Work Procedure

WARNING:

Never move the vehicle during "DAST CALIBRATION (MODE1)" because the steering gear is held in neutral position until ignition switch is OFF.
"DAST CALIBRATION (MODE1)" is additional service when removing/installing/replacing DAST parts or adjusting wheel alignment. "DAST CALIBRATION (MODE1)" is used in [Clutch phase learning] and [Steering rack neutral learning]. Using it incorrectly cause off-center. Refer to "ADDITIONAL SERVICE WHEN REPLACING OR REMOVING DAST PARTS" (Refer to Work Procedure ). and "TOE-IN ADJUSTMENT" [Refer to Inspection and Adjustment (alignment tester), Inspection and Adjustment (except alignment tester).] before performing it.

CAUTION:
