more within 5 seconds
- When the vehicle speed drops from 40 km/h (25 mph) to 10 km/h
(6 mph), the master cylinder pressure does not change by at least
0.048 MPa.
- At a vehicle speed of 7 km/h (4 mph) or more, the PM/C1 terminal
voltage is between 0.86 and 1.0 V and master cylinder pressure does
not change by at least 0.048 MPa for 60 seconds or more.

voltage is 1.0 V or higher and master cylinder pressure does not
change by at least 0.048 MPa for 30 seconds or more.
- At a vehicle speed of 7 km/h (4 mph) or more with the stop light
switch ON, a state in which the master cylinder pressure sensor
input value is sufficiently greater than the estimated master pressure
continues for 1 second or more and this state occurs 5 or more times
each time the ignition switch is turned to ON, and this occurs 8
or more times consecutively.

(0 mph), the control pressure does not change by at least 0.048
MPa, and this occurs 5 times.
- At a vehicle speed of 7 km/h (4 mph) or more, the PCTRL terminal
voltage is between 0.86 and 1.0 V and control pressure does not
