I have read a great deal on the forscan forum, having also downloaded and registered a copy of the software. One of the tweaks I am looking at is activating my Auto Relock mentioned elsewhere on these forumsif I get no success on warranty with this currently ongoing. I too have been looking at Forscan, with a view to tweaking some of the bells and whistles on my Edge, but not until the warranty expires. I've not had any trouble and hopefully never will for a long time! Helpful post in the forum about what obdII adapters to buy. I think personally I would be interested in finding fault codes incase its a simple fix. It isn't intuitive and most of the settings you need you can only find through web research. You really need to exercise care when fiddling with the ECU settings. I've used it to modify settings, eg enable drive away locking, change three flash indicators to four flashes. If you get a copy of the Service Manual there are a few downloads on the web if you search for them!! For the cost of the adapter, it gives you an understanding of what the problem may be and if you can fix it yourself, or at worst, verify what the dealer is telling you needs fixing and if your being taken for a ride or if they really understand what they are doing!

You need to see both CAN networks as most of the ECU's on the car are on one or the other but not both although a few are. One note is that the scan tools you can buy only look at a single CAN network most cars since There are also plenty of websites that show you how to modify an standard adapter and put a switch in yourself. Mine are Wifi, because it has a faster communication rate and my laptop doesn't have bluetooth! You also need to know what your doing for the latter!! Reading codes is pretty straight forward and can enable you to figure out if you have any issues. It's primary function is to read and display any fault codes that may be present. What else are the benefits of having it and is it a programme that you have on your laptop or a hand held unit that get plugged into the car. It is often mentioned on this forum and i'm guessing its a fault code reader only for Fords. I was just wondering in simple terms what Forscan is.
