DTC C0063-1F: Yaw Rate Sensor Circuit Intermittent; DTC C0520-1F: Multi-axis Acceleration Sensor Module "A" Circuit Intermittent [09/2023 - ]: Description
WARNING: This page is about a different car, the 2024 Lexus TX 550h+ and 2024 Lexus TX 500h. 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.
The No. 2 skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor (airbag ECU assembly) via CAN communication.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | DTC Output from | Priority | Note |
|---|---|---|---|---|---|---|---|
| C0063-1F | Yaw Rate Sensor Circuit Intermittent | When voltage at terminal +BS is 9.5 to 17.4 V, sensor invalid information received from yaw rate sensor is ON continuously for 10 seconds or more. | Yaw rate sensor (airbag ECU assembly) | Does not come on | Brake/EPB | A | Output ECU: No. 2 skid control ECU (brake actuator assembly) |
| C0520-1F | Multi-axis Acceleration Sensor Module "A" Circuit Intermittent | When voltage at terminal +BS is 9.5 to 17.4 V, sensor invalid information received from acceleration sensor is ON continuously for 10 seconds or more. | Acceleration sensor (airbag ECU assembly) | Comes on | Brake/EPB | A |
