To add to this correct post, one also has to match tire air pressure on all 4 tires for the same reason.
The computer is looking at rolling circumference comparisons. And the faster you go, the variation is lengthened beyond the computers lee-way.
See this a lot where the triggering fault is simply a low air pressure tire....
Computer Detected wheel rpm speed discrepiency.
