Suspension Level Sensor

[Canna4.6is]

Hey all,

First time posting to the forum, but been kurking in the shadows for quite awhile.

After searching and reading about the self-leveling suspension on my e53 4.6is, I've decided that I need some more experienced input on my issue.

I've had the "Self-leveling Susp. Inac" message for about 6 months. No problems in ride height that i can tell, no leaking bags, and the air compressor is running fine.

So finally got INPA hooked up and read errors which showed right rear sensor. When i pulled up the analog info I saw that sensor was showing around .2V.

So ofc I went ahead and replaced the sensor. Upon starting and clearing error history, the same error returned. Analog info now shows 0V for the right rear sensor.

The question I have is how go about testing (at the connector) the input to the sensor to make sure it is getting what it needs before I return this and get another replacement.

I've attached the info, error report and analog output.

Thanks guys.
