PERFORM INITIALIZATION OF LINEAR SOLENOID VALVE AND CALIBRATION
PERFORM INITIALIZATION OF LINEAR SOLENOID VALVE AND CALIBRATION :
Description

INFOID:0000000004212604

Perform initialization of linear solenoid valve and calibration when the brake ECU, brake actuator or brake

stroke sensor is replaced. Follow the procedure to perform initialization.

NOTE:

• If there is a problem with the auxiliary battery (12 V) voltage, initialization of linear solenoid valve and calibra-

tion cannot be completed normally. Make sure to check the auxiliary battery voltage before performing initial-

ization of linear solenoid valve and calibration.

• If the actuator

′s temperature is high, initialization of linear solenoid valve and calibration may not be com-

pleted normally. In such a case, wait until the temperature decreases and then perform initialization of linear

solenoid valve and calibration.

• If the ignition switch is turned OFF, the brake pedal is operated or vehicle speed is input while the linear sole-

noid valve offset learning is being performed, the learning will be cancelled.

PERFORM INITIALIZATION OF LINEAR SOLENOID VALVE AND CALIBRATION :
Special Repair Requirement

INFOID:0000000004212605

1. Clear the stored value of linear solenoid valve and calibration data.
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 with the brake pedal released.
e. Clear the stored value of initialization of linear solenoid valve and calibration. Refer to

BRC-45, "CON-

SULT-III Function"

Using the CONSULT-III, perform initialization of linear solenoid valve and calibration.

2. Perform the initialization of linear solenoid valve and calibration.
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 linear solenoid valve offset learning is performed without turning the ignition switch ON, the learn-

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

• When the linear solenoid valve offset learning is interrupted, or the learning process is performed with

the shift lever not in the P position, DTC C1345 will be stored.

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

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

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

1 second to 0.5 seconds.

INSPECTION AND ADJUSTMENT

• While the linear solenoid valve is learning, the Electronically Controlled Brake warning lamp blinks at

intervals of 1 second. It blinks at intervals of 0.5 seconds after the completion of the learning.

• The time needed to complete initialization of linear solenoid valve and calibration varies depending on

auxiliary battery voltage.

• The Electronically Controlled Brake warning lamp blinks at 1 second intervals during initialization of lin-

ear solenoid valve.

• The Electronically Controlled Brake warning lamp blinks 0.25 seconds intervals if the CONSULT-III

prompts.

h. Select “TEST MODE END”.

PERFORM ZERO POINT OF YAW RATE/SIDE/DECEL G SENSOR
PERFORM ZERO POINT OF YAW RATE/SIDE/DECEL G SENSOR : Description

INFOID:0000000004212606

• After replacing the VDC relevant components or performing “Front wheel alignment adjustment”, clear and

read the sensor calibration data.

• Follow the chart to perform calibration.

PERFORM ZERO POINT OF YAW RATE/SIDE/DECEL G SENSOR : Special Repair
Requirement

INFOID:0000000004212607

CAUTION:

• While obtaining the zero point, keep the vehicle stationary and do not vibrate, tilt, move, or shake it.

• Be sure to perform this procedure on a level surface (with an inclination of less than 1 degree).
1. Clear the zero point calibration data.
a. Turn the ignition switch OFF.
b. Connect the CONSULT-III.
c.

Check that the steering wheel is centered and move the shift lever to the P position.

d. Turn the ignition switch ON with the brake pedal released.
e. Operate the CONSULT-III to erase the codes.
f.

Turn the ignition switch OFF.

2. Perform zero point calibration of the yaw rate/side/decel G sensor.
a. Turn the ignition switch OFF.
b. Check that the steering wheel is centered and move the shift lever to the P position.

CAUTION:

DTCs C1210 and C1336 will be recorded if the shift lever is not in the P position.

Connect the CONSULT-III.

d. Turn the ignition switch ON (READY) with the brake pedal depressed.
e. Select “TEST MODE” in “WORK SUPPORT” to start TEST MODE.
f.

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

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

1 second to 0.5 seconds.

NOTE:

• The zero point calibration is performed only once after the system enters the Test Mode.

• Calibration cannot be performed again until the stored data is cleared.

h. Select “TEST MODE END”.
i.

Turn the ignition switch OFF and disconnect the CONSULT-III.

Perform the zero point of steering angle sensor.
