DTC C1A46: Yaw Rate Sensor [09/2015 - ]: Description

The skid control ECU assembly receives vehicle stability signals from the yaw rate sensor and sends the signals to the driving support ECU assembly and ECM. If the skid control ECU assembly detects that the yaw rate sensor is malfunctioning, the skid control ECU assembly sends a malfunction signal to the driving support ECU assembly and outputs DTC C1A46. Also, when DTC C1A46 is output, the skid control ECU assembly outputs DTC C1234 at the same time.

When DTC C1A46 is detected, DTC C1234 is also output from the "ABS/VSC/TRAC".
