"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 Work Procedure .) before performing it.

CAUTION:

Be careful for the moving parts, steering wheel and front wheels are steered automatically when start "DAST CALIBRATION (MODE1)".
Do not rotate road wheels during the DAST calibration because the system is detected the vehicle running.
When the work stops (CONSULT freezing etc.), re-perform the work from the first step.

PREPARATION BEFORE DAST CALIBRATION
