    While doing this, check that the "Rear Motor Torque" value does not remain at 0 N*m continuously, but rather changes to indicate that the rear motor is operating.

    (Unless rear motor torque is restricted due to DTC output, the rear motor torque will not remain at 0 N*m continuously.)

  9. Enter the following menus: Powertrain / Rear Motor Generator / Utility / All Readiness.
  10. Check the DTC judgment result.

    HINT: 

    • If the judgment result shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system has a malfunction.
    • If the judgment result shows INCOMPLETE, perform driving pattern again.
