    2009 GMC Acadia, requesting access failed

    As the topic says, when I connect to do a read via editor, I get this message. I'll attach a screenshot, the Acadia is showing up as an Envoy. I downloaded v. 2.24 today, and the interface updated OK. I have no problems connecting to my laptop, and do not have another laptop to try. The VCM scanner reads the vehicle OK, I can read some DTCs stored.

    I've read through some older threads here where this was a problem and the consensus was the VCM is tunerlocked. We've owned this vehicle since new, and it has never had the VCM modified, so it can't be tunerlocked. I've also waited up to 30 seconds before trying to connect with the same result, and retrying it gives the security access denied message in the attached screenshot.

    This vehicle does not show up as supported on the main vehicle list, but a post by Bill in April 2014 said it was now supported. I'll copy the relevant part-
    04-16-2014 Additional V6 support released

    Some of you may have already received an email from me in the last day or so but recently we released support for a ton of new vehicles so I'm starting a list of the newest

    09-11 GMC Acadia V6




    Any help is appreciated.

    You need to e-mail support and request access to 2.25. Your vehicle is not supported by 2.24.

    2.25 did the trick for me, thanks.
