So, the notorious fuel-cut at 2mph happened to my friend while driving my 02 Z06 about a month ago, although he let it sit and everything worked after 10 minutes.

I took it to the dealer and asked about the recall (this was before I discovered Corvette Forum's experience), but they said it was already done on my car. So, I decided to do the CLB from Corvettes of Houston.

I went through their install instructions, but could not get the steering column lock to disengage with the 12V cigarette lighter adaptor. I checked the OEM cables/plugs and found the white wire, instead of the orange wire, indicating that they had done the recall.

I knew that they did the recall, but I wasn't sure which one, because I know that GM has issued several recall notices.

So, my questions are:
1) Is there a way to use my CLB from CoH to prevent the issue from coming back, even though I've had one of the recalls done?

2) If not, does it sound like I've had the most recent (Feb. 2006) recall done? With the key out, my steering wheel locks. If I get the new recall done, will it prevent problems?

 

1. Yes
2. No

Call Corvettes of Houston first.

I believe you can just unlock and pull the BCM fuse.

 

If both recalls were done, you need to have the pcm re-flashed to remove the useless programming by GM. Contact Corvettes of Weschester and ask for Chuck.

 

So, I did some detective work and found this:

Recall 04006 was done on December 17, 2004. This is the last recorded recall for the "electronic column lock" issue. So, they haven't done the most recent one.

I called CoH and they weren't able to give me any help. Basically, they said that given what I told them, the 12V adaptor should have unlocked the column lock...but it wasn't. Is my only option still Chuck at CoW? Should I let my dealer complete the most recent update to the recall?

 

no need for cow if the 2nd recall wasnt done. i had my clb installed even with the first recall done. although mine didnt come with a 12v cig adapter cord. i was instructed to pull fuse 23 during installation. my clb kit came from thunder racing.

 

So, you just pulled fuse 23 and connected the new box in?

 

Here is what i found after a short search on the forum, it was posted by Chuck CoW.

Maybe it will come in handy.

 

Is this what Chuck at CoW does? Or are those the dealer actions?

 

This was info taken from the GM website, and are recommandations, Chuck can do any of this actions, including the computer reprogramming that would ensure you would not have this problem again.

 

Call me crazy, but I don't see what is so unique about what COW does to eliminate GM's reprogramming. I'm new to using HPtuners, but it seems that any HPtuner having tuner can just flash in a pre-recall OEM program that can be found in the bin repository. Or they can even take that Pre-recall OEM program and modify it for more power and flash it into your PCM. I have nothing against COW but it seems to me that they aren't really doing something unique here.

We are talking column lock here... Whatever he does, works, and the dealer is not doing, because people seem to have repeat problems with something that it should have been fixed in the first place.
Also, i have not seen anybody else offering this service, yes installing the cable (i can do that) but the neccesary computer repograming that goes with it, no. I am not saying he is the only one that can do it or unique (even if he is) but he is the one that offered this service and can do it corectly, witch makes all the difference.
Information never hurt anybody, uncalled for or unnecessary opinions/ bashig, does.

 

Hey Hammer.....

Here's the deal..... The colum lock logic is not in the PCM, it's in the BCM and you can not re-flash it with HP TUNERS. Also, you can not re-program the BCM....I can. Installing the CLB permanantly prevents the col lock from engaging....... Most importantly, now that the column is not physically locked (and you can ALWAYS steer the car)..the next obstacle is that if the CLB or the BCM and wiring farts...The BCM commands the Engine Control Computer to cut fuel at only 2 mph. Now, even though the col is not locked...YOU ARE STILL STUCK.

What I do, which is different, is tell the pcm that the car was not outfitted with the locking column option......SO, when the BCM sends the signal to the PCM to cut fuel, the command is ignored and the car continues to drive.....

You might possibly get the "service column lock" message if I don't reprogram your BCM, but....YOU WILL NEVER GET STUCK my way...I make it impossible to get stuck.

Call me if you need help,
Chuck CoW

 

I know you are talking about the Column Lock....

I wasn't bashing, just stating something that seemed obvious to me that nobody else seemed to pick up on. Why that bothers you...

ON EDIT: Chuck's explanation of how the change is actually in the BCM cleared up my misconception.

Thanks Chuck...I now have a better understanding.

Have you checked that your 12V cigarette lighter has power?

 

Yep, I tested it using the cigarette lighter...it works.

I've only had one recall done (not both), so the going wisdom is that I should be able to use the CLB from CoH. And yet, I couldn't unlock the column with the 12V adaptor.

Ikester mentioned pulling fuse 23 during his installation of a different (Thunder Racing) CLB kit. Can anyone post their instructions from Thunder Racing...or tell me what to do differently?
