Procedure to clear warning lights (When not clearing DTCs)
Procedure
|
-
Repair or replacement.
-
Turn the engine switch on (IG).
-
Drive the vehicle at 11 km/h (7 mph) or more for 1 second or more to clear the warning lights.
|
PROCEDURE
(a) Check that all 4 tires are of correct size, are inflated to the correct pressure, and do not show excessive signs of wear.
Click here
HINT:
If a tire is deformed or an incorrectly sized tire or wheel is installed, this DTC may be stored.
