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.

Click hereEngine / Hybrid System>HYBRID / BATTERY CONTROL>PA10 HYBRID BATTERY SYSTEM (for LITHIUM-ION BATTERY)>UTILITY

·

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

Click hereEngine / Hybrid System>HYBRID / BATTERY CONTROL>PA10 HYBRID BATTERY SYSTEM (for LITHIUM-ION BATTERY)>DTC CHECK / CLEAR



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 1 hour or more.[*1]

5.

Turn the ignition switch to ON and turn the GTS on.[*2]

6.

With ignition switch ON and wait for 10 seconds or more.[*3]

7.

Drive the vehicle on urban roads for approximately 10 minutes.[*4]

HINT:
·

[*1] to [*4]: Normal judgment procedure.

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

·

This DTC may not be stored if the vehicle is stopped or being driven at a constant speed.



8.

Turn the ignition switch to ON and turn the GTS on.

9.

Enter the following menus: Powertrain / HV Battery / 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 the normal judgment procedure again.




CAUTION / NOTICE / HINT

CAUTION:

Refer to the precautions before inspecting high voltage circuit.
