CAUTION:
• All hoses and piping (tubes) must be fr ee from excessive bending, twisting and pulling.
• Make sure there is no interference with other pa rts 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
parts. Replace applicable part with a new one, if necessary.
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
• Do not bend or twist brake hose sharply, or strongly pull it.
• Do not reuse drained brake fluid.
• After installation of the ABS actuator and electri c unit (control unit), refill brake system with new
brake fluid. Then bleed the ai r from the system. Refer to BR-14, "Bleeding Brake System"
.

ADJUSTMENT OF STEERING ANGLE
SENSOR NEUTRAL POSITION
ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION
DescriptionINFOID:0000000009463767
Refer to the table below to determine if adjustment of steering angle sensor neutral position is required.
×: Required –: Not required
Work ProcedureINFOID:0000000009463768
ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION
CAUTION:
To adjust neutral position of steering an gle sensor, make sure to use CONSULT.
(Adjustment cannot be done without CONSULT).
1.ALIGN THE VEHICLE STATUS
Stop vehicle with front wheels in straight-ahead position.
>> GO TO 2.
2.PERFORM THE NEUTRAL POSITION ADJUST MENT FOR THE STEERING ANGLE SENSOR
1. On the CONSULT screen, touch “WORK SUPPO RT” and “ST ANG SEN ADJUSTMENT” in order.
2. Touch “START”.
CAUTION:
Do not touch steering wheel whil e adjusting steering angle sensor.
3. After approximately 10 seconds, touch “END”. NOTE:
After approximately 60 seconds, it ends automatically.
4. Turn ignition switch OFF, then turn it ON again. CAUTION:
Be sure to perform above operation.
>> GO TO 3.
3.CHECK DATA MONITOR
1. Run vehicle with front wheels in straight-ahead position, then stop.
2. Select “DATA MONITOR”. Then make sure “STR ANGLE SIG” is within 0 ±2.5 °.
Is the steering angle within the specified range?
YES >> GO TO 4.
NO >> Perform the neutral position adjustment fo r the steering angle sensor again, GO TO 1
4.ERASE THE SELF-DIAGNOSIS MEMORY
Erase the self-diagnosis memory of the ABS ac tuator and electric unit (control unit) and ECM.
• ABS actuator and electric unit (control unit): Refer to BRC-33, "CONSULT Function (ABS)"
