Actron CP9175 Needed Toolbox Item

I spent half of my life as a Ford Electronic Engine Control Specialist working on computer controlled vehicles and their sensors. I own a new GMC Sierra 1500 New Body Style pickup truck now, and with only a few thousand miles on it, the check engine light came on this morning. Since I have remote start as well on my truck, the computer is now preventing the remote starter from operating sensing that the vehicle has a problem. The truck runs great, but obviously the check engine light needs to be reset. The new GM vehicles will not allow you to use a combination of buttons to reset the trouble lights now, and within 3 minutes of using this code reader tonight, I have now reset my computer and cancelled the check engine light. GM vehicles are famous for having this light come on even when you may have switched brands of gas, or you have not tightened your gas cap enough. What is nice about this code reader is that it has the codes built into it, a library so to speak, and it will put into very easy to read words what systems are showing problems. If anyone had brought this vehicle into me for diagnosis only, it would have cost you around $85.00 for one hour minimum charge. Shops must charge a minimum one hour for things like this, however it may only take them 5 minutes to reset it. Which way do you want to go?
