Hello.
I just acquired a 2010 Silverado and do not have an issue reading the E38 but when I try to read the T43 the pop up commands me to update my firmware through the control panel because the Autocal has not been loaded into my device.
Please explain what this is all about or guide me through the process.
I have just updated the most resent downloads there is but have run into a road block here.
Tried to search for the answer but still not clear where my issue lies.
Thanks
