- 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/RSC HU/CM operation click sound is heard.
- Performing the inspection above determines the following:
- The DSC/RSC HU/CM brake lines are normal.
- The DSC/RSC HU/CM hydraulic system is not significantly abnormal (including DSC/RSC HU/CM).
- The DSC/RSC HU/CM internal electrical parts (solenoid, motor and other parts) are normal.
- The DSC/RSC unit and DSC/RSC HU/CM output system wiring harnesses (solenoid valve, relay system) are normal.
- However, the following items cannot be verified.
- Malfunction with intermittent occurrence of the above items
- Malfunction of DSC/RSC HU/CM input system wiring harnesses and parts
- Extremely small leaks in the DSC/RSC HU/CM internal hydraulic system
