A warning, it has been brought to my attention that some non asbuilt items for ABS module have been added. No they are not from me. I have asked that they be removed at least for our vehicle so will see what comes of it.

One reason I have always said do not touch is that you can brick the module and this may require a visit to you local dealer to fix. I have a complete list of changes for the ABS module but incompatible changes that do not apply to the firmware can still brick it and is one reason I never put the info forward.

Incompatible asbuilt changes on an ABS module can corrupt the memory. Some users have been able to disconnect and reconnect the battery to connect again and fix the asbuilt but other are not so lucky.

WARNING - DO NOT PLAY WITH THE ABS MODULE, YOU MAY BRICK YOUR VEHICLE.

** Update a battery disconnect/reconnect will bring it back to life, a module reset will not.

Confirmed on bench, if you have bricked it, disconnect and reconnect battery for a few minutes and it will come back. A module reset will not bring it back. Another user got away with doing this yesterday.

Even though it can be resolved, issue still stands, do not change ABS options, you will not gain additional fuctionality due to the firmware not supporting them in the first place.

End result. non asbuilt ABS parameters were added by mistake. These were originally from a 2014+ Fusion/Mondeo and will be removed in the next version. VIN parameter will stay.
