Hydraulic unit installation adjustment

Operate the pre-removal steps for the hydraulic unit.

(Refer to

P.35C-95

1. Remove all brake tubes.

2. Loosen the mounting bolt and nut of the hydraulic

unit bracket.

3. Install all brake tubes temporarily.

4. Shake hydraulic unit to all directions with both

hands to make the hydraulic unit bracket insulator
fit with the unit.

5. Install the hydraulic unit bracket with mounting

bolt and nut not to load the brake tube.

6. Install all brake tubes securely.

NOTE: Install the flare nut taking care not to let
the brake tube turn together.

7. Operate the post-installation steps of the hydraulic

unit. (Refer to

MEASURES FOR DISCHARGED
BATTERY

M1355006200102

CAUTION

Because the vehicle posture when applying the
brakes becomes unstable, do not leave ABS/ASC
disabled (for example, ASC-ECU connector dis-
connection).
When starting the engine using a booster cable with
the battery fully discharged, if you begin driving the
vehicle before the battery is fully charged, the engine
misfire may occur and you cannot start the vehicle.
This is because ABS/ASC consumes more electric
current to perform the self-check. In this case,
charge the battery fully.

ALL SENSOR CALIBRATION (G AND YAW
RATE SENSOR, STEERING WHEEL
SENSOR, BRAKE FLUID PRESSURE
SENSOR)

M1357003900034

CAUTION

Before carrying out the calibration, check that
the diagnosis code related to the steering wheel
sensor, G and yaw rate sensor, or brake fluid
pressure sensor is not set.

CAUTION

When the next operation has been completed,
carry out the calibration to make ASC-ECU learn
the neutral point of the steering wheel sensor, G
and yaw rate sensor, and brake fluid pressure
sensor.

• ASC-ECU replacement

CAUTION

Carry out the calibration under the following con-
ditions.

• The vehicle has one occupant (driver) only.
• Turn the steering wheel to set the wheels in

the straight-ahead positions.

• The brake pedal is not depressed. (The stop

lamp switch is OFF.)

1. Park the vehicle on a level surface.

CAUTION

Before connecting or disconnecting M.U.T.-III,
always turn the ignition switch to the LOCK
(OFF) position.

2. Before setting M.U.T.-III, turn the ignition key to

the LOCK (OFF) position.

3. Turn the ignition switch to the ON position.

4. Select "ABS/ASC/ASTC/WSS."

5. Select "Special function."

6. Select "Sensor calibration."

7. Select "All sensor calibration."

8. Before removing M.U.T.-III from the vehicle, turn

the ignition key to the LOCK (OFF) position.

G AND YAW RATE SENSOR
CALIBRATION

M1355009300324

CAUTION

Before performing calibration, check that the G
and yaw rate sensor-related diagnosis code is
not set.

CAUTION

After the next operation has been completed,
carry out the calibration to make ASC-ECU learn
the neutral position of the G and yaw rate sensor.

• ASC-ECU replacement

1. Park the vehicle on a level surface.

CAUTION

Before connecting or disconnecting M.U.T.-III,
always turn the ignition switch to the LOCK
(OFF) position.

2. Before setting M.U.T.-III, turn the ignition key to

the LOCK (OFF) position.

3. Turn the ignition switch to the ON position.

4. Select "ABS/ASC/ASTC/WSS."

5. Select "Special function."

6. Select "Sensor calibration."

7. Select "Lateral G sensor calibration."

8. Select "G sensor calibration."

9. Before removing M.U.T.-III from the vehicle, turn

the ignition key to the LOCK (OFF) position.

STEERING WHEEL SENSOR
CALIBRATION

M1355009200349

CAUTION

After the next operation has been completed,
carry out the following two operations:

1. Update the neutral position stored in the

steering wheel sensor.

2. Reset the calibrated value of the steering

angle stored in ASC-ECU.

• Alignment adjustment <Front>
• Steering wheel sensor (column switch assem-

bly) replacement, removal, installation

• ASC-ECU replacement

CAUTION

• Before performing the calibration, check if the

steering wheel sensor-related diagnosis code
is set in ASC-ECU.

• When the diagnosis code other than C121A is

set, carry out inspection according to each
troubleshooting procedure.

1. Park the vehicle on a level surface with tyres and

steering wheel positioned in a straight ahead
direction.

CAUTION

Before connecting or disconnecting M.U.T.-III,
always turn the ignition switch to the LOCK
(OFF) position.

2. Before setting M.U.T.-III, turn the ignition key to

the LOCK (OFF) position.

3. Ignition switch: ON

4. Select "Steering angle sensor."

5. Select "Special function."

6. Select "SAS Calibration."

7. Select and run "SAS Initialization." (Reusable

parts only)

NOTE:

•

Since the neutral position stored in the steer-
ing wheel sensor is no longer available, "SAS
Initialization" is displayed.

•

Since a new steering wheel sensor has no
neutral position, "SAS Calibration" is dis-
played.

8. Select and run "SAS Calibration."

9. Exit "Steering angle sensor" menu, and then

select "ABS/ASC/ASTC/WSS."

10.Select "Special function."

11.Select "Sensor calibration."

12.Select and run "SAS calibration."

13.Check whether the ASC-ECU-related diagnosis

code is set.

14.Erase the diagnosis code.

NOTE: Erase the diagnosis code C121A.

15.Before removing M.U.T.-III from the vehicle, turn

the ignition key to the LOCK (OFF) position.

BRAKE FLUID PRESSURE SENSOR
CALIBRATION

M1355024100189

CAUTION

Before performing calibration, check that the
brake fluid pressure sensor-related diagnosis
code is not set.

CAUTION

After the next operation has been completed,
carry out the calibration to make ASC-ECU learn
the neutral position of the brake fluid pressure
sensor.

• ASC-ECU replacement

CAUTION

Always perform the calibration with the brake
pedal released (stop lamp switch is turned off).
1. Park the vehicle on a level surface.

CAUTION

Before connecting or disconnecting M.U.T.-III,
always turn the ignition switch to the LOCK
(OFF) position.

2. Before setting M.U.T.-III, turn the ignition key to

the LOCK (OFF) position.

3. Turn the ignition switch to the ON position.

4. Select "ABS/ASC/ASTC/WSS."

5. Select "Special function."

6. Select "Sensor calibration."

7. Select "M/C pressure calibration."

8. Before removing M.U.T.-III from the vehicle, turn
