DESCRIPTION
The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.
The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor (airbag sensor assembly) via CAN communication.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | DTC Output from |
---|---|---|---|---|
C00631F | Yaw Rate Sensor Circuit Intermittent | When voltage at terminal +BS is 9.5 to 17.4 V, sensor invalid information received from yaw rate sensor is ON continuously for 10 seconds or more. | Yaw rate sensor (airbag sensor assembly) | Brake |
C05201F | Multi-axis Acceleration Sensor Module "A" Circuit Intermittent | When voltage at terminal +BS is 9.5 to 17.4 V, sensor invalid information received from acceleration sensor is ON continuously for 10 seconds or more. | Acceleration sensor (airbag sensor assembly) | Brake |
CAUTION / NOTICE / HINT
NOTICE:
If the yaw rate and acceleration sensor (airbag sensor assembly) was replaced or reinstalled, perform "Calibration".
