WARNING: This page is about a different variant/trim than selected.

The yaw rate sensor has a built-in acceleration sensor.

The No. 2 skid control ECU (brake actuator assembly) receives signals from the hybrid vehicle control ECU, steering angle sensor, certification ECU (smart key ECU assembly), inverter with converter assembly, No. 1 skid control ECU (brake booster with master cylinder assembly), airbag sensor assembly, yaw rate sensor and ECM via CAN communication.
