Default Read lock thread. Still confused. Please help

Hello everyone!

As of July 31st I am officially a C5 owner (2000 Vert w/ a 6spd). As of August 21st I am having trouble with the column lock.

I read multiple threads on how and why it does this but I'm a little confused as my situation seems a tad different.

My steering wheel is totally free and able to be turned, but I just started getting the service column lock message. I can clear it but the car stalls as soon as I try to move it.

I presume the previous owner had the lock plate totally removed and the ECM reprogreammed, so what do I do now???

Is this able to be fixed with this CLB module I keep reading about or I am past this being off any help?


Any help you can give will be greatly appreciated!
Thank you all.
Ryan

I am no expert, but I did install the CLB in both my C5's.

Sounds like the locking mechanism has been removed/disabled, but the computer still thinks your column is locked.

I would check to see if you have a CLB installed. Do a search for an installation with photos to find exactly where to look, it is under the dash to the right of the steering column. If there is no CLB installed, order one ASAP and install it!

There are 3 versions of the dealer recall which did different things. It soulds like you have 4006C fitted which included the fuel shut off. It didn't fix the original issue just guarantee the car doesn't go anywhere if the column locks. A legal not an engineering fix I guess.

The CLB fools the car into thinking the column lock is working normally. Theres no 100% guarantee at this stage but the CLB should still solve the problem.

Others who have fitted it after GM have done their worst will chime in.

Ok Guys I need to make a decision fast. I am running out of ideas and it seems everyone has their own opinion on this.

Has anyone out there had the both recalls done and still had the SERVICE LOCK message with fuel cut off??????

Does this need to be towed to the dealership or not? I really DO NOT want to do that but I am thinking it may be necessary at this point.

I am willing to try the CLB module but from what I have read it seemsa too late at this point.

DO NOT tow your car to the dealership. The recall expired Feb 29/08 which means you will have to pay out of pocket to have it fixed, and we all know it just will screw up again in the future.

Purchase a CLB from either corvettes of houston or thunder racing and install it. If the fuel cutoff does not go away, you will need to either purchase HP tuners and remove the fuel cut, or find a tuner with the program and have them do it fo you.

I myself purchased a CLB from thunder racing and HP tuners and reprogrammed the fuel cut myself. It cost me around $550 but now the problem is fixed for good. Stupid F^$!*&g GM.

Bottom line is, if you get a relay in the circuit to fool the BCM into thinking the column is unlocked, the fuel should not be cut off.
Either the GM harness K relay (with a working relay) or the aftermarket version (CLB relay) should solve the problem.
The lockplate has been removed so at least you do not need to worry about the column physically locking. You just need a column lock actuator simulator to satisfy the BCM.
That is all the relay does. It sends a signal back to the BCM to make it think the actuator is in the unlocked position.
Chances are that you have a GM Harness K kit installed and the relay has failed, causing the fuel to be cut because the BCM thinks the column is locked.

This is pretty much my story. I ate at a Wendy's. When I came out, the car would start, but as soon as I starteed moving backwards it would shut off. I dicked with it for a few hours (not knowing much about the column lock issue) At some point, I noticed a harness with a relay on it connected to the column lock wiring(turns out is was the K harness). I removed the harness, plugged the two stock connectors back together and it has been perfectly fine ever since. Definitely try to find that K harness if it has it(sounds like it does) and see what happens when you remove it.

I can try to post pics tonight if you need them.

Ok gentleman,

I located and removed the "K" harness. Ironically it was before the last 2 members suggested doing so

Anyway, problem solved! WTF?????

So the relay they are installing during the recall is causing this stuff? I placed a phone call to the local Chevy dealer and he said "no way it was recall related, it must be something in the anti-theft system. He also claimed that "the whole point of the fuel system cut off is so a would be thief can't drive off with you car". -Whatever

My actuator motor in the steering wheel is working fine, I watched it zip in and out while I had it all apart. I went ahead and ordered a CLB module just to be safe in the future.

I guess I need not worry about programming out the fuel cut off. As long as the BCM doesn't get a haywire signal, it won't shut off the fuel pump. Sweet! Now I am ready for Carlisle. It's only a 20 minute drive for me.
Thanks to all of you concerned members out there, This board is every bit as cool and helpful as the Camaro Z28 board I've been a member of for years. -Ryan
