Just installed a new stereo system in the 2000 6 spd coupe. Went to drive the car and get the Pull Key Wait 10 seconds, then the Service Column Lock message appears. Steering wheel is not locked but fuel does shut off if you try to drive it.

Have CLB installed and no problems until now. I did use a wire from the PCM to give accessory power to the head unit. There is a plug with a black, yellow, and orange wire. In the C5 audio threads it is recommended to use this yellow wire for that purpose.

Fuse 23 is good and fuse 25 is good as mentioned to check in the FAQ's.

Battery is at full charge. Never heard of Alpine throwing this code.

I did disconnect the power wire from BCM and still get the code.

Suggestions?

 

Go back through every wire connection. It sounds to me like you screwed up somewhere along the line.

 

I have checked everything I can think of. Disconnected the head units power and still get the code. Uninstalled and then reinstalled the CLB and still get the code. Pulled all the recommended fuses both recommended by the CLB instructions and on the C5 FAQ and still get the code. Took the neg battery cable off for an hour and still get the code. There are really only two wires running the head unit. Power from the battery, acc from the BCM and that's it. Except a ground wire. No illumination wire.

Does taking out the stock radio affect the BCM?

I guess as long as I can keep it under 1 mph I should be fine.

 

While I dont know much about the C5 or column lock, there is a sticky here that might help you. It does not address aftermarket stereos and their relation to the CLB but it does address wires that are associated with it. Since I dont know anything about the C5 stereo wires, the first thing that comes to mind are the adapters used to connect aftermarket headunits with the factory harness. In my C6, there are a number of wires that would have to be spliced into (when not using an after market retrofit kit) that could easily be misinturpeted. That said, I would first look at the color wires and the locations for the CLB to determine if you might have mistakenly done something to effect them or spliced into them by mistake. It could also be a coincentance. There seems to be a service bulletin effecting some cars which could also be your root cause though I doubt it. If I were a betting man, I would guess that you cut or spliced the wrong wire.
From reading that sticky, it also looks as though there is a way to bypass the CLB though that would be my last resort.

Here is the sticky.

As I read all the threads before even starting the install there is no aftermarket harness to make an aftermarket head work with the stock bose wiring. I brought power direct from the battery to the head unit as specified in the Alpine instructions. ACC power was obtained at the BCM via a yellow wire that is mentioned in many threads as a good source for the ACC turn on power.

I even unhooked this to see if it made a difference and it did not. Other than those two wires and a ground to the seat bolt there is no other wire shared with any old wiring. All the speakers were newly wired and did not use any stock wiring. Amp is independent of everything with a power cable coming off the battery and a ground to the seat bolt.

Nothing is wired in with other stock wiring except the ACC turn on wire from the BCM. I unhooked it and no difference.

Grasping at straws here. I cannot find any threads that have an aftermarket stereo throwing any type of codes, especially the Service Column Lock. Just proud it happened at the shop and not on the road. Went to the local Vette guru and he claims the CLB should never allow that to happen.

May have to have the fuel shutoff tuned out and just hit reset everytime I drive the car although that is not the preferred outcome.

Someone has to have had this happen before.

 

Unless you accidentally yanked a wire or blew a fuse during your install, the radio wouldn't have anything to do with the service column lock issue.

I'd guess that the CLB somehow fried itself. In simple terms, all it does is disconnect the oem locking device and replace it with a resistor that fools the BCM into thinking the original device is working properly. You may have cooked your resistor. Try contacting the owner of this site, I believe he was one of the first to produce the CLB's, so he can probably tell you how to test it with a multimeter.

PLease let us know what you find
