Procedure to clear warning lights (When not clearing DTCs) Procedure
- Repair or replacement.
- Turn the ignition switch to ON.
- Drive the vehicle at 11 km/h (7 mph) or more for 1 second or more to clear the warning lights.
PROCEDURE
|
1. | PRE-CHECK |
(a) Check that all 4 tires are of correct size, are inflated to the correct pressure, and do not show excessive signs of wear.

(d) Start the engine.
(e) Perform a road test under the same malfunction conditions recreated based on the Freeze Frame Data or customer problem analysis.
(f) Check the value of Wheel Speed.
OK:
The difference between the value of RL Wheel Speed and all other values is less than 6%.
HINT:
If the result of the road test is within the specified range, it is possible that this DTC was stored due to a particular situation such as wheelspin.
