  2. Connect the M-MDS to the DLC-2.
  3. Set up an active command mode inspection according to the combination of commands below. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)] .)

    CAUTION:
    • When operating the solenoid valve and pump motor using the active command mode, make sure to keep the operation time within 2 s to prevent damaging the DSC HU/CM.
    NOTE:
    • When working with two people, one should press on the brake pedal, the other should attempt to rotate the wheel being inspected.
  4. Send the command while depressing on the brake pedal and attempting to rotate the wheel being inspected.
  5. When brake pressure is maintained and a DSC HU/CM operation click sound is heard, confirm that the wheel does not rotate. When brake pressure is being reduced and a DSC HU/CM operation click sound is heard, confirm that the wheel rotates.
    • Performing the inspection above determines the following:
      • The DSC HU/CM brake lines are normal.
      • The DSC HU/CM hydraulic system has no significant malfunction (including DSC HU/CM).
      • The DSC HU/CM internal electrical parts (solenoid, motor and other parts) are normal.
      • The DSC unit and DSC HU/CM output system wiring harnesses (solenoid valve, relay system) are normal.
    • However, the following items cannot be verified.
      • Intermittent malfunction of the above items
      • Malfunction of DSC HU/CM input system wiring harnesses and parts
      • Extremely small leakage in the DSC HU/CM internal hydraulic system
