Perform Initialization of Linear Solenoid Valve and Calibration
PERFORM INITIALIZATION OF LINEAR SOLENOID VALVE AND CALIBRATION: DescriptionPerform 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 calibration cannot be completed normally. Make sure to check the auxiliary battery voltage before performing initialization of linear solenoid valve and calibration.
^ If the actuator's temperature is high, initialization of linear solenoid valve and calibration may not be completed 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 solenoid valve offset learning is being performed, the learning will be cancelled.
PERFORM INITIALIZATION OF LINEAR SOLENOID VALVE AND CALIBRATION: Special Repair Requirement
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, "CONSULT-III Function". Consult-III Function
f. 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 learning 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 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:
^ 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 linear solenoid valve.
^ The Electronically Controlled Brake warning lamp blinks 0.25 seconds intervals if the CONSULT-III prompts.
h. Select "TEST MODE END".
