Check Ride Control

I have a 2001 Lincoln Continential and the check air ride keeps coming on. The pump works on and off and the air bags don't leak. When it does work and fills up and levels out, when I'm driving, as soon as I hit the brakes the the check ride control light comes on and the air escapes. Sometimes as soon as I turn the car back on they re-inflate and other times the pump won't come on for a week or more. I pulled the air pump out today and took it apart and everything looked ok so I just reassembled it and put it back in. I'd appreciate your advice.

So if the pump will fill the system and function correctly then most likely we have an issue with a height sensor that is telling the module that the vehicle is lower then it actually is.

If the system drops then you have a pump issue or a leak. If you find a leak and fix that and still does not fill the system then most likely the leak caused the pump to burn up and it needs replaced now as well.

However, we need to check the voltage coming from the ride height sensor. Basically the sensor voltage will increase and decrease as the vehicle moves up and down.

Otherwise you will need to use a scan tool to monitor the position of the vehicle and make sure that matches the actual ride height.

I am attaching the wiring diagrams below for your review. Please let us know what you find or if you have questions. Thanks
