ABS Light On
Last weekend I had to make an abrupt stop to avoid rear-ending someone in my 1999 Super Duty with 7.3l, 4x4 with rear anti-lock breaks. Afterwards the ABS light was on and will not go off. I've tried the following; Disconnected the batteries and turned on the headlight, checked the fuse (its good), Tried another abrupt stop to the point the rear wheels locked up, and used a Autel MaxiCheck Pro OBS2 Scanner ABS Scan Tool. Check for code, there where none, check the ABS, no issue found, used the bleeding function, ABS light still on. When the scanner is hooked up an in service mode the ABS light goes out, but as soon as you exit service, it comes back on. Hope someone has an idea on why the ABS light will not go out.

That seems odd you can't find a code. Seems like you know what you're doing, but they are chassis codes and not powertrain code. My cheap $20 reader told me it was the front left speed sensor when my ABS light kicked on.
