CONFIRMATION DRIVING PATTERN
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
- After repairs have been completed, clear the DTCs 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.
Click here
- 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.
-
Perform the D Position Shift Test inspection in Road Test. [*1]

HINT:
[*1]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Stop the vehicle.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P096014.
-
Check the DTC judgment result.
