Is it safe to drive with obd2 connected?
I have a 2010 ford escape and I want to know if driving with a ELM327 Bluetooth OBD2 scanner will harm the car's computer. Would it be safe to drive a car with something connected to the OBD2 port?
that’ll depend on the scanner. If it only reads to codes then you are okay (even so not sure why you would;-) If it places your vehicle into diagnostics mode then it is not okay to drive around with it. Take a look at your scanners manual and see what it says about the scanning etc.

You will notice immediately if it is not. your car may go into limp mode etc. I still wonder why you would want to drive around with your scanner attached :-)
Driving with an ELM 327 if perfectly fine for viewing what is going on with your vehicle or even resetting codes. I drive with a Bluetooth ELM 327 device connected to my 2011 Ford Escape all the time so I can use my phone like a heads up display and it works great. When diagnosing an EVAP code, I was able to reset the code while driving to see if it would come back on.
