Anyone else had this problem? The vehicle in question is a 2004 Silverado with a 6.6 liter LB7 diesel. I have the MPVi pro interface with the latest version of HP Tuners. I can connect with VCM Scanner just fine, but when I try to "read entire" it stops at the "Preparing VCM" step and comes up with this error: "Boot Loader Download request timed out".
It was suggested that the truck may have a tune on it already and is possibly locked. Knowing that, I took it to the dealership for a reflash and the tech was unable to do so using his Consult programmer.
Any ideas, guys?
Thanks,
Steve
