Anti-lock brake feathering. Toyota Highlander.
Hi ... 2002 Highlander, in-law hand-me-down.
When starting up at very slow speeds (< 5 m.p.h.), the ABS system starts to "feather." I can't describe it any other way, other than to say it feels like the ABS system is kicking in. Since my foot is not on the brakes, I can't feel it there, but the ABS light on the dash does light up, and it makes the familiar sound.
It happens intermittently, and never at any speeds other than a very slow one, and trying to accelerate, especially in a parking lot.
