1. CONNECT HAND±HELD TESTER:
(a) Connect the hand±held tester to the DLC3.
(b) Start the engine and run at idle.
(c) Select the ACTIVE TEST mode on the hand±held tester.
HINT:
Please refer to the hand±held tester operator's manual for fur-
ther details.
2. INSPECT ACTUATOR MOTOR OPERATION
(a) With the motor relay on, check the actuator motor operation noise.
(b) Turn the motor relay off.
(c) Depress the brake pedal and hold it for about 15 seconds. Check that the brake pedal cannot be de-
pressed.
(d) With the motor relay on, check that the pedal does not pulsate.
NOTICE:
Do not keep a motor relay tvrned on for more than 5 seconds continuously. When operating it contin-
uously, set an interval more than 20 seconds.
(e) Turn the motor relay off and release the brake pedal.
3. INSPECT RIGHT FRONT WHEEL OPERATION
NOTICE:
Never turn on a solenoid in a manner described below.
(a) With the brake pedal depressed, perform the following operations.
(b) Turn the SFRH and SFRR solenoid on simultaneously, and check that the pedal cannot be depressed.
NOTICE:
Do not keep a solenoids tvrned on for more than 5 seconds continuously. When operating it continu-
ously, set an interval more than 20 seconds.
(c) Turn the SFRH and SFRR solenoid off simultaneously, and check that the pedal can be depressed.
(d) Turn the motor relay on, and check that the pedal returns.
NOTICE:
Do not keep a motor relay tvrned on for more than 5 seconds continuously. When operating it contin-
uously, set an interval more than 20 seconds.
(e) Turn the motor relay off and release the brake pedal.
4. INSPECT OTHER WHEEL OPERATION
(a) Using the same procedure, check the solenoids of the other wheels.
