DTC C0063-1F: Yaw Rate Sensor Circuit Intermittent; DTC C0520-1F: Multi-axis Acceleration Sensor Module "A" Circuit Intermittent [12/2019 - 10/2021]: Description

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 yaw rate sensor via CAN communication.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Note
