All I really know is that it can get my particular truck out of limp mode when I need it to.
That is definitely a good thing, and as you have said, you were able to get the appropriate error code/s to diagnose and locate the fault.
I have a Bluetooth scan tool squirreled away somewhere (that I wrote off as not being useful), so I will load Torque up on my tablet and see what info I can get.
Thanks for your input.
