CONFIRMATION DRIVING PATTERN
CONFIRMATION AFTER TROUBLESHOOTING
HINT:
In this case, let the vehicle idle to complete the refresh charge. The refresh charge is complete when the Data List item Status of Battery Charge Control changes from "Refresh Charge Mode". (Usually, by idling the engine for 5 to 60 minutes with the auxiliary battery fluid temperature at 11°C (52°F) or higher, the refresh charge will be completed.)
If the engine is started with the hood open, the system determines that a jump start has occurred. Therefore, make sure that the hood is closed before starting the engine and driving the vehicle.

(a) Clear the DTCs.
Powertrain > Stop and Start > Clear DTCs(b) Start the engine and warm it up.
(c) Drive the vehicle at 7 km/h (4 mph) or more.
CAUTION:
When performing Confirmation Driving Pattern, obey all speed limits and traffic laws.
(d) Depress the brake pedal and stop the vehicle.
(e) Keep the engine stopped by stop and start control for 1 second or more. (Keep the shift lever in D.)
(f) Release the brake pedal with the shift lever in D to start the engine.
(g) Check that DTCs are not output.
