height sensor test

when i did the test with the jumper wire it did everything normal until it got to the height sensor test compressor kicked on LF clicked then stopped.It also does it when i usally get in the car and i sometimes get the 90 sec message. Can you guys help me out?O yea and no leaks at all.

Look here.

I had a very similar problem with my 97 mark that I was just able to fix with Driller's help. I was wondering if your car was over inflating the front like mine was?
