If it's down on all four corners, you need to take it to a Jag dealer or specialty shop to pull the codes. I don't believe the standard OBD readers will pull the suspension codes. Not positive on that.

 

YOUR CORRECT kEN, YOU NEED WDS OR IDS TO LOOK AT AIR SUSPENSION AND THEN RUN THROUGH TESTING. cOMMON PROBLEMS ARE INSUFIECIENT AIR SUSPENSION PUMP. OPERATES BUT NOT ENOUGH PSI FAST ENOUGH TO FILL THE RESERVOIR AND LARGER FRONT AIR SPRINGS, FOLLOWED BY A BAD/LEAKING SPRING, THESE ARE THE MOST COMMON FAILURES, AND IF YOU DRIVE IT TO THE DEALING DEFLATED, YOU MAY END UP NEEDING NEW FRONT AIR SPRING ANYWAY DUE TO DAMAGE

 

Chill out with the caps.

 

you know most of the time Im at work using an Adp program that requires all cap commands, and since I usually forget when Im here I dont turn it off, sometimes I remeber and sometimes I dont as evident by partial sentences in caps, and or small case letters where a upper case should be. I have said this before about this. But let me be clear, IF YOU DONT LIKE IT LET ME KNOW AND ILL LEAVE AND YOU CAN FIRGURE OUT ALL YOUR OWN DAMN PROBLEMS.................................iM ABOUT SICK OF HEARING THIS CRAP LIVE WITH IT
