have a problem with the ride leveling system and the low brake pressure message. Does anyone have a wiring diagram of the ride leveling/low pressure system under the right front of the car, mine has 2 pressure valves with 2 wires coming out of it, yellow w/red and brown /black. I have power in one yellow wire but not the other yellow wire. I'm not real sure how the power goes through this system, that's why I am looking for a wiring diagram. thanks, Mike

 

You need to read Jaguar Publication S73.

I uploaded it many years ago to the large file area.
