ABS light on

I have a 94 Benz C 220. The ABS light is on and the speedometer is not working.. could it be the autometer speed sender? Does it sound like they are related

    Where is the VSS? Also, the radio was yanked out, there are hot wires undone. What color would it be, and where do i connect it?

    Thank you,

    Actuallly we found the problem to be the OVP Relay Fuse...Just in case anybody has this problem, thought you might find this helpful.

    Great question! Thanks to Mercedes Shopforum.com I was able to find someone with the same problem! The OVP relay is known as the over voltage protection relay.
    The OVP Relay is behind the plastic cover behind the battery. It will have a plastic lid on top and have either 1 or 2 fuses. It supplies 12v to the ABS computer, Idle Control Valve, and Fuel computer. Go to shopforum.com and you can find pics and diagrams!

    I am sorry I have no manuals on your car, just general knowledge of automotive related problems, I would suggest you contact the dealer for this info ( wire colors etc.). The VSS is located where the speedo cable would go on older cars on the side of the transmission case

There are actually two gears that you need to replace, a large one and then smaller one that rides inside it. You can purchase them both at www.fcpgroton.com These can also sometimes affect the operation of your speedometer. Do you by chance have an ABS and TRACS light on? If so the speedometer issue may be related to your ABS controller.

Gauges are on for anti locking brake and speedometer does not wor


since abs is relying on reading the current speed of the car, it is warning. since the speedo is down the abs cant do its job.

the speed is measurd by a small sensor on the gear box. cable go from there to the dashboard.

either the sensor is end of life or the cable is broken or the electrical contacts at the sensor are dirty. there are other possible causes as wall but those are rare. check these three first.

Abs brake light on wont shift until speedometer starts working


Could be your Speed sensor that would make the abs light come on because its not sensing the speed you are traveling. I have no Idea why when your gas gauge is on empty it won't shift. May be its the speed sensor and it was just happened to do it right when you where on empty. Does the speedometer work right or is it erratic? Let me Know this sound like and interesting problem I would like to work on and trouble shoot. Your ECM may be going too. There is so much going on Its hard to tell. But I would make sure the speed sensor is working properly first, Ok Talk at you soon. Thanks Bear001... Oh Yeah make sure all fluids are up and in good condition
