Confirmation Driving Pattern

WARNING: This page is about a different variant/trim than selected.

HINT: 

After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

Refer to UTILITY [12/2019 - 11/2023]

  1. Connect the GTS to the DLC3.
  2. Turn the ignition switch to ON and turn the GTS on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  4. Turn the ignition switch off and wait for 2 minutes or more.
  5. Turn the ignition switch to ON and turn the GTS on.
  6. Apply the parking brake and secure the wheels using chocks.
    NOTE:

    Perform this test with the AUTO function (shift-linked function) of the electric parking brake system off.

    HINT: 

    When the parking brake indicator (red) is illuminated after the electric parking brake switch assembly has been pulled to the lock side, the maximum amount of braking force is applied if the electric parking brake switch assembly is pulled to the lock side one more time.

  7. Fully apply the parking brake and chock all 4 wheels. Firmly depress the brake pedal, turn the ignition switch to ON (READY) and with the shift lever in D. Depress the accelerator pedal to start the engine and increase the engine speed. This will cause the "Hybrid Battery SOC" to increase.

    If the charge current drops, release the accelerator pedal and then depress it again to maintain charging.

  8. Select "WIN Control Limit Power" in the Data List and check that charging stops when "WIN Control Limit Power" reaches 0 kW.
  9. Check that charging stops when the Data List item "Hybrid Battery SOC" reaches the upper limit.
  10. Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.
  11. 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.
