CONFIRMATION DRIVING PATTERN
- NOTICE:
-
When performing the normal judgment procedure, make sure that the driver door is closed and is not opened at any time during the procedure.
- 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.
·When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off.
Turn the ignition switch to ON (READY) and turn the GTS on.
Drive the vehicle at a speed of 3 km/h (2 mph) or more for 1 second or more. [*1]
Enter dealer mode or inspection mode, and drive the vehicle at a speed of 10 km/h (6 mph) for 1 second or more. [*2]
- HINT:
-
[*1] to [*2]: Normal judgment procedure.
-
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
Enter the following menus: Chassis / Brake Booster / 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, perform driving pattern again.
