If the vehicle as is left as is for 24 hours, the value of "Hybrid/EV Battery Temperature" will be almost the same as the ambient temperature.
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.
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
P0A9B2A, P0AC52A, P0ACA2A, P0AE82A, P0BC22A, P0C332A:
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
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.
Turn the ignition switch to ON and turn the GTS on.
Drive the vehicle for approximately 10 minutes according to the freeze frame data items "Vehicle Speed", "Accelerator Position", "Hybrid/EV Battery Temperature 1 to 6" and "Hybrid/EV Battery Current" when ambient temperature is -10°C (14°F) or higher.[*1]
Check that the output of each battery temperature sensor varies.
Check that the difference in output between each battery temperature sensor is not excessively large.
[*1]: 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.
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 the normal judgment procedure again.
P306562, P306A62:
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
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.
Turn the ignition switch to ON and turn the GTS on.
With ignition switch ON and wait for 10 seconds or more when the ambient temperature is -10°C (14°F) or higher.[*1]
Check that the difference in output between each battery temperature sensor is not large.
[*1]: 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.
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.
Refer to the wiring diagram for DTC P0A9B11.
Refer to the precautions before inspecting high voltage circuit.
After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) auxiliary battery terminal.
When disconnecting and reconnecting the auxiliary battery
When disconnecting and reconnecting the auxiliary battery, there is an automatic learning function that completes learning when the respective system is used.
Check for DTCs.
