My 97 RAM 1500 4X4 has the ABS/Brake light on.
The brake hydraulics are fine and it has a new Master Cyl.
I got some advice that maybe it was the rear axle speed sensor gone bad.
I disconnected the connection for it above the rear differential and the light remains on.
How can I trick out the sensor connection to make the light go out so I am sure this is the problem? Thanx!
