We use a mastertech. Not only pulls codes, but can monitor the data stream and run function test and more.
The abs system is separate from the hydrolic brake system. I expect that you have a wheel speed sensor going bad. May be part of the wheel bearing and hub assy. Take a look for the wiring harnesses going to the sensors and check for damage or bad connections first.
You will need to pull codes from the body control module to narrow it down as you know.
