Default CLB didn't work.

Well I got my CLB today from Corvettes of Dallas. Went right out and installed the part as per instructions. Went to start the car....same problem, fuel cutoff. I called them up and spoke to one of the techs and he said to try it again this time take out the fuses again but wait 15 minutes, the instructions were wrong they say 1 minute. Well I did that and nothing. Called them back and the tech was eating lunch and said he never had one that didn't work, then he said it must be the BCM. So I said O.K. and figured I let him finish his lunch. I was very disappointed in them, they were basically no help at all. They didn't even offer to exchange mine to maybe see that the one they sent was bad. The just kept telling me they never sold a bad one.

So now I have spent $50 and still have this same problem. How do I solve it now. I really don't want to spend 600 for the HP tuners program.

It's a 99 convertible, The battery went low and that is when the problems started. The codes are all clear except for BO RFA 1096 H, RFA 1064 H AND RAF 1016 H. These must come up when I pull the fuses or disconnect the battery.

Was that the first time the CL failed? Did you get the "Pull key and wait 10 seconds" notice? (before you installed the CLB.)

Like I told you before, I got the same clb and it got rid of the fuel cutoff. Did you plug into the lighter to disengage the actuator?

I had the K harness in the car so it must have failed at one time before I bought the car.

Yes I got that message before I bought the CLB. That is why I bought it. Before that I was unaware of thes problem waiting to happen

Did you completely remove the old Harness K relay?
It is possible to connect the CLB to the end of the harness and not to the main wiring harness.

What fuse/fuses did you pull?? I ran into a similar problem with my install. The instructions say pull #25 and wait,,which also did not work for me. After studying the fuse cover I noticed there are 3 BCM fuses,,# 13,,23 AND 25!! I had also read somewhere #29 helped as well. I pulled those 4 fuses(for about 15 min.) and TA-DA it worked!! Might want to give that a try! Again #13,#23,#25,#29,,,,can't hurt,,might just work!!!

Q For MN6/M12 cars what can I do if this situation occurs?
A Go into your passenger footwell. Remove your BCM and locate the recall mod relay, remove it and add a jumper wire between the white wire (pin 30) and the orange wire (pin 87). Note that there are two orange wires, so make sure you get the right one!

there are definitely more fuses than just #25 that have to be pulled.

I think '99's in general must be a royal PITA for the CL. I have never got mine to work by pulling any of the standard recommended fuses. The only way I have ever got mine to work is as follows: (K-harness removed)

Disconnect the battery, look on the inside of the fuse cover (the one inside the car next to the BCM), write down every fuse that could in anyway affect/power the bcm. There will be a lot, maybe around 10, I don't remember for sure. Pull all of the ones you wrote down, make sure you know where to return the fuses with the proper amperage (it seems like all the ones I pulled were 10amp, but again not sure, the fuse cover should tell you anyhow). Now unplug the wiring harnesses from the BCM. If you have the relay that has been added because of prior CL recalls unplug that too. The relay should be literally "floating around" somewhere near the BCM (the dealer might have really half-assed mine), I think it has 5 wires 3 of which that are 1 purple and 2 orange. Then replace everything and reconnect the battery and see what happens.

The car is an automatic.

Pulled #13,#23,#25,#29. No change.

It's amizing how screwed up this car got because the battery went low.

Have you examined the wires inside the rubber accordian boot on the drivers side between the door and body?




What wiring would be in there to affect the fuel shut off. I have the door apart in order to remove the mirror for painting.

Friday morning still not working bump


I had left the battery unhooked all night. Went into car to move at 2 mph. When I started it I still got the alarm but it let me go over the 2 mph. I thought it had fixed itself. I shut it down and it started and worked again. But the 3rd time I tried it it went back to 2 mph.

Thats a good idea.

540 vette

Make sure that the K harness is removed and Hook the column lock connector/s all bak up in the stock configuration and see if you can hear the column lock motor function. When you turn the ignition ON, the column lock motor should retract the bolt. Then see is you still have the Fuel Shut Off.

Might be a dumb question, but did you check to insure the battery has a full charge?
And I didn't mean just running it and charging it with the alternator, use a battery charger and load test the battery.
If the battery is suspect replace it before wasting any time chasing something else.

Something no one has mentioned is that the CLB WILL NOT fix the problem after it has occured. From what I have always read, if your system locks you must go to the dealer to get it unlocked and than put in the CLB to prevent it from happening again. I am no expert, my battery went dead on my 02 and I had all these same problems, plus the doors would no longer unlock, and had to have it towed to the dealer to get everthing reset. Just my two cents, but that is what I have understood.

The column is not locked. The fuel shut off is the problem. And I did a search of the forum and many have solved it and seem to think it solves the problem.
The tech at Corvettes of Dallas said it would solve the problem that's why I spent 50 bucks on it. If that wasn't the case I would have saved the money and used it for a tuner to take it out.

All I am saying is when the problem happpened with mine i called Corvette of Houston and they told me that the CLB will not correct the problem, only prevent it from happening again in the future AFTER the column is unlocked OR the fuel shutoff is reset. It, the clb, will not repair or reset the system!Just telling you what they told me and what I have read on other threads. Take it for what it is worth, don't shoot the messenger.
