1. A air compression and storage system installed on a motor vehicle providing monitoring of system operating variables for conformance with predefined values, the system comprising:

  • a compressed air storage tank and air distribution system;

    an air compressor coupled to the compressed air storage tank and air distribution system for charging the air storage tank;

    a governor responsive to pressure in the compressed air storage tank and air distribution system controlling cut-in and cut-out of the air compressor;

    an air pressure sensor located in communication with the compressed air storage tank and air distribution system for sensing air pressure and generating an air pressure signal; and

    a vehicle body computer connected to receive the air pressure signal and programmed to respond to values assumed by the air pressure signal for determining leakage rate and charging rate related values for the compressed air storage tank and air distribution system and for providing warning signals where leakage and changing rate values fail the predefined values.
