Not sure. In Pi Toolbox, I have a channel that's just a raw value of 0/1 for ABS. Similar discussion for an E46:

Otherwise, depending on the data rate of the wheel speed sensors, you could possibly derive how aggressively the ABS is braking each wheel -- which could be more useful. The above thread mentions doing this by creating a math channel to calculate the difference between the wheel speed sensors on the same axle.
I also have math channels to show aggression for braking, steering, and acceleration. |
LOL. That was me! Turned out I had a loose wire from battery to main fuse panel so under hard braking the car was actually shutting off. Took me 4 months and a replacement DSC module and master cylinder to figure it out. Once I recognized that infamy have bad connection, I was able to look through AiM and see rpms going to zero several times. Once car shuts off it will reset codes so I was never able to see it on track other than DSC kept turning itself back on and then the big lockup at Hallett. Gotta love AiM!
