| DTC Code | DTC Name |
|---|---|
| C1442 | Invalid Data Received from Deceleration Sensor |
| C1443 | Invalid Data Received from Yaw Rate Sensor |
DESCRIPTION
The skid control ECU (master cylinder solenoid) receives signals from the yaw rate and acceleration sensor (airbag sensor assembly) via the CAN communication system.
The yaw rate and acceleration sensor (airbag sensor assembly) has a built-in acceleration sensor.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| C1442 | An invalid data signal is transmitted continuously from the acceleration sensor for 10 seconds or more. | Yaw rate and acceleration sensor (Airbag sensor assembly) |
| C1443 | An invalid data signal is transmitted continuously from the yaw rate sensor for 10 seconds or more. | Yaw rate and acceleration sensor (Airbag sensor assembly) |
