DTC C0063-28: Yaw Rate Sensor Signal Bias Level Out of Range / Zero Adjustment Failure; DTC C0063-96: Yaw Rate Sensor Component Internal Failure [11/2021 - 10/2023]: Description

The yaw rate sensor has a built-in airbag ECU assembly.

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

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Note
C0063-28 Yaw Rate Sensor Signal Bias Level Out of Range / Zero Adjustment Failure With the vehicle stationary, the yaw rate sensor output value is not 0°/s. Yaw rate sensor (airbag ECU assembly) Does not come on Output ECU: No. 2 skid control ECU (brake actuator assembly)
C0063-96 Yaw Rate Sensor Component Internal Failure With the +BS terminal voltage between 9.5 and 17.4 V, a data malfunction signal is received from a yaw rate sensor. Yaw rate sensor (airbag ECU assembly) Does not come on Output ECU: No. 2 skid control ECU (brake actuator assembly)
