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.

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 and wait for 5 seconds or more. [*1]

HINT:

[*1]: Normal judgment procedure.

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


4.

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

5.

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

HINT:

After the repair, clear the DTCs. If the value of Data List item "Inverter Coolant Temperature" is not abnormal (110°C (230°F) or -40°C (-40°F)) when the ignition switch is turned to ON, the condition is judged as normal.

(If DTC P0A0011 is output, 110°C (230°F) will be displayed and if DTC P0A0015 is output, -40°C (-40°F) will be displayed.)
