    Hello all,
    Looking to get some assistance on a suspension issue. I am getting HDC inactive, Air susp. inactive. The air bags keep pressure and when I stop the car I can feel and see the car lower then raise. I used an ODB reader and there are no errors reported. I tried the turning the wheel all the way to the left then to the right and it did not clear the errors. I would like some suggestions on what to look for.

    What diag did you use ?? If you have not cleared the hard fault it will not work properly until you do.

    except it may not be an eas problem, a faulty steering angle sensor causes same problem as does a wheel speed sensor

    You really need to check all the ecm on the car not just suspension as a fault in any one of them can and will stop the suspension from working.

    Thanks, I just replaced the battery about two weeks ago, and had someone test the voltage and everything is good.

    So, i got a ODB and tested everything. I have a couple of issues but the first is a CAN Bus issue with no codes. Everything I tested came back to a CAN Bus error.

    Generic ODB reader is no good. You need L322 specific diagnostics.
