Q: ride height sensor

asked by

Randi C

on December 18, 2017

I just purchased a 2013 cadillac escalade and have noticed that there is not a air ride sound when starting the vehicle or even when adding weight to the vehicle. The ride is incredibly rough on the rear end and feels like I have 3 wheels when going over speed bumps. The service suspension light is NOT on and it is not throwing any codes when hooked up to a diagnostic. I recently removed the ESCM and it just now triggered the service suspension light on the display. However, this message was not coming on before when the ESCM was still connected. I have put 12v on the air compressor and it works as well as checked all fuses and they're all fine. I was told it could be my ride height sensor but I am not sure which of the 4 is not working or if they're all not working. Help!

My car has 88000 miles.
