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 - ]
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for 2 minutes or more.
- Enter the following menus: Powertrain / HV Battery / Active Test / Hybrid/EV Battery Refrigerant Cooling Control / Data List / Hybrid/EV Battery Temperature 1 to 20, Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 1) and Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 2).[*1]
- Check that "Hybrid/EV Battery Temperature 1 to 20, Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 1) and Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 2)" is 20°C (68°F) or higher in the Data List.[*2]
HINT:
Conditions for performing "Hybrid/EV Battery Refrigerant Cooling Control" Active Test
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.)
- Set the vehicle to the following conditions.[*3]
Item Condition A/C Switch ON Blower Speed HI Set Temperature - MAX COLD when the ambient temperature is 25°C (77°F) or higher
- MAX HOT when the ambient temperature is less than 25°C (77°F)
HINT:
If the ambient temperature is from 25°C (77°F) to 30°C (86°F), perform the "Hybrid/EV Battery Refrigerant Cooling Control" Active Test within 1 minute from setting the above conditions.
- Check that "Hybrid/EV Battery Temperature 1 to 20, Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 1) and Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 2)" is 20°C (68°F) or higher in the Data List.[*4]
HINT:
Setting "A/C Switch" to "ON" and "Blower Speed" to "HI" in the vehicle may cause the refrigerant temperature to drop.
If the temperature has dropped lower than the conditions for performing the "Hybrid/EV Battery Refrigerant Cooling Control" Active Test, 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 temperature.
- Perform the "Hybrid/EV Battery Refrigerant Cooling Control" Active Test for 20 minutes.[*5]
- Turn the ignition switch off and wait for 1 minute or more.[*6]
- Enter the following menus: Powertrain / HV Battery / Active Test / Hybrid/EV Battery Refrigerant Cooling Control / Data List / Hybrid/EV Battery Temperature 1 to 20, Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 1) and Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 2).[*7]
- Check that "Hybrid/EV Battery Temperature 1 to 20, Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 1) and Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 2)" is 20°C (68°F) or higher in the Data List.[*8]
HINT:

- Set the vehicle to the following conditions.[*9]
Item Condition A/C Switch ON Blower Speed HI Set Temperature - MAX COLD when the ambient temperature is 25°C (77°F) or higher
- MAX HOT when the ambient temperature is less than 25°C (77°F)
HINT:
If the ambient temperature is from 25°C (77°F) to 30°C (86°F), perform the "Hybrid/EV Battery Refrigerant Cooling Control" Active Test within 1 minute from setting the above conditions.
- Check that "Hybrid/EV Battery Temperature 1 to 20, Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 1) and Hybrid/EV Battery Refrigerant Temperature (Duct Outlet 2)" is 20°C (68°F) or higher in the Data List.[*10]
HINT:
Setting "A/C Switch" to "ON" and "Blower Speed" to "HI" in the vehicle may cause the refrigerant temperature to drop.
If the temperature has dropped lower than the conditions for performing the "Hybrid/EV Battery Refrigerant Cooling Control" Active Test, 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 temperature.
- Perform the "Hybrid/EV Battery Refrigerant Cooling Control" Active Test for 20 minutes.[*11]
HINT:
[*1] to [*11]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / HV Battery / Utility / All Readiness.
- 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.
