On-vehicle inspection

1. 1
   Connect intelligent tester
2. 2
   Connect the intelligent tester to the dlc3.
3. 3
   Start the engine and idle it.
4. 4
   Select the active test mode on the intelligent tester.

Please refer to the intelligent tester operator's manual for further details.

2. Check actuator motor operation

Do not keep a motor relay on for more than 5 seconds. When operating it consecutively, wait 20 seconds between each operation.

1. 1
   Turn the motor relay on and check the actuator motor operation noise.
2. 2
   Turn the motor relay off.
3. 3
   Fully depress the brake pedal and hold it for approximately 15 seconds. Check that the pedal's initial depth is maintained for the entire 15 seconds.
4. 4
   Turn the motor relay on and check that the pedal does not pulsate.
5. 5
   Turn the motor relay off and release the pedal.
6. 6
   Check brake actuator solenoid (for front right wheel)

• Be sure to follow the procedures below when turning on a solenoid.
• Do not keep a solenoid on for more than 10 seconds. When operating it consecutively, wait 20 seconds between each operation.
• Do not keep a motor relay on for more than 5 seconds. When operating it consecutively, wait 20 seconds between each operation.

1. 1
   With the pedal depressed as much as possible, perform the following operations.
2. 2
   Turn the sfrh and sfrr solenoids on simultaneously, and check that the pedal cannot be depressed further.
3. 3
   Turn the sfrh and sfrr solenoids off simultaneously, and check that the pedal can be depressed further.
4. 4
   Turn the motor relay on. Check that the pedal returns to the "depressed as much as possible" position.
5. 5
   Turn the motor relay off and release the pedal.
6. 6
   Check brake actuator solenoid (for front left wheel)
7. 7
   Use the same procedures described for the front right wheel to check the solenoids of the front left wheel.

Front left wheel: sflh, sflr

1. 1
   Check brake actuator solenoid (for rear right wheel)
2. 2
   Use the same procedures described for the front right wheel to check the solenoids of the rear right wheel.

Hint: rear right wheel: srrh, srrr

1. 1
   Check brake actuator solenoid (for rear left wheel)
2. 2
   Use the same procedures described for the front right wheel to check the solenoids of the rear left wheel.

Hint: rear left wheel: srlh, srlr

1. 1
   Check and clear dtc
2. 2
   Check and clear the dtc (see page bc-47).
