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 [10/2021 - 11/2023]: Description

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

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

These DTCs are stored when the No. 2 skid control ECU (brake actuator assembly) receives an internal malfunction signal from the yaw rate sensor.

The No. 2 skid control ECU (brake actuator assembly) receives signals from the yaw rate sensor via CAN communication.

HINT:

If there is a malfunction in the bus lines between the yaw rate sensor and the CAN communication system, DTC U0125-87 is output. When DTC U0125-87 is output together with C0063-2A, C0520-1C, C0520-2A and/or C0520-96, inspect and repair the trouble areas indicated by U0125-87 first.

DTCs may be stored if either of the following occurs:

Yaw rate sensor installation abnormality.
Yaw rate sensor signal malfunction.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Note
C0063-2A	Yaw Rate Sensor Signal Stuck In Range	A yaw rate sensor stuck malfunction status continues.	Yaw rate sensor installation Yaw rate sensor	Does not come on	Output ECU: No. 2 skid control ECU (brake actuator 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 value and that calculated from the vehicle speed sensor exceeds 0.35 G for 60 seconds or more.	Acceleration sensor (yaw rate sensor) installation Acceleration sensor (yaw rate sensor)	Comes on	SAE Code: C051C (Case 3) Output ECU: No. 2 skid control ECU (brake actuator assembly)
C0520-2A	Multi-axis Acceleration Sensor Module "A" Signal Stuck In Range	Any of the following is detected: The acceleration sensor 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 (yaw rate sensor) installation Acceleration sensor (yaw rate sensor)	Comes on	SAE Code: C051C (Case 1 and 2) Output ECU: No. 2 skid control ECU (brake actuator assembly)
C0520-96	Multi-axis Acceleration Sensor Module "A" Component Internal Failure	Either of the following is detected: A signal indicating an acceleration sensor internal malfunction is received Output values of GL1 and GL2 (front and rear, left and right) are outside permitted output range for 60 seconds or more.	Acceleration sensor (yaw rate sensor) installation Acceleration sensor (yaw rate sensor)	Comes on	SAE Code: C0520 (Case 1 and 2) Output ECU: No. 2 skid control ECU (brake actuator assembly)
