ON−VEHICLE INSPECTION
1. CONNECT HAND−HELD TESTER:
Connect the hand−held tester to the DLC3.
Start the engine and run it at idle.
Select the ACTIVE TEST mode on the hand−held tester.
HINT: Please refer to the hand−held tester operator’s manual for further details.
2. INSPECT ACTUATOR MOTOR OPERATION
With the motor relay ON, check the actuator motor operation noise.
Turn the motor relay OFF.
Depress the brake pedal and hold it for about 15 seconds. Check that the brake pedal cannot be depressed.
With the motor relay ON, check that the pedal does not pulsate.
NOTICE: Do not keep motor relay ON for more than 5 seconds continuously. When operating it continuously, set the interval of more than 20 seconds.
Turn the motor relay OFF and release the brake pedal.
3. INSPECT RIGHT FRONT WHEEL OPERATION
NOTICE: Never turn ON the solenoid which is not described below.
With the brake pedal depressed, perform the following operations.
Turn the SFRH and SFRR solenoid ON simultaneously, and check that the pedal cannot be depressed.
NOTICE: Do not keep solenoid ON for more than 10 seconds continuously. When operating it continuously, set the interval of more than 20 seconds.
Turn the SFRH and SFRR solenoid OFF simultaneously, and check that the pedal can be depressed.
Turn the motor relay ON, and check that the pedal returns.
NOTICE: Do not keep motor relay ON for more than 5 seconds continuously. When operating it continuously, set the interval of more than 20 seconds.
Turn the motor relay OFF and release the brake pedal.
4. INSPECT OTHER WHEEL OPERATION
As in the same procedure, check the solenoids of other wheels.
HINT:
Left front wheel: SFLH, SFLR
Right rear wheel: SRRH, SRRR
Left rear wheel: SRLH, SRLR
REPLACEMENT
1. DRAIN BRAKE FLUID
NOTICE: Wash off the brake fluied immediately if it comes into contact with a painted surface.
2. REMOVE BRAKE ACTUATOR WITH BRACKET
Using SST, disconnect the 6 brake lines from the actuator.
SST 09023−00101
Use tags or make a memo to identify the place to reconnect.
Disconnect the brake actuator connector.
Remove the 3 nuts and brake actuator with bracket.
3. REMOVE BRAKE ACTUATOR ASSY
Remove the 2 nuts and brake actuator from the bracket.
4. INSTALL BRAKE ACTUATOR ASSY
Install the brake actuator to the bracket with the 2 nuts.
Torque:
DENSO made: 5.4 N·m (55 kgf·cm, 48 in.·lbf)
BOSCH made: 8.0 N·m (82 kgf·cm, 71 in.·lbf)
5. INSTALL BRAKE ACTUATOR WITH BRACKET
Install the brake actuator with the 3 nuts.
Torque: 19 N·m (194 kgf·cm, 14 ft·lbf)
Connect the brake actuator connector
Using SST, connect the each brake line to the correct position of brake actuator, as shown in the illustration.
SST 09023−00101
Torque: 15 N·m (155 kgf·cm, 11 ft·lbf)
