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.

- Connect the Techstream to the DLC3.
- Turn the power switch on (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the power switch off and wait for 2 minutes or more.
- Turn the power switch on (IG) and turn the Techstream on.
- With power switch on (IG) 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.
- Enter the following menus: Powertrain / Motor Generator / 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.
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 power switch is turned on (IG), 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.) PROCEDURE
