• If the ABS actuator and electric unit (control unit) is replaced, make sure to adjust position of steering angle

sensor. Refer to

BRC-124, "ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION : Spe-

cial Repair Requirement"

CAUTION:

• All hoses and piping (tubes) must be free from excessive bending, twisting and pulling.

• Make sure there is no interference with other parts when turning steering both clockwise and coun-

terclockwise.

• The brake piping is an important safety part. If a brake fluid leak is detected, always disassemble the
