INITIALIZATION





1. STEERING ANGLE SENSOR INITIALIZATION (to obtain a tire angle (during straight-ahead driving) signal)
(a) Turn the power switch ON (IG), and check that the master warning light and VSC/ABS warning lights illuminate for a few seconds.

NOTICE:
If the warning lights remain on or blink, repair the applicable system.

(b) Drive the vehicle on a straight road at 35 km/h (22 mph) or more for 5 seconds or longer.

HINT:
^ At this point, the steering wheel will still remain off-center by 5 to 10 degrees.
^ In this step, the neutral position of the steering wheel is restored from the steering control ECU memory.

(c) Confirm that steering angle sensor initialization is completed (when using the intelligent tester).
(1) Enter the VGRS menu using the intelligent tester. Select "STRAIGH ANG FLG" from "DATA LIST". Check if the steering angle sensor has obtained a tire angle (during straight-ahead driving) signal.
Standard:
"VALID" is displayed on the tester screen.
(d) Confirm that steering angle sensor initialization is completed (when not using the intelligent tester).
(1) Drive the vehicle on a straight road at 60 km/h (37 mph) or more for 30 seconds or longer.
(2) Stop the vehicle (engine running).
(3) Slowly turn the steering wheel from lock to lock.
(4) If it turns approximately 2.7 turns, steering angle sensor initialization is completed. If it turns approximately 3.2 turns, steering angle sensor initialization is not completed.

NOTICE:
If the steering wheel turns approximately 3.2 turns, drive the vehicle on a straight road at 35 km/h (22 mph) or more for 5 seconds or longer. Then confirm the initialization again.
