Please explain the sequence of events in detail.

When driving and needing to engage the red button engine break to help reduce speed, ABS light comes on. It doesn’t seem to have any effect but I’m not sure. I do know that if while the engine brake is engaged, and you push on the pedal to increase speed The light will go out. But as soon as you take your foot off the throttle it will be lite. Once you shut the engine break off by turning the red switch off it goes dark. I’m guessing there’s a bad sensor. But my problem is finding a truck shop that has WABCO Tool box 12. I’ve located two, but neither can get us in anytime soon and one is a more undesirable drive.

I wonder if ABS doesn't work with engine brake active - thus it's warning you. Not sure how ABS COULD work with the engine brake engaged. Just a guess on my part.
