ForScan ODB2 scanner w ELM327 USB

While working on your car have you ever wanted:
  • to find an ODB2 operational PID value (say fuel pressure or MAF)?
  • How about graph a PID value over time? Or compare multiple PID's over time?
  • Access a bi-directional PCM control such as test a solenoid or run the cooling fan?
  • Find out the DTC codes turning on the check engine light?
Do you have a Windows laptop? Do you have $30? If so consider getting the ForScan ODB2 software based scanner. This is a very powerful ODB2 scanner that has to be seen to believed especially considering the low price ($30). The data logging capabilities are nothing short of amazing. A complete game changer. However expect a steep learning curve with any ODB2 scanner

DIY Anti-theft (PATS) reprogramming:
Yes. It is "possible" to reprogram PATS yourself. HOWEVER you will need:
  • TWO different PATS key (cloned keys do not count). The keys must work mechanically. Do not even think about starting this process without this. Avoid super cheap ebay keys.
  • Windows laptop
  • ForScan software (free)
  • An extend license unlock code for ForScan(Needed for PATS). A 2 month demo is free at the time this was written.
  • A ELM237 USB dongle.
ForScan is an amazing product that is worth the price for the graphing and access to ODB2 PIDS alone. Being able to access bi-directional controls at will can make short work of some repairs. A real game changer.

Note: please don't ask me if ForScan will reprogram PATS for x model car. Nor ask me if such and such PATS key on ebay will work. I am NOT a shill for ForScan. I just think it's a very powerful product for an affordable price. If you want to know what it will do read the documentation. Better yet. Spend the $30 and find out for yourself. It can only help if the investment in learning is also made. IE, expect a steep learning curve.

In the same vein don't ask me if ForScan will work with "x" Dongle. I only have direct experience with the dongle posted. I encourage everyone to do their own research. YMMV.

Because I work on cars other than Fords I personally use the AutoEnginuity product. I can give first hand knowledge this product can reprogram PATS.

Note. If looking to replace a cluster with a salvage yard unit some model years require the PCM-ID to match. Which ForScan isn't able to update and may require using the Ford factory IDS tool.

Here's some more information that might help re-program a salvage yard PCM.

Note, a 72 hour subscription to the OFFICIAL motorcraftservice site is only $21.95 which is well within the range of the home DIY'er. With a valid subscription is possible to download full PCM configurations just like the dealer. Note, some special flash hardware may be required.
