  2. 2

    Check the motor and brake components (e.g., measure coil resistance, inspect for mechanical binding or damage).

  3. 3

    Check the brake cable and motor cable for continuity, short circuits, or physical damage along their entire length.

  4. 4

    Reinitialize the drive bus by performing a Power Off / Power On cycle of the entire system.

  5. 5

    Check the KSP module for diagnostic indicators related to brake control.
