre dash area here http://97vette.com/howto/columnlock/index.html

 

This is exactly correct. I had my done a month ago. 97 A4 . The first thing I was told is that GM got wise and figured out the reason for all the recall combacks was because of the faulty relay in the K harness. They have replaced that with a better relay and the comebacks have reduced almost completely. Mine had not had any of the previous recalls done to it. Therefore there was no reprogramming done to mine. They just removed the column lock and put in the relay. I watched. So far Ive drove it almost a 1000 miles with know problems.
