- The IG1 terminal voltage is between 9.5 V and 17.0 V.
- The VM/C1 terminal voltage is not within 4.4 V and 5.6 V.
Both of the following conditions continue for at least 1.2 seconds.
- The VM/C1 terminal voltage is between 4.4 V and 5.6 V.
- The PM/C1 terminal voltage is not within 0.19 V and 4.57 V.
| Master cylinder solenoid (Master cylinder pressure sensor, skid control ECU)

C1423
| Both of the following conditions continue for at least 5 seconds
- The stop light switch is off.
- The PM/C1 terminal voltage is below 0.3 V.
| Master cylinder solenoid (Master cylinder pressure sensor, skid control ECU)
|
C1424
| One of the following conditions is met:
- Noise occurs in the signal from the PM/C1 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 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.
- At a vehicle speed of 7 km/h (4 mph) or more, the PM/C1 terminal voltage is 1.0 V or more 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 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.

C1458
| One of the following conditions is met:
- When the vehicle speed is 10 km/h (6 mph) or more, noise occurs in the signal from the PCTRL terminal 7 times or more within 5 seconds.
- When the vehicle speed drops from 40 km/h (25 mph) to 0 km/h (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 change by at least 0.048 MPa for 60 seconds or more.
- At a vehicle speed of 7 km/h (4 mph) or more, the PCTRL terminal voltage is 1.0 V or higher and control 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 pressure control sensor input value is sufficiently greater than the estimated control 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.
