CONFIRMATION DRIVING PATTERN
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
-
Connect the Techstream to the DLC3.
-
Turn the engine switch on (IG) and turn the Techstream on.
-
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
-
Turn the engine switch off and wait for 2 minutes or more.
-
Turn the engine switch on (IG) and turn the Techstream on.
-
Start the engine.
-
Wait for 2 seconds or more with the engine running. [*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 / Transmission / Utility / All Readiness.
-
Input the DTC: P271314.
-
Check the DTC judgment result.
