DTC C1A46: Yaw Rate Sensor [04/2013 - 10/2016]: Description

If the brake actuator assembly (skid control ECU) detects that the yaw rate sensor is malfunctioning, the brake actuator assembly (skid control ECU) sends a malfunction signal to the driving support ECU assembly, and the driving support ECU assembly stores this DTC.
