DTC C0063-2A: Yaw Rate Sensor Signal Stuck In Range; DTC C0520-1C: Multi-axis Acceleration Sensor Module "A" Circuit Voltage Out of Range; DTC C0520-2A: Multi-axis Acceleration Sensor Module "A" Signal Stuck In Range; DTC C0520-96: Multi-axis Acceleration Sensor Module "A" Component Internal Failure [12/2019 - ]: Description

The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.

These DTCs are stored when the skid control ECU (brake actuator assembly) receives an internal malfunction signal from the yaw rate and acceleration sensor (airbag sensor assembly).

The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor (airbag sensor assembly) via CAN communication.

HINT:

If a communication error with the yaw rate and acceleration sensor (airbag sensor assembly) is detected, DTCs U0125-87 and/or U0151-87 are stored.

If a DTC related to the CAN communication line is output, first troubleshoot the CAN communication line.

DTCs may be stored if either of the following occurs:

Yaw rate and acceleration sensor (airbag sensor assembly) installation abnormality.
Yaw rate and acceleration sensor (airbag sensor assembly) signal malfunction.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area
C0063-2A	Yaw Rate Sensor Signal Stuck In Range	A yaw rate sensor (airbag sensor assembly) stuck malfunction status continues.	Yaw rate sensor (airbag sensor assembly) installation Yaw rate sensor (airbag sensor assembly)
C0520-1C	Multi-axis Acceleration Sensor Module "A" Circuit Voltage Out of Range	At a vehicle speed of 30 km/h (19 mph) or more, the difference between the forward and backward G calculated from the acceleration sensor (airbag sensor assembly) value and that calculated from the vehicle speed sensor exceeds 0.35 G for 60 seconds or more.	Acceleration sensor (airbag sensor assembly) installation Acceleration sensor (airbag sensor assembly)
C0520-2A	Multi-axis Acceleration Sensor Module "A" Signal Stuck In Range	Any of the following is detected: The acceleration sensor (airbag sensor assembly) output value does not change 16 times or more as the vehicle speed drops from 30 km/h (19 mph) to 0 km/h (0 mph). A GL1 stuck malfunction status continues. A GL2 stuck malfunction status continues.	Acceleration sensor (airbag sensor assembly) installation Acceleration sensor (airbag sensor assembly)
C0520-96	Multi-axis Acceleration Sensor Module "A" Component Internal Failure	Either of the following is detected: A data malfunction signal is received from the acceleration sensor (airbag sensor assembly). Output values of GL1 and GL2 (front and rear, left and right) are outside permitted output range for 60 seconds or more.
