Do you know of a way to bypass the fuel shut-off function? I just checked and I had the 04006 recalls done on mine but no matter what I do now I cannot drive the car because I get the "pull key and wait 10 seconds" message. No matter how long I wait before putting the key back in and restarting I can't drive it because the fuel shuts down. I hear the CLB doesn't even prevent the fuel shut-down function from not working. I've talked to some people who have the CLB and the recalls done but have still had this fuel shut down problem occur. I've talked to some who said they can just wait 10 seconds, insert the key and drive...... that doesn't work for me. Mine shuts down no matter how long I wait. Any suggestions?
Anybody else had this same problem?

Yes, I've done plenty of searching on here and know alot about the CLB and service column lock problems but did not see anything much about the ability to fix the fuel shutdown.

 

The CLB will NOT help you with the fuel shut-off issue. The fuel shut-off was part of the idiotic recall.

If the CLB had been put in and the recall not done then you would have no problems. There's almost no point in putting in the CLB after the fact because the fuel issue still screws you.

 

Thanks for the info.
So would the fuel-shut off still be fixed under the terms of the recall? I already had the recall done once in 04 but apparently the fuel shut down still has issues. I'm gonna call the dealer 1st thing Monday but I'm sure they won't want to fix any of it for free even if it is part of the recall. Is there a way to reset the fuel shut down problem I'm having now?

 

My experience with this problem: a dirty or worn or faulty key can cause it. Clean the chip on the key with alcohol, however; once you get the dreaded "Service Column Lock" message, you'll need to disconnect the battery for about 25 minutes to allow the computer to reset before attempting to start with the cleaned or new key. Hope this helps.

 

I just recenly got me vette, is there a way for me to figure out if the recall has been done, and to find out if a CLB has been installed?

Thanks.

 

The fuel shut off can be disabled using Hp Tuners.

Autobot, my car has a sticker on the drivers side front fender that indicates the recall was done. There wqs a post in the last week that showed under the dash wiring for the CLB to see if it was done before.

 

I tried the alcohol tip on both sets of my keys... no luck.
I just unhooked the battery. I'll give it 30 mins and try it again.

 

What is the table that needs modified?

If you "undo" the factory recall, which can be done... you can use the CLB.

 

Check with your dealer and have them run a service history to see if the recall has been done. If you can turn your wheel with the key off, then either you have the CLB or the locking plate removed.

 

OK... unhooked battery... waited about an hour... hooked battery back up... tried both keys... same thing as before: "pull key and wait 10 seconds"... so I pull the key and wait then reinsert key... "service column lock" and the car will start but the fuel shutdown won't let me drive it.

What choices do I have?
1) tow it into the dealer and they will most likely charge me to fix it?
2) buy an HP tuner and try to figure out how to bypass the fuel shutdown functionality?
3) any other suggestions?????

 

The CLB will keep the fuel from being shutoff as long as the relay is working. Same with the GM version, the Harness K.
If you had the last recall, the lockplate has been removed so the column cannot lock, but you need a working relay (or actuator) in the system to satisfy the BCM so it does not cut the fuel.

As a way to make the car driveable until you can bypass the system, try reconnecting the column lock actuator. If you had a working actuator before the recall, you should be able to reconnect it and drive the car without the fuel being cut off.

 

I am getting so confused on this issue. I have a 04 M6. Never had a column lock yet. Did have the recall done which I verified with the dealer as reprogramming the computer only. My actuator still buzzes and then locks steering at shut off. But, I did order the CLB from Corvettes of Houston last week. Can I install this with no issues being that my actuator is working still without a fuel shut off problem arising? I asked Corvettes of Houston, and they said I shoud be fine. Any feedback for me guys?

This column lock hell is making me crazy guys. I keep posting, answering emails and phone calls and the problems just keep coming.

Once the earlier recalls were done, you have the fuel cutoff problem. You've just traded off one tow bill for another. In one case your column lock failed to unlock and you can't steer the car and in the other case your column lock failed and your fuel is now cut off. One post said had you installed a CLB and never had the recall done you'd be in great shape. I agree with this.

Many have had one or more recalls done and now they're on the path to column lock hell. Many purchased used vettes and are totally unaware of any issues...they must read and learn.

So starting from here and not knowing exactly what's been done to your car, what should you do?
1. Call the dealer and find out what recalls have been done to your car.
2. Remove the knee bolster under the steering column and inspect your wiring harnesses. The K Harness relay is located on the left side of the steering column. It plugs into a 4-wire connector(*) on the right side of the steering column attached to the horizontal metal bar under your column. NOTE: if you've had the additional relay mod installed, this connector will have white, purple, green, black; if it's stock, it will be orange, purple, green black. The K-Harness also splits off and connects to the column lock motor inside your steering column (orange, purple, green, black). If your column lock motor connects directly into the connector(*), you have not had any mods except possibly for PCM re-programing.
If you've had the recall mods and now you're getting the pull and service message, your fuel is probably being cut off and you can't drive your car even if you column is not locked. You can sometimes save yourself a tow bill by connecting the column lock motor directly into the wiring harness under your dash and thereby removing the K Harness from the circuit. This assumes your column lock motor is still good.

In the end, there is only one solution....install the CLB.

I am interested in finding out more about the fuel cutoff removal using HPTuner. Can anyone verify that this is fact and what parameter needs to be changed?

Cardinal Rules for Column Lock Hell:
1. DO NOT take it to the dealer
2. Be proactive and get a CLB installed.
3. Ask for help if you need assistance. There are many forum members on this forum that can help. I have a documentation package with photos that many will find helpful.
Best of luck to everyone.

I got my car out of the lock sequence by charging the battery. One thing I learned is if the electrical system, (battery), is low it won't unlock all the security features on the vette. I put it on a charger for a couple of hours and it started without issues Even if your battery started your car, it may be low enough to cause issue. I accidentally left my radar detector on for a few days and this ran down the battery which aggravated the column lock. Take some time and read the column lock posts at the top of this forum. Depending on wether you have a m6 or an a4 the fixes and issues are different. The column lock bypass is not a perfect fix either. There are posts about dependability and bcm problems from them. Personally if I had a mn6 I'd use the clb fix. If I had a a4 I'd do the recall. Hope this helps.....

 

Just send your tune file to support@hptuners.com, and they will disable the column lock fuel shut off for you. This table will be added to the editor in a future version.

Thanks guys,

My A4 apparently has the recall done. I actually bought a CLB, but have not installed it because I didn't want to goof up the recall. I'm keeping this on file for if (probably when) it gives trouble.

Thanks,
