DTC C1A46: Yaw Rate Sensor [03/2014 - ]: Description

The skid control ECU receives vehicle stability signals from the yaw rate sensor and sends the signals to the driving support ECU and ECM. If the skid control ECU detects that the yaw rate sensor is malfunctioning, the skid control ECU sends a malfunction signal to the driving support ECU, and the driving support ECU stores DTC C1A46. Also, when DTC C1A46 is stored, the skid control ECU stores DTC C1435 at the same time.

DTC No. DTC Detection Condition Trouble Area
