DIY Rear Brake Pad Change

[VenomKia]

I'm starting to gather my intel on how to do it, and I've seen videos on people who manually back the parking brake out on the rear of the car. I'm trying to do this the correct way, and not have to manually move it. So my question is, I have a Harbor Freight Zurich ZR-Pro car diagnostic and it's a nice piece of hardware when diagnosing engines and of course when you have things like this to change the brakes. I was testing last night, and found the service menu in the ZR-Pro to put the parking brakes into service mode. It says to have the Ignition On, Engine Off, and then Continue, however the screen in the car flashes Check ESC, and the ZR-Pro says "Check Condition" Any mechanics who have done this with the computer, do you need to turn the ESC off in order to use a tool to move the parking brake?

Thanks in advance! Any assistance is appreciated!
