Confirmation Driving Pattern

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 [12/2023 - ]

• When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.

  Refer to DTC CHECK / CLEAR [12/2023 - ]

1. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
2. Turn the ignition switch off and wait for 2 minutes or more.
3. Enter the following menus: Powertrain / HV Battery / Active Test / Hybrid/EV Battery Refrigerant Cooling Control.
4. Perform the "Hybrid/EV Battery Refrigerant Cooling Control" Active Test for 20 minutes.[*1]

   HINT: 

   • In order to perform "Hybrid/EV Battery Refrigerant Cooling Control", the HV battery minimum temperature must be 20°C (68°F) and the refrigerant temperature must be 20°C (68°F) or higher.

     If the above conditions are not established, perform the "Hybrid/EV Battery Heater Relay" Active Test in an environment with an ambient temperature of 5°C (41°F) or higher and increase the HV battery temperature.

     The temperature will drop after the heater is stopped, so increase the values of "Hybrid/EV Battery Temperature 1 to 20, Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 1), Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 2)" in the Data List to 21°C (70°F) or higher.

     (At an ambient temperature of 5°C (41°F), "Hybrid/EV Battery Heater Relay" will need to be performed for approximately 10 hours.)

   • Perform this step with the A/C blower switch off.
   • [*1]: Normal judgment procedure.

     The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

5. Enter the following menus: Powertrain / HV Battery / Utility / All Readiness.
6. 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 or N/A, perform the normal judgment procedure again.
