Procedure to Clear Warning Lights (When not Clearing DTCs)
Procedure
1. Repair or replacement. 2. Turn the ignition switch to ON. 3. Drive the vehicle at 54 km/h (34 mph) or more for 3 seconds or more to clear the warning lights.

PROCEDURE

1.CHECK FRONT SPEED SENSOR (CHECK FOR FOREIGN MATTER)

Remove the front speed sensor.
