Try removing the floor cover in the passenger footwell. the box on the right is the fuse panel. Pull fuse 25 and wait for 15 sec. and re-insert. This should reset your BCM. The fuses are numbered. A fuse map is located on the inside of the fuse panel cover. This will not affect your tune.

I was totally peeved last night at Lowes. Not because of the store but at GM's engineers and/or the dealership installers. I was stuck in the parking lot for 4 hours. During that time I was trying to start the car 70-100 times without the DIC saying Service Column lock. Attempting to drive it will cause the engine to shut off over 2.5 mph.

Before when I got that message, I just shake the locked steering wheel real hard when turning the key. That usually unlocked it and allowed the car to move. However, this time, since the actual piece that lock was removed from the last recall, there was nothing locked to begin with. From reading the sticky, the BCM is confused, it thinks it locked and is awaiting for reply/return to confirm it's been unlocked. There is where I was totally F__Ked. For 3.5 hours, I removed fuse 23, 22, 12, 10. Bought a $10 wrench to remove the battery cable. Shook the wheel hard. Banged the column loudly with my fist. Let it time out for 15 min. Hoping it will fix itself. Nope, no change.

Then I got desperate, I bought a torx wrench set from Lowes and began to operate. My intention was to disconnect and re-connect the column lock relay. That was harder than expected. I could not locate the disconnect. On to plan 2, locate the pin that's still moving. Found the plastic 1/4" diameter pin. It was engaged or locked, but no plate to actually lock the wheel (removed by recall). So while I was turning the key, I pressed the pin down. It WORKED!

What a nightmare. Wasted 4 hours in the parking lot trying to overcome this design/engineering flaw that GM supposedly fixed. I was very upset to say the least.

 

Wowie....you were pretty desperate and very creative. This is the first time I've heard someone push the pin back in. It's probably the K Harness relay that crapped out on you. You could have unplugged the K Harness and plugged the column lock motor back in without the K Harness in the circuit. 9 times out of 10 this will work to get you going unless of course your motor is bad too. Glad you got it going again.

Good info for me too. I am gonna try to get mine working this weekend (still in storage, put it away "just as" the fuel shutoff/lock kicked in).
Saleen, do u have any pix by chance of the pin? I'll do the harness thing first but thought I'd ask so I've got all my choices in line for Saturday.

Hey John, thanks for the advice. I can't send you brownies to CA but at least I can thank you on behalf of all of us.

 

Always glad to help.

Mine is doing the same thing post recall. 2000 A4 and I get the dreaded "pull key, wait 10 seconds" and then the "service column lock" but when I try to drive it the fuel shuts down. Tried the fuses, disconnecting battery, alcohol on both keys, etc but nothing has worked... fuel still shuts down. I've spent the last day researching this and talking to forum members and it looks like the choice I have is to try and pull the K-harness myself or since it's the fuel shut-off that's the problem I need to just tow it into the dealer for them to repair (again ). I assume they will reinstall another K-harness and flash the cpu. Is this correct?

 

Save the tow bill and do it yourself. It's really not that difficult. Email me at cscokd@gmail.com for help.

 

I have 1997 C5, the steering wheel works 100% with or without the key attached and the Check Colum lock system appears on the dash...

About 7 years ago, the car was stoled and I dont know if the thief broke this feature or what, but, the car works, dont stop the run or lock the steering wheel..

The question is: How may I clear that message? or most important, How can I be sure that the car will works always if are showing the message?

 

It sounds like the BCM is seeing a UNLOCK status signal but not a LOCK signal when the car is off, so it's reporting the message but not disabling the car. Your note is cryptic and not clear if this message just started or has been that way for a while. You can pull the BCM fuse that clears the memory flag used to generate this message (I think it's fuse 28 but be sure to search as the correct one is in here. If the message comes back then the feedback circuit is still seeing a UNLOCK condition which is fine - it won't disable the car.

But the ultimate solution depends on what the car has (CLB? Dealer TSB? Harness K? Disconnected CL?).

 

I really dont know.

The Last Owner told me today, about 2 o 3 years, the cars stop working and a guy who is a specialist in automotive electronic, made some conections so the car works again, but, the check column lock sign is still showing in the dash.

Right know, the car doesnt have the column lock, or at least the hard part that lock the steering wheel.

 

Is there a way that this thread can get broken down by what people have had done to there cars, ie one where they have nothing done, one where they have the recalls done and one where they have a CLB installed?

Anyways, on to my question, I have an 03Z with RC 04006 being completed. Is this the one with the bad relay, and if so what is the problem with it. Wouldn't it be easier to just replace the relay with a more reliable one if that is the only problem with this solution?

The other thing is if I were to have a problem with this recall completed, would I experience the fuel cutoff and if this is the case can I get rid of this feature with a tech2 (I have access at work to one)?

Thanks.

 

Seems barbaric but when I was working on these column lock errors when they first started being a problem I would remove the lock assembly. Energize the lock motor on the bench so that the lock pin would fully extend. I would cut the pin off flush with a cut off tool. I never had one come back. That was before the recalls.

 

I've had my 98 since 1999. Mine went back (on a flat bed) 6 times for all the recalls. I was told toward the end that there was NO reflash for the fuel thing. Bottom line here is what fixed mine and I tried everything.
My column has the locking mech removed.
CLB from Corvettes of Houston
Haven't had a problem since and thats over a year ago. You can go back and look at my threads and see all I went thru. I truly believe:
REMOVE LOCKING PLATE AND INSTALL THE CLB.

column can't lock and fuel keeps flowing
jddani@aol.com as I have quit following this website.
And yes, I got one of the GM complaint case numbers and all that but it's a crock until lawyers get involved. Until they do, you will have to fix it yourself.

 

I had the recall done and just installed a CLB, Ive had the "Pull Key....." message twice In two weeks. Not a big deal to pull the fuses but Im wondering if this is gonna go on forever. Its kinda embarrassing starting the car, then having to turn it off, pull the fuses, wait a min. and trying again.

 

remove and bypass the secondary relay in the passenger footwell if you had one installed during a recent recall.

 

No idea how to do that off to the search function. hope i can find it

 

email me at cscokd@gmail.com and I'll send you instructions.

After reading through all these posts, here's my plan. Does it sound OK?

The car is an 02 6 speed coupe that I've owned for a week. I've had no problems with the column lock. When I shut it off, I hear a "BZZZZT" and the wheel DOES lock. Only H codes reside in the DIC.

The paperwork shows that the recall was done, but it only references 04006, it doesn't say whether A, B or C versions were done. So I don't know if it was just reprogrammed or whether it has the K harness. From this sticky, I assume it was just reprogrammed.

I have orange, purple black and green wires coming down from the steering wheel on the left side, pretty much parallel with the column. They plug into a black connector on the metal bar under the knee bolster. On the other side of this connector is white, black, purple and green wires which disappear behind the dash.

I do not know if I have the K harness, I don't know if I'd recognize it or not.

I've ordered the CLB from C of H and plan on installing it.

Does my approach sound correct/reasonable? Did I forget something? Thank you very much in advance.

 

You just described my 03 MN6 and it's recalls to a tee. I just received the CLB from C of H this week and kinda waiting a few days before installed to finally decide if installing it has the chance of creating more problems than it solves. I'd like to hear the responses.

 

Anyone? Thank you!!
