Firestone IntelliRide system

The Diagnostic tool file 'Monaco - IntelliRide Controls Calibtarion Diagnostic Tool 2.1.1.msi' can be downloaded below. It only works with Windows 98, 2000, and XP.  You will need a 9-pin Serial cable to connect to the ECU. (Local Radio Shack carries this).

The ECU is located in the side panel underneath where the switch panel is located. 

The PC Tool must be used to reset heights and horizon levelling.

Ride Height setting via PC Tool:

  • Air Springs should be 9-5/16” in height from the top of the B-Plate to the bottom of the Piston. 
  • When it’s at 'Ride-Height', the front sensors must be between 1.92-2.68v and the rear sensors must be between 2.44-3.34v.  If they are outside of that range, the software will not save the calibration values.  The software program will display the voltages.
