- Connect the M-MDS to the DLC-2.
- Set up an active command mode inspection according to the combination of commands below. (See

.)
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.

- Send the command while rotating the wheel being inspected by hand in a forward direction.
- Confirm that the wheel does not rotate easily while a DSC HU/CM operation click sound is heard.
- 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
