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>MOTOR GENERATOR CONTROL SYSTEM>UTILITY

·

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

Click hereEngine / Hybrid System>HYBRID / BATTERY CONTROL>MOTOR GENERATOR CONTROL SYSTEM>DTC CHECK / CLEAR



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.

Turn the ignition switch to ON (READY).

4.

With the vehicle stopped, move the shift lever to P.

5.

Depress the accelerator pedal to start the engine.

6.

Depress the accelerator pedal and maintain the engine speed at 1000 rpm or more for 5 seconds or more.

NOTICE:

As the state of charge of the HV battery may be low after driving in fail-safe mode, it will automatically be charged for 5 to 10 minutes with ignition switch ON (READY) after repairs have been performed.


7.

Enter the following menus: Powertrain / Motor Generator / Utility / All Readiness.

8.

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.
