- INF Code: 171
- Sensor supply voltage (VCSK) is 4.7 V or less, or 5.4 V or more for 0.2 seconds or more.
- INF Code: 172
- Sensor output voltage 1 (SKS) is 6% or less, or 90% or more of sensor supply voltage (VCSK) for 0.2 seconds or more.
- INF Code: 173
- Sensor output voltage 2 (SKS2) is 6% or less, or 90% or more of sensor supply voltage (VCSK) for 0.2 seconds or more.
- INF Code: 174
- The stroke value converted from the sensor output 1 (SKS) fluctuates due to noise.
- INF Code: 175
- The stroke value converted from the sensor output 2 (SKS2) fluctuates due to noise.
- INF Code: 181
- A power source related malfunction other than INF codes 171, 172, 173, 174, 175, 182, or 183 occurs.
- INF Code: 182
- Difference between the output voltage of sensor 1 (SKS) and the output voltage of sensor 2 (SKS2) differs.
- INF Code: 183
- Compared to the output voltage of sensor 1 (SKS) and sensor 2 (SKS2), the output voltage of master cylinder pressure sensor 1 (PMC1) and master cylinder pressure sensor 2 (PMC2) are low.
