Being today's cars becoming rolling computers I bought this...
OBDLink MX+ OBD2 Bluetooth Scanner and also the
FORScan software to work with the scanner.
OBDLink is a diagnostic scan tool that not only reads all the computer operated systems (
Modules) in your car, but will also allow you to reprogram certain vehicle features or options, and this is where the FORScan software comes in. You'll need a license to unlock all the features though, including reprogramming.
OBDLink does provide a free phone app (Google or Apple store) allowing you to get a lot of real time information on your phone. You can't reprogram though. FORScan is Windows based only. Works under Windows 10.
Anyway, this is all new to me so I'm being extremely cautious before do anything. I did however buy the kit cause I wanted to enable daytime running lights on my car. In a brief run-through I was certainly presented with multiple options. That said, just prior to receiving the kit I discovered the headlight's accent lighting is being used as my DRL's, and since I like it I've not made any changes (yet). There are other modules for locks, horn, lights, and other stuff. It's also a great way to kill your car if you don't know what you're doing.
BTW while the scanner supports multiple car vendors, in quoting FORScan.... "
is designed especially for Ford, Mazda, Lincoln and Mercury vehicles", so... there's also a
FORScan forum.
