Toyota Corolla Cross: Yaw Rate Sensor Circuit Intermittent (C00631F,C006396,C05201F,C11781F)
DESCRIPTION
The airbag ECU assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.
These DTCs are stored when the skid control ECU (brake actuator assembly) receives a malfunction signal from the yaw rate and acceleration sensor (airbag ECU assembly).

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 sensor and speed se
