I’ve searched google and forums, but have had no luck with removing the message.
My car had an lmc5 installed when I got it and still had the message. I deleted the vats, installed the proper resistor in the ignition to delete the vats key, vats is deleted in tune also.
I thought maybe the lmc5 was bad so I ordered a new one and followed the instructions to the letter including the brown wire mod, but I still get the pull key message every time I turn the key to accessory.
I can turn it back off and when the message goes away I can turn the key back on and it doesn’t show the second time. Is there possibly an issue with the BCM as to why the lmc5 isn’t working?

You may have the factory installed version of the LMC5. Visually inspect the cable where the LMC5 connects and follow it upstream and see if there is another relay plugged in. My 2004 car had it and it took me a while to find under the dash. A friend with an older FRC also had one installed by GM but his was in the passenger footwell. Good Luck.

I’ll have to check into that for sure, it’s very annoying having to turn the key on then off then back on to drive without seeing it all the time.

So wait.....you purchased a new LMC5 and installed per the instructions, correct? If that is the case, you do not have a factory installed CLB! If the instructions were followed, you should have removed the Column Lock relay.

The column lock relay by the BCM was removed previously, I doubled checked to make sure it wasn't there when installing the new LMC5. I thought maybe they were talking about a different relay and was going to check to see if I found anything else in the loop that may need to be removed.

Ok, so based on what you are describing, the contacts in the ignition switch that tell the BCM a key is inserted may be an issue. The BCM monitors three things : 1) Key is inserted in ignition (provided by ignition switch plunger) and provides a ground to the column lock circuit 2) Monitors the column lock circuit (simulated by the CLB) for faults. 3) determines status and will take action i.e. tell PCM to disable fuel......PULL KEY - WAIT 10 SEC......etc.
You can mointor the resitance to ground at the BCM connector. Worth a look.

Ok, should the resistance at the bcm be what the resistor on the key should be? My key resistance is 1.124.
My car does this about every third start. However, during the winter when it's been on the battery tender, it will do it every time. So it seems to do it on a full charge as well. I sometimes wonder if I have a ground issue. My LCM5 was installed years ago, but this has only been a problem for the last year or so. Have you checked your ground points lately? Just a thought.
I had a situation several years ago where the ECBM and BCM kept throwing codes. I have a convertible, and can assume the previous owner had the top down in some rain, and or he didn't clean the drain utters ever, so some water got on the BCM. I tried for weeks to hunt down the issue, but in the end took it to a trusted mechanic who determined the BCM had ground issues with the ECM and the EBCM. He strung a new 12 gauge ground wire between the three and all of my issues were resolved. But now I am having a few vats and LCM5 issues again, so my plan is to check those grounds for corrosion and clean them if necessary. Apparently a poorly grounded BCM does some pretty screwy things to your car. Your schematic would have been very helpful to me when I was chasing this down myself all those years ago.
Ah, the pull key wait ten seconds message, what a mystery. My 97 still has a functional locking steering wheel, and no LMC5. No message from late spring to early fall, and then mysteriously that message will start appearing, I do what the message says and no problem, only happens the first start of the day. I have proven to myself that colder temperatures are the cause, car is normally parked outside in carport, but if I park it in my garage no message, I just live with it.
I contacted Richard and from my info given it sounds like my BCM is bad. When I called my service column lock wasn't coming on every time, but now it is. Could be the ignition also since its doing that.
I will try checking the grounds and see if that does anything.

I would like to know the troubleshooting steps he took to isolate the BCM being bad. Especially because you have a repeatable issue that can be duplicated by only manipulated the key.
Don't get distracted by random "check the grounds" suggetions. Just use the schematic to isolate.

Just by experience. He didn't say it was definite without looking at it, but according to the symptoms I had at the time it was likely. He's delt with tons of these and is very knowledgeable.
