How to bleed 2005+ ABS modules from your garage

This writeup is for bleeding old fluid/air out of your ABS module from your garage.

Parts you will need:
OHP ELMconfig ELM327 - Wiring harness to connect to FORScan and the OBD
FORScan (you do not need a license)

Open FORScan and make sure the Connection options in Settings match this (if using the OHP ELMconfig ELM327 adapter)


Click on the car icon (Vehicle and interface information) and click "Connect to vehicle" (bottom left button) then follow the instructions that are presented.
Once FORScan connects to the vehicle, click on the wrench icon (Service functions), select "ABS Service Bleed" and click the play button.
A warning will pop up letting you know to use the service manual for this..click OK.
On the next pop up it will tell you to depress the brake pedal and hold, which is a two person job, but I use a Motive Power Pressure Brake Bleeder. So, when you click OK, just open the bleeder screw and allow the fluid to be pushed out but close it just before the percentage bar completes.
Repeat this for each wheel and finish bleeding the lines normally and you should be good to go!

Now just finish bleeding the lines normally and you're good to go.

in trying this on my car, I get a quick fail after 'energizing valves' occurs - how to troubleshoot this?

Looking online I found this post in the forscan forum (https://www.forscan.org/forum/viewt...sid=339aaff5c58546a30fa0679bc203ae3a&start=10), likely is your adapter. Which adapter are you using?

Edit: They actually have a thread detailing which adapters work and which to buy https://forscan.org/forum/viewtopic.php?f=4&t=6142

I've been using the OBDLink MX Bluetooth on 4 vehicles with zero issues

the car I'm building has a Gen3 coyote and separate GT500 ABS module (using 2009 build from Forscan team)
installed an OBDII port just for the ABS and added the resistor as well

I'd double check your wiring but I'd assume it's correct if you're able to communicate with the ABS at all. I have an extra adapter (the same one I used previously) you can have if you pay for shipping (dm me if interested), otherwise I'd reach out to the forscan team, they were very helpful to me previously.
