96 E320 (ABS) and (ETS) light ON

[davidlee]

I have a 96 320 RWD and the ETS and ABS lights are on. I was told that it could be a wheel speed sensor that has failed, any way to find out which one it is without taking it in to a shop and paying a diagnose fee?
thanks for any help.

Yes, you can unplug the sensors and measure the resistance. All 4 should read the same. While you're there, clean the hub. It has those teeth that the sensors read. Those get dirty and trigger the light.
If you don't feel like pulling the wheels off, find what pins they connect to on the ABS module, attached to the ABS pump. And measure it there.

Brake light switch?
