Hi mknight35,
That would be a code reader not a scanner. In this instance the scanner is required to open the 4 solenoid valves in sequence to bleed the HCU. The HCU allows brake fluid to flow through to the 4 outlet brake lines that lead to individual brake calipers to bleed the brakes. But air gets trapped inside the HCU when you open remove and replace the two brake line inputs from the master cylinder so you need to bleed it. The scanner is attached to the Data Link Connector (DLC), the OBD2 port, and accesses the ABS module to open each specific solenoid valve while you bleed that brake circuit, then close that solenoid and move onto the next brake circuit until all 4 brake lines are bled.
I think a Ford dealer will charge about $85 to $145 depending on the services requested. But the scanner is a few thousand dollars. There is an Autoenginuity scanner that needs a laptop and Ford specific software for several hundred dollars.
Good luck.

Hi mknight35,
OK, let us know how you got along with the installation, and the bleeding. You know that you can bleed the system normally and it will work fine, except for the ABS, so you can drive to the dealer for the ABS bleed.
Good luck.
