Hi Guys, what's required to reprogramme a new BCM on a h3?

 

I have access to a tech2 machine with the correct memory card, do I also need a security code? If so how can I find this, I didn't get it when I bought the car. I'm in the UK and no dealers here.

 

Or does the hummer require security software?

 

Thanks

A Vauxhall dealer should be able to help you

No. I know the updates and programming needs to be done by a dealership with GM licensing in their system. Some shops may be able to, but a GM dealership is your best bet. Normal going rate here is about $95 or 65 Pounds

Isn't there a way to do that via a GM website and a J2534 interface? Thought you just pay the fee on the site, and then download the program? I'm new to all this stuff, so I'm sure it's not this simple ....

      Trim level custom/pro

      Are you going to take long trips in it?  If so, try out the seats in the various trims. For me the lower trim level seats were not comfortable.

      I have a 2016 that I bought new and still own. I'm around 129,000 miles now. The biggest problem was a transmission failure about 2 years ago around 95000 miles. No warning, just failed while driving down a back road. A reman GM transmission installed and it's been fine ever since. A few other minor problems along the way. I am in no hurry to replace it. It's been paid off long ago and do plan on driving this as long as I can.   I will admit I am leery about all the additional electronics in the newer models and feel that it is just more potential problems. I think there's actually more than I would have wanted in this 2016 but so far so good. I think even if something major like lifter failure happened, it would still be cheaper to at worst, drop a new engine in than buy a new vehicle.

      I’ve own several successful businesses. I’ve bought homes and lived in different states. I’d witness several generations buy homes and survive in different economic circumstances. You get awful sippy when people have different experiences than you do. You live a life. I’ve lived a life. It seems our experience has been different. You can point out generalized statistics. Some people learn how to thrive when the odds are against them. Living in different states does make a difference in a persons quality of life and economic outcomes and opportunities. That’s a fact Jack. It’s my truth, my life. Hard work and long hours the right environment made my families life easier. And yes moving to a different state increased the odds of that happening. Stats are generalized. People who thrive don’t make excuses. They beat the odds. Others get mad and point to those statistics. I guess that’s you. My post pointed out how you helped people beat the odds. Somehow your panties got in a wad. Go figure.

      Good question, I don't remember for sure but I believe it was the HD. I will check and get back to you.

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences. "an account based on fact; a blur of fact and fancy." Something demonstrated to exist or known to have existed. "Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact." A real occurrence; an event. "had to prove the facts of the case." The American Heritage® Dictionary of the English Language, 5th Edition • More at Wordnik   If you'd like to disagree call your Senator or Representative and let him know his departments are in error. But you and I? We are not doing this.
