Lexus ES: Yaw Rate Sensor Circuit Voltage Out of Range (C00631C)
DESCRIPTION
The airbag ECU assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.
The skid control ECU (brake actuator assembly) calibrates the sensitivity of the yaw rate sensor (airbag ECU assembly) based on signals from the steering angle sensor and speed sensors.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| C00631C | Yaw Rate Sensor Circuit Voltage Out of Range | The skid control ECU (brake actuator assembly) detects an abnormal yaw rate sensor (airbag ECU assembly) sensitivity during calculation. | Yaw rate sensor (airbag ECU assembly) |
CAUTION / NOTICE / HINT
NOTICE:
After replacing or reinstalling the yaw rate and acceleration sensor (airbag ECU assembly), perform acceleration sensor zero point calibration and store system information memorization after performing "Reset Memory".
