PERFORM ADJUSTMENT OF STROKE SENSOR
PERFORM ADJUSTMENT OF STROKE SENSOR : Description

INFOID:0000000004212608

After removing or adjusting brake stroke sensor, adjustments are necessary.

PERFORM ADJUSTMENT OF STROKE SENSOR : Special Repair Requirement

INFOID:0000000004212609

1. Clear the stored value of stroke sensor data.
a. Connect the connector to the brake stroke sensor.
b. Connect the CONSULT-III with the ignition switch OFF.
c. Turn the ignition switch ON.
d. Reading the “STROKE SEN” value shown in the DATA MONITOR, slowly turn the brake stroke sensor to

the right and left to adjust the value to the standard voltage.

e. Fully tighten the mounting bolts.

CAUTION:

Do not depress the brake pedal after turning the ignition switch ON. 

f.

Move the shift lever to the P position.

g. Turn the ignition switch ON with the brake pedal released.
h. Clear the stored value of stroke sensor.
i.

Using the CONSULT-III, perform adjustment of stroke sensor.

2. Perform the adjustment of stroke sensor.
a. Turn the ignition switch OFF.
b. Connect the CONSULT-III.
c. Move the shift lever to the P position.
d. Turn the ignition switch ON (READY) with the brake pedal depressed.

NOTE:

• If the stroke sensor offset learning is performed without turning the ignition switch ON, the learning pro-

cess may not be completed properly because of insufficient auxiliary battery voltage.

• When the stroke sensor offset learning is interrupted, or the learning process is performed with the shift

lever not in the P position.

e. Select “TEST MODE” in “WORK SUPPORT” to start TEST MODE.
f.

Leave the vehicle stationary without depressing the brake pedal for 1 to 2 minutes.

g. Check that the interval between blinks of the Electronically Controlled Brake warning lamp.

NOTE:

• The time needed to complete adjustment of stroke sensor varies depending on auxiliary battery voltage.

• The Electronically Controlled Brake warning lamp blinks at 1 second interval during adjustment of stroke

sensor.

h. Select “TEST MODE END”.

ment

INFOID:0000000004212611

1. After the procedure, perform straight-ahead driving for 5 seconds or more at 35 km/h (22 MPH) or more.
2. After driving, check that VDC warning lamp is OFF.

TEST MODE PROCEDURE

INFOID:0000000004212612

WARNING LAMP AND INDICATOR LAMP INITIAL CHECK

1. Release the parking brake.

CAUTION:

Before releasing the parking brake, move the shift lever to the P position for safety.

NOTE:

When the parking brake is applied or the level of the brake fluid is low, the brake warning lamp comes on.

2. When the ignition switch is turned ON, check that the ABS warning lamp, brake warning lamp, VDC warn-

ing lamp, Electronically Controlled Brake warning lamp and SLIP indicator lamp come on and remain ON

until the ignition switch is turned ON (READY).

NOTE:

If the ECU stored a DTC, the ABS warning lamp, brake warning lamp, VDC warning lamp, Electronically

Controlled Brake warning lamp and SLIP indicator lamp come ON. If the indicator remains ON or does not

come ON, proceed to troubleshooting for the lamp circuits listed below.

ACCELERATION SENSOR CHECK (CONSULT-III)

1. Keep the vehicle stationary on a level surface for 1 second or more.

NOTE:

Acceleration sensor check can be performed with the master cylinder pressure sensor check below.

MASTER CYLINDER PRESSURE SENSOR CHECK (CONSULT-III)

1. Leave the vehicle in a stationary condition and release the brake pedal for 1 second or more, and quickly

and continuously depress the brake pedal with a force of 98 N (10 kgf, 22 lbf) or more for 1 second.

2. Check that the ABS warning lamp stays ON for 3 seconds.

NOTE:

• Ensure that the ABS warning lamp comes ON.

• While the ABS warning lamp stays ON, continue to depress the brake pedal with a force of 98 N (10 kgf,

22 lbf) or more.

• The ABS warning lamp comes ON for 3 seconds every time brake pedal operation above is performed.

• Requirement for pedal operation are more than 50 MPa/sec. and 4 MPa at master cylinder pressure

sensor.

WHEEL SENSOR CHECK (CONSULT-III)

1. Check the wheel sensor signal.
a. Drive the vehicle straight ahead. Accelerate the vehicle to a speed 45 km/h (28 MPH) or more for several

seconds and check that the ABS warning lamp goes OFF.

NOTE:

The sensor check may not be completed if wheelspin occurs.

2. Stop vehicle.

CAUTION:

• Before performing the wheel sensor check, completed the acceleration sensor and master cylin-

der pressure sensor checks.

• The wheel sensor check may not be completed if the wheel sensor check is started while turning

the steering wheel or spinning the wheels.

• After the ABS warning lamp goes OFF and if the vehicle speed exceeds 80 km/h (50 MPH), a sig-

nal check code will be stored again. Accelerate or stop the vehicle before the speed reaches 80

km/h (50 MPH).

BASIC INSPECTION

• If the signal check has not been completed, the ABS warning lamp comes ON while driving and

the ABS system does not operate.

NOTE:

When the sensor check has been completed, the ABS warning lamp goes OFF while driving.

3. Check the VDC sensor.

YAW RATE SENSOR CHECK (CONSULT-III)

1. Check the zero point voltage of the yaw rate sensor.
a. Keep the vehicle in a stationary condition on a level surface for 1 second or more.
2. Check the output of the yaw rate sensor.
a. Move the shift lever from P to the D position and drive the vehicle at a speed of approximately 5 km/h (3

MPH), and turn the steering wheel either to the left or right 90

° or more until the vehicle makes a 180°

turn.

b. Stop the vehicle and move the shift lever to the P position. Check that the brake warning buzzer sounds

for 3 seconds.

NOTE:

• If the brake warning buzzer sounds, the sensor check is completed normally.

• If the brake warning buzzer does not sound, check the brake warning buzzer circuit, then perform the

sensor check again.

• If the brake warning buzzer still does not sound, there is a malfunction in the yaw rate sensor, so check

the DTC.

• Make a 180

° turn. At the end of the turn, the direction of the vehicle should be within 180° ±5° of its start

position.

• Do not spin the wheel.

• Do not turn the ignition switch OFF while turning.

• Do not move the shift lever to the P position while turning, but changing in the vehicle speed, or driving

in reverse is possible.

• Complete the turn within 20 seconds.

END OF SENSOR CHECK (CONSULT-III)

1. If the sensor check is completed, the ABS warning lamp is off while the vehicle is driving.

CAUTION:

• When the yaw rate sensor, acceleration sensor, wheel sensor, and master cylinder pressure sen-

sor checks are completed, the sensor check is completed.

• If the sensor check is not completed, the ABS warning lamp comes ON even while the vehicle is

driving and the ABS does not operate.

READ DTC OF TEST MODE (SIGNAL CHECK) FUNCTION (CONSULT-III)

1. Read the DTC(s) by following the tester screen.

CAUTION:

• If only the DTCs are displayed, repair the malfunction area and clear the DTCs.

• If the DTCs or Test Mode codes (DTC of signal check function) are displayed, repair the malfunc-

tion area, clear the DTCs and perform the Test Mode inspection.

NOTE:

Refer to the list of DTC.
