CMU monitoring items



  • Available items are established for these items to see the CMU control status.
  • These items are difficult to clearly show the specification value because the values much vary depending on the slight difference in the measuring conditions, in the environment or in the chronological change of the vehicle.The check conditions, displayed ranges and value variations are described.
