Steady ESP warning?

Are active or passive sensors on my SLK. And what should be the resistive reading on the ohmmeter?

Hi,

I believe these are passive sensors. If you have a live data scan tool, you can check to see if there is a signal from each wheel and if they indicate the same speed.

If you don't have access to a scanner, you can check them manually. You will need a multimeter or voltmeter.

Here is a link that explains how to do it:

Let me know what you find.

Take care,
