THIS BULLETIN CANCELS AND REPLACES BULLETIN 04006B, ISSUED NOVEMBER 2004.

THE SERVICE PROCEDURE FOR U.S. VEHICLES EQUIPPED WITH A MANUAL TRANSMISSION HAS BEEN REVISED. PLEASE REVIEW THIS NEW INFORMATION IMMEDIATELY.

ALL COPIES OF BULLETIN 04006B SHOULD BE DESTROYED.

Condition

General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 1997-2004 model year Chevrolet Corvette vehicles. When you remove the ignition key, the electronic column lock (ECL) system prevents turning of the steering wheel. When the vehicle is started, it unlocks the steering. Two conditions can prevent steering while the vehicle is moving:

The vehicle is designed so that if the column fails to unlock when the vehicle is started, the fuel supply will be shut off if the driver tries to move the vehicle. If voltage at the powertrain control module is low or interrupted, however, the fuel shut off may not occur and the vehicle can be accelerated while the steering is locked.
During quick cranks, the ECL lock pin may not withdraw fully and, in vehicles where there is abnormally low clearance to the lock plate, there may be contact between the pin and lock plate. This can cause a noise or ratcheting when the steering wheel is turned, or if there is insufficient clearance, the steering wheel cannot be turned.
If one of these conditions occurs, a crash could occur without warning.

Correction

Dealers are to remove the column lock plate on U.S. and Canadian vehicles equipped with an automatic transmission and U.S. vehicles equipped with a manual transmission. After the service correction, the steering column will no longer lock when the key is removed.

On Canadian and export vehicles equipped with a manual transmission, and export vehicles equipped with an automatic transmission, dealers are to 1) reprogram the PCM, and 2) verify there is adequate lock plate clearance and, if necessary, replace the lock plate. After the service correction, the steering column will continue to lock when the key is removed.

Vehicles Involved

Involved are certain 1997-2004 model year Chevrolet Corvettes equipped with a manual transmission, 1997-2000 Chevrolet Corvette equipped with an automatic transmission, and 2001-2004 Chevrolet Corvette equipped with automatic transmission (European export only), built within these VIN breakpoints:

Dealer Recall Responsibility -- For US and IPC (US States, Territories and Possessions

The US National Traffic and Motor Vehicle Safety Act provides that each vehicle which is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time.

Dealer Recall Responsibility -- All

All unsold new vehicles in dealers' possession and subject to this recall MUST be held and inspected/repaired per the service procedure of this recall bulletin BEFORE customers take possession of these vehicles.

Arrangements are to be made to make the required correction according to the instructions contained in this bulletin.

November 2004
Dear General Motors Customer:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. Federal regulation requires that any vehicle lessor receiving this recall notice must forward a copy of this notice to the lessee within ten days.

Reason For This Recall

General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 1997-2004 model year Chevrolet Corvette vehicles. When you remove the ignition key, the electronic column lock (ECL) system prevents turning of the steering wheel. When the vehicle is started, it unlocks the steering system. Two conditions can prevent steering while the vehicle is moving.

Your vehicle is designed so that if the column fails to unlock when you start your vehicle, the fuel supply will be shut off it you try to move your vehicle. If voltage at the powertrain control module (PCM) is low or interrupted, however, the fuel shut off may not occur and the vehicle can be accelerated while the steering is locked.
During quick cranks, the ECL lock pin may not withdraw fully and, in vehicles where there is abnormally low clearance to the lock plate, there may be contact between the pin and lock plate. This can cause a noise or ratcheting when the steering wheel is turned or, if there is insufficient clearance, the steering wheel cannot be turned.
If one of these conditions occurs, a crash could occur without warning.

What Will Be Done

Your GM dealer will remove the column lock on U.S. and Canadian vehicles equipped with an automatic transmission. After this service correction, the steering column will no longer lock when the key is removed.

On vehicles equipped with a manual transmission, and export vehicles equipped with an automatic transmission, your dealer will 1) reprogram the PCM and, 2) verify that there is adequate lock plate clearance and, if necessary, replace the lock plate. After this service correction, the steering column will continue to lock when the key is removed.

This service correction will be performed for you at no charge .

Until your Corvette is repaired, you can easily verify that the column is unlocked by turning the steering wheel a full turn before shifting into gear. If you hear a ratcheting noise while turning the steering wheel or experience column lock after starting the engine, contact your dealer to arrange for repair.

How Long Will The Repair Take?

This service correction will take approximately 20 minutes to 1 hour and 40 minutes, depending on the type of transmission you have in your vehicle. However, due to service scheduling requirements, your dealer may need your vehicle for a longer period of time.

Contacting Your Dealer

To limit any possible inconvenience, we recommend that you contact your GM dealer as soon as possible to schedule an appointment for this repair. By scheduling an appointment, your dealer can ensure that the necessary parts will be available on your scheduled appointment date.

Should your dealer be unable to schedule a service date within a reasonable time, you should contact the appropriate Customer Assistance Center between the hours of 8:00 AM and 11:00 PM, EST, Monday through Friday. They can be reached at the number listed below:

why would this need to be a sticky? We have a column lock sticky already

LS1Love

And Yes...this is the GM notice in its entirety

foremaw

I thought I already read something once on the forums about the column lock bypass issue..........but I may have been mistaken. I'll do a search and see if I can find it.

briann510

And you're gonna trust a GM person to do all that on your car and expect it to actually fix the problem?

jdmvette

a blast from the past...

tsts

Was there something new here, from what I read it seems this has been covered before - but I only read the first few pages and the part that applies to my vehicle?

Does the poster of the thread have any comment to help us distinguish this information from what already exist in the two stickies information at the top, is any of this information different?

BlackZ06

The poster of the Bulletin lists his occupation as "GM Legal Staff"

Either he's helping GM with a little CYA, or possibly he's unaware of all the traffic and sticky's on this issue, and like any lawyer, shoots first and asks questions later

LS1Love

LS1love,

You say:

"Actually....I was trying to make light of a new Special Policy adjustment Gm just released also relating to the column lock. As well as list the revised version "C" of the recall."

Are you kidding ... NEW ... it's dated April of 2006 ...... and was posted back then in this sticky ...

http://forums.corvetteforum.com/show....php?t=1312929

about the time this Revision C notice came out. In fact scroll down on the first page and you'll see the first part of this document that you posted was already posted back in April of 2006. Starting a post asking to make a long document like this a "sticky" with ABSOLUTELY NO FURTHER EXPLANATION is gonna cause most of us to go as we have seen this beaten to death as a topic.

It's a sore subject with many of us, my car has been in TWICE for the recall. My first time I drove it in as a response to the recall notice. The second time I had to pay a tow company to flatbed the car to the dealer (This is because GM couldn't figure out how to do it right the FIRST time). The dealer had the nerve to tell me that the column lock CONTROLLER was bad and it wasn't COVERED !!

After a short, expletive filled, discussion with a GM rep from the zone office it was "agreed" that GM would cover the controller as part of the "recall".

So, as I say, this is one sore subject, and you're gonna want to be pretty thick skinned by posting ANYTHING to do with this recall UNLESS it is REALLY new information from GM.

Thanks for trying, your heart was in the right place ... just didn't quite work out in the execution ....

The Service Column Lock message appeared after my battery ran down. I've done research on the site and it appears my vehicle should be eligible for this recall. Contacted my local dealer with my VIN and they say they cannot find the recall? I have prited this thread and will be headed to the dealer.

Corvette_Ed

DO NOT take your car to the dealer to have this fixed. Please check the sticky thread at the top of this forum for the proper way to handle this issue.

I would also suggest you go ahead and purchase an LMC5 from Compliance Parts. The LMC5 is what I used to fix the problem in my 2000 coupe. Here is the Website address for the LMC5:
