Check engine, brake, abs on dash. How many sensors and locations. What are steps to fix problem.Oh forgot speedometer works till I use brakes. Help !

You need to put it on a scanner.. The speedo is controlled by a sensor on top of the rear diff. IT can also cause an ABS light

Jim.... Check and make sure the fuses are good under the hood.... The ones in the black distribution box... Make sure the fuses under the Black clip and the Yellow or White are good.... Those are the main fuses, sounds to me like one of those blew out?
