DTC

C00631C

Yaw Rate Sensor Circuit Voltage Out of Range

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) calibrates the sensitivity of the yaw rate sensor (airbag sensor assembly) based on signals from the steering angle sensor and speed sensors.

DTC No.
