DTC C0063-1F: Yaw Rate Sensor Circuit Intermittent; DTC C0520-1F: Multi-axis Acceleration Sensor Module "A" Circuit Intermittent [10/2022 - ]: Description
WARNING: This page is about a different car, the 2025 Lexus RX 350, 2024 Lexus RX 350, and 2023 Lexus RX 350. However, it is still accessible from the selected car via links, so may be relevant.
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) receives signals from the yaw rate and acceleration sensor (airbag ECU assembly) via CAN communication.
