My wife was driving our '07 TCH on the freeway at about 70mph and it started to shake/shudder. She applied the brakes the dashboard lit up (brake sys warning (red), abs warning, e-brake, and slip indicator). She claims the engine was revving before everything happened as well. Toyota diagnosed it as a faulty abs actuator. Makes sense with most of the symptoms but the engine revving is still a mystery?! Anyone have any insight???
