Making the 11-14 S197 ABS work standalone

[RinerAuto]

Thanks to others pioneering, we have an alternative ABS swap from the common MK60. The 2011-2014 S197 ABS when paired with an RCM is able to operate as a standalone. Here's all the information that I have gathered to do this swap into my 1994 SN95. But I believe this can be done on any car. Hardest thing would be to figure out wheel speed sensors.


First what makes the 2011-2014 S197 ABS better than earlier Mustang's.

• 4 channel meaning each wheel has a dedicated brake line
• uses acceleration data from the RCM to
• has electronic brake distribution built in, to balance front and rear braking (no need for proportional valve)
• uses active wheel speed sensors, which are faster and work down to slower speeds than passive
• module is much lighter

Mounting

My car did not originally have ABS, so I am free to put it anywhere. Even though the module is quite light I wanted to keep it behind the front wheels for weigh distribution. There wasn't enough room to mount it in the engine bay. I decided to locate it in the drivers fender area where the cruise control servo motor would have been. The ABS module should be mounted upright so any air can be bled from the unit. Otherwise, what direction it is mounted I don't think matters. But I decided to mount it in similar orientation as factory. I also highly recommend running fender liners to keep rocks, water, and other debris from getting everywhere. Here is the mount I designed and had Send Cut Send make it. I'm really happy with how it turned out.



The RCM then needs to be mounted inside the car, preferably on the centerline and centrally located. I chose to mount it behind the park brake. I designed up a mounting plate that I also had Send Cut Send make and press in the studs. I then used scrap steel I had to level it and weld to the car.



HCU fittings/Plumbing

Item Number	ABS	2011-2014 S197
3	Front In	5/16" line, M14x1.5 inverted flare
2	Rear In	1/4" line, M12x1.5 inverted flare
4	Front Right Out	3/16" line, M10x1.5 inverted flare
5	Front Left Out	3/16" line, M10x1.5 inverted flare
6	Rear Right Out	3/16" line, M10x1.5 inverted flare
7	Rear Left Out	3/16" line, M10x1.5 inverted flare

The main supply lines to the HCU are quite larger than what my car used. It would be near impossible to run hard lines from my master cylinder which had 3/16" lines to the 1/4" and 5/16" input lines on the S197 HCU. Also the pitch is weird being 1.5. I decided to use -4AN flexible line with adapters at each end. The caliper outputs are all 3/16" hard lines.

Since I bought all the modules off the internet I didn't have the pigtails. Doing some research, I discovered that the ABS module is used in multiple different Fords of the era. I assume the RCM is as well. With the below list and some pictures, I went to the junkyard to see what I could find.

2010-2014 Mustang
2011-2014 F150
2011-2016 F250
2015-2017 Navigator
2015-2017 Expedition


I looked at an Expedition and a F-250. The Expedition had the same ABS but the RCM connectors looked different. The F-250 however matched up. I grabbed as much of the wiring as I could.



In my car I was able to reuse all of the wiring inside the car (rear wheel speeds, ignition power). I then had to run all new wiring for everything else. To get from inside the car to fender area I ran wires through the bulkhead connector that is already there.


For wheel speed sensors I bought new ones for a 2011-2014 Mustang and body side connectors from Ballenger Motorsports, pn: CONN-76049. For mounting the wheel speed sensors I did need to drill new holes at all four corners to orient the sensors correctly to read the stock SN95 tone wheels.

Nice, that's seriously scienced out. Nice work!

Thanks for sorting this out. I'd always thought the 2nd gen S197 Advance Trac ABS system would not work stand alone without communication to the PCM. I used the 1st gen from an 08 GT.
