Toyota Corolla Cross: Yaw Rate Sensor Circuit Voltage Out of Range (C00631C)

Toyota Corolla Cross (2022-2024) Service Manual / Brake / Brake Control / Dynamic Control Systems / Electronically Controlled Brake System (for Hev Model) / 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 sensors.
