DTC C1247/47: Stroke Sensor Malfunction; DTC C1346/71: Stroke Sensor Zero Point Learning Malfunction (Test Mode DTC); DTC C1392/48: Stroke Sensor Zero Point Calibration Undone: Description
The stroke sensor inputs the pedal stroke information into the skid control ECU.
DTC C1346/71 will be cleared when the brake pedal stroke sensor sends a stroke sensor signal or when Test Mode ends. DTC C1346/71 is output only in Test Mode.
| DTC Code | INF Code | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| C1247/47 | 171 | Sensor output voltage (SKS or SKS2) is less than 0.15 V or 4.85 V or more, or sensor power source voltage (VCSK) is 3.6 V or less or 4.95 V or more for at least 0.2 seconds. |
|
| ↑ | 172 | Ratio of sensor output voltage 1 (SKS) to sensor power source voltage (VCSK) is less than 3% or 97% or more for at least 0.2 seconds. |
|
| ↑ | 173 | Ratio of sensor output voltage 2 (SKS2) to sensor power source voltage (VCSK) is less than 3% or 97% or more for at least 0.2 seconds. | ↑ |
| ↑ | 174 | The stroke value converted from sensor output 1 (SKS1) fluctuates due to noise. | ↑ |
| ↑ | 175 | The stroke value converted from sensor output 2 (SKS2) fluctuates due to noise. | ↑ |
| ↑ | 176 | Zero point stored value (related to power source voltage) of sensor output 1 (SKS1) is not between 0.15 V and 2.3 V. |
|
| ↑ | 177 | Zero point stored value (related to power source voltage) of sensor output 2 (SKS2) is not between 2.42 V and 4.85 V. | ↑ |
| ↑ | 179 | Difference between sensor output 1 (SKS1) and sensor output 2 (SKS2) is excessively large for at least 0.2 seconds. |
|
| ↑ | 181 | Information code 171, 172 173, 174, 175, 176, 177 or 179 is generated. | ↑ |
| C1392/48 | - | Zero point calibration of stroke sensor is unfinished. |
|
| C1346/71 | - | Detected only during Test Mode. |
