Steering column lock: with a twist: Please HELP! (LONG)
Lets just say "FUNFEST" Was not so FUN! LOL!
While there I got the dreaded Steering column lock.
I had the CLB on the car, no recall done to it.
It is a 2000 FRC, with heads, cam, headers fast 90, ect. so it has a tune in the puter.
Anyway, it is sitting 300 miles away at a GM dealer now.
They as of now have no clue. I told them about the CLB i had, and the flashed PCM. The rest they could see, and hear! LOL!
Before they even got it, I had checked the DIC for codes. It does not show anything related. So of course they are not getting anything either with there diagnostic stuff. .(just the one message that comes up saying service Steering column lock)
They think that it because of the PCM flash, witch is with HP Tuners. I cant see that that but that is there thought?
At first I tried the 2nd key, and it went away. Then it came back at random. I could turn the key on and off several times and get rid of it. Now it is just constant.
So PLEASE help me HELP GM get this fixed! LOL!
I will answer any questions, if it will help? As I, and them are puzzled.
Thanks for any help..

This is just a wild-assed guess, but if you have the CLB and you're getting the column lock message, perhaps the CLB has gone bad. It's whole job is to tell the computer the column is unlocked. I'd try replacing it.

have them unplug the clb and plug the actuator back in and see if that works. If so, I'd agree with Jim and get another clb. Rare but I've heard it does happen...........

Just went thru the same crap with my Bro's 99 FRC.
Took it to Tom Oates Chevy here in the PA area. They did the new recall which requires the removal of the locking plate from the steering column and reflash of PCM to stop fuel cut-off.
The fix is free until February 2008. Just have them do that and you will be fine. If you have a hand held tuner like a predator you can go down load your tune before they reflash your computer.
I would also have them check your battery, the biggest cause of column lock is a loss of power or low voltage.

Ok guys, they are going to do the recall on it and see if that fixes it before they go any further. But I don't think there is a flash for the 6 speeds?
My tune by the way is with HP Tuners and I have a saved copy. Although if there is a flash of the PCM with the recall, that will not do me any good, will it? As it would not have the fuel cut off adjustment in my flash.
P.S. No the wheel does not lock, at least it did not before GM got its hands on it? LOL!

Maybe one of your relays failed or your battery is going bad. Would have system load tested.

Your column lock, (i.e. the locking plate) is not locking your wheel which is the first sign of clumn lock.
The second is the fuel cut-off.
That's why I suggest that you may have had a component of the column lock kit go bad.

Well, they did the recall work.....
Took it for a drive, seemed OK......
Till...... they shut it off.. went back a little leater .....
And the same thing happened..
I still think it is the BCM or something along them lines?

1. I assume your battery is good. So check to make sure fuses 23 & 25 are good in passenger footwell
2. Check black wire to CLB is a good ground
3. Check to see 12V on purple wire to unlock and 12V on orange (white after GM mod) wire to lock.
4. Check green status line 12V when locked
5. There is a secondary relay mod GM put on MN6/M12 cars just above your BCM. That relay may have failed. If you have Orange, Purple, Green, Black wires where you plug in your CLB harness, then you do NOT have this mod. If you have White, Purple, Green, Black wires, you DO have this mod. Email me and I'll send you my tutorial. cscokd@gmail.com
6. If all the above checks good, then it's looking like your BCM is suspect.

Before it was taken to GM, I pulled the codes on the DIC.
It showed B0502/B0507, RH-LH DRL relay, and B2482 Backup Lamp relay. These are things I have had replaced in the past. Although they were showing as history and current?
And something I totally forgot till just now. On the interstate, on my way to FunFest, the traction control turned itself off. I could not get it back on with the button. It did go away after the car was turned off. This is when the messages first came back.

2-5. The CLB is no longer in the equation, as they just did the recall. Although that has not fixed it.

I had the same condition & Chevy just repaired it along with the help of GM techs on the phone ( Third times a charm). I received a very hefty bill from Chevy, I am now in conversation with GM regarding bill since they just paid for the dreaded service steering column lock @ 7 weeks ago. Hears the fix as it was told to Chevy mechanic from GM techline: steering column lock failure, no codes in BCM or PCM. REMOVE purple relay wire from sensor and C-3 A-6 connector,switch orange and white wires at relay. replace relay switch green wire and relearn sensor system wires required. This is how its written on my bill. Good luck
keep in touch.
