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).
