1996 Mercedes Benz C220 4 cyl Two Wheel Drive Automatic

I have the Bake light on and the ABS light on and my speedo when out! All at the same time! I replaced both wheel sensors and no change. I also redid my ebrakes in the back and no change. I also have a light on saying I have a bad bulb someplace but everything outside the car checks good? Could this system pick up something on the inside I could be missing?

You may need to have the car scanned. If theSpeedo quits working, tehABS controller/PCM may not be getting speed signal from the VSS (Vehicle Speed Sensor), if that is the case the ABS, PCM wont know what speed to shift trans at or if the car is even moving when it comes to ABS. The 3rd brake light is working as well? Sometimes it gets overlooked when it comes to light inspections. If so remove the rear light mounting plates and see if there is any obvious melting of the board, same goes for the 3rd brake light.I dont believe the system monitors interior lights, but check license plate lights, brake lights, markers, everything
