I have a very slight pulsing on the brake pedal while braking. Want to see if it is the left front or right front or both, so I hooked up my Tech 2, drove the truck and hit the LF Dump Valve On, and got a message saying it cannot be done while the vehicle is moving.
Is there a scan tool that can do what I want? Is the ABS module programmed such that this request will always be ignored?
