Lift the car and inspect for leaks.
Use your scan tool to activate the compressor and see if it’ll function for more than three seconds.

I used my scanner it said the compressor takes too long to fill the bags and i tested the damper vavles all read 500miliamps whatever measurement it is and all were good exept vavle 1 on front right read 0 so I got a new compressor new vavles filter for it I was also woundering what would cause the bags psi to be uneven I got that code as well I also used the scanner to inflate deflate the bags and when I did it testing all 4 up and down it did not do anything at all
