PS I WILL UPDATE YOPU LATER


PLEASE CLARIFY:

RECALL 1 + REMOVAL OF LOCKING PLATE ??
RECALL 2 = K HARNESS INSTILLATION ??

And I guess we can check with GM if we supply the VIN # as to what was done ( if the dealer actually did what they claimed) to our vehicles ????

Visually and clinically we should be able to diagnose these cars.

RIGHT OR WROPNG ???

THANKS again

There needs to be a answer as many are plagued with a problem that the right information should be able to answer.

Thanks again and again
Mike

This will help with the HVAC drain.... not sure about protecting the BCM from moisture.

There are at least five ( count them for your self) variations of the "fix" that GM has attempted to correct the column locking problems in the C5.

Starting in early 99 the had a Customer Satisfaction Program where they made changes and replaced parts in the cars of customers who complained about issues with the column locking functions. This was the forerunner of the NHTSA forced "recall". It was referred to as CSP 001044. It was GM's attempt to keep NHTSA out of the problem.

In Feb. 04 the NHTSA forced recall began. It was termed 04006 by GM. It was such a poor attempt at fixing the problem that by Aug. 04 they came out with an "improved" version termed 04006A.

This was a total flop and in Nov of 04 they came out with another iteration termed 04006B. This did better and lasted until Jan 06 when they came out with the next and to the best of my knowledge last iteration and it is termed 04006C.

The 04006C iteration is the one where GM authorized the removal of the lock ring on cars built for sale in the US (although some dealers were apparently removing the lock ring on their own earlier than Jan 04.)

Here is a link to the actual GM paperwork sent to dealers for 04006C.

http://corvetteforum.net/c5/kenficht...olumn_lock.pdf

I would love to get my hands on the actual text of the earlier recall variations but at GM's directive each subsequent iteration instructed that the prior version documentation be destroyed. ( you wouldn't want a tech to be installing an outdated fix would you!!!)

The fuel shutoff came with the first actual "recall" (04006). This was GM's CYA in the event someone had the column lock up but still tried to drive the car and got themselves into an accident. Sure fire way to prevent a lawsuit. It was implemented by a reflash of the PCM that set the fuel shutoff speed at 2MPH in the event that the BCM "thought" the column was locked. Side note, EFI Live and HP Tuner software can set the fuel shutoff speed to a larger number. The GM Tech II and all other similar tools cannot.

What makes these column lock problems so difficult to resolve is that many cars had more than one of the variations applied to it and the fact that some dealerships were not implementing the fix as directed by the GM documentation. Add to that the crappy relays and wire harness that GM was providing and the complexity of the whole column lock implementation as GM designed it. It is a well known fact that the GM solution IS going to fail sooner or later.

The CLB is the best solution as yet available to keep owners from getting stranded. Two different things can strand you. 1) The column can actually lock up if the lock ring has not been removed. 2) The BCM may get into a confused state and think the column is locked when it is not and then signal the PCM to implement the 2mph fuel shutoff.

Installing a CLB however, can be tricky because you need to disconnect the GM solution(s). This is because the CLB wants to be the sole communicator with the BCM to "fool" it with respect to the status of the column being locked or not. If there are remanents of the GM solutions in place, the CLB cannot reliably control the signals being sent to the BCM. The tricky part is determining what GM did to a specific car so that it can be disconnected or bypassed.

By the book, GM only had to do 04006. They met the requirements of NHTSA with it. In reality they came out with the other variations because customers were complaining that the problem either was not corrected by 04006 or had come back (in the form of the fuel shutoff more often than not) because one of the components of the fix had failed. In some instances GM told customers they had to pay for a newer variartion if GM had already applied an earlier iteration. In many instances they did pick up the tab for a later variation being applied even though an earlier one had been applied at GM's expense. It depended on whether the dealer wanted to stand up to GM on behalf of the customer.

If iteration 04006B was done to your car then the GM Service History would show that you had no outstanding recalls. However, since the removal of the lock ring was directed only in 04006C, your column would likely still lock.

Hope this makes sense to you.

Here's the text for 04006C that all GM dealers received.

http://corvetteforum.net/c5/kenficht...olumn_lock.pdf

Read for your self . The procedure to be followed for all M6 and A4 cars delivered in the US was 1A (page 3 middle of the page) and it removed the lock ring. Recalls variations prior to 04006C ( ie 04006B, 04006A, 04006 and CSP 01044) were not authorized by GM to remove the lock ring.

Not sure of the procedure that they used to install the CLB but I would use the one in this link to try and install it again:

http://www.ls1howto.com/index.php?article=24


It has a step to follow if you get the error message. Use the step to try and clear it. If the error message continues then I would have to suspect the CLB is bad. (Or perhaps was damaged by the other bad components you had???)

If you decide to try the CLB again please post the results.

By the way did he mention where the "BCM RELAY" was located? Was it in the passenger footwell under the BCM?

I am still wondering if it could have been affected by the water intrusion during the heavy rainstorm I was caught in. The water (basically damp carpet) was located near the center console and the area around BCM appeared completely dry. Where can water get in that would affect the BCM, and BCM relay?

The Column Lock Relay is what you're referring to. It's the left most of the 3 relays right above the BCM and it sends the lock/unlock voltage upstream to the Column Lock Actuator (or Harness K/CLB if installed). It sounds like the CL Relay fried and may have damaged the BCM which is why both needed to be replaced.

Also remember that an earlier recall modified the wiring around the CL relay near the BCM. That modification was not compatible with the CLB which could be why your CLB was throwing the code.

Alrighty then. I have lost track of how many factory fixes there were for this problem. How would I know if my wiring has been modified? I have all the service records but there is no direct mention of this.

I guess I purchase a CLB that may be usless for me.

I'm just happy it's driving again

Heres what you need to do..

1. PCM needs to be flashed back to OEM (pre- GM recalls state) Call Corvettes of Westchester to do this

2. Ditch the k-harness

3. Install CLB from ThunderRacing. I never heard of the brand you mentioned. Does it say JMX on it? then keep it if it does because they are all the same.

CL issue is resolved for life.
