Pros: Can read codes, clear codes, veiw pids, network test. Cons: PATS function freezes up and has never worked for the past year I've used it. Cannot toggle PIDs in dataloger or see more then 6 at a time. On long yest drives I like to see multiple PIDS and press pause when the concern happens, but I often have to do this multiple times with 2 sets of PIDS active and screenshot them. Overall, does well but PATS needs to be fixed or deleted if it doesn't work.

Having the same issue as the others, as soon as I put my email in, it gives an error message. I have Uninstaller, reinstalled to attempt to re enter my email address, but it by passes the option and gives the error screen. Ford in general is honestly horrible. I've had nothing but bad experiences from the two vehicles I have, the Ford pass, now this app and anytime my vehicles are being serviced.

disregard the 1 star reviews from people without FMC credentials. the average person doesn't have the physical piece of equipment to go with this so it's not going to work for them or they think they are a mechanic and want to be able to scan their vehicle. here's an idea most new Ford's have connected vehicle and you can login to your account and see all the info from the vehicle that way. if you have FMC credentials then this app works great! if you don't then it ain't for you.
