Motor Relay |
(b) Turn the motor relay on and check for actuator motor operation sounds.
NOTICE:
Do not keep the motor relay on continuously for more than 5 seconds. If it needs to be operated repeatedly, wait an interval of more than 20 seconds between operations.
(c) Turn the motor relay off.
(d) Fully depress the brake pedal and hold it for approximately 15 seconds. Check that the initial brake pedal depth is maintained for the entire 15 seconds.
(e) Turn the motor relay on and check that the brake pedal does not pulsate.
NOTICE:
Do not keep the motor relay on continuously for more than 5 seconds. If it needs to be operated repeatedly, wait an interval of more than 20 seconds between operations.
