C1421
| Either of the following is detected:
- With the IG1 terminal voltage between 9.5 and 17.4 V, the VCM terminal voltage is not between 4.4 and 5.6 V for 1.2 seconds or more.
- When the VCM terminal voltage is between 4.8 and 5.2 V, the PMC terminal voltage is not between 0.19 and 4.57 V for 1.2 seconds or more.
| Brake actuator assembly (Master cylinder pressure sensor)
|
C1421
| Detected only during Test Mode.
| Brake actuator assembly (Master cylinder pressure sensor)
|
C1423
| The PMC terminal voltage is less than 0.27 V for 5 seconds or more.
| Brake actuator assembly (Master cylinder pressure sensor)
|
C1424
| Any of the following is detected:
- Noise occurs in the PMC terminal 7 times or 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 (4.3 mph) or more, the PMC terminal voltage is between 0.86 and 1.0 V and does not change by at least 0.048 MPa for 60 seconds or more.
- At a vehicle speed of 7 km/h (4.3 mph) or more, the PMC terminal voltage is 1.0 V or more and does not change by at least 0.048 MPa for 30 seconds or more.
- At a vehicle speed of 7 km/h (4.3 mph) or more with the stop switch ON, a state in which the pressure sensor input value is sufficiently greater than the estimated master pressure continues for 1 second of 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.
