DTC C1A46: Yaw Rate Sensor [09/2015 - 08/2019]: Description

w/ VDIM:

The driving support ECU assembly receives yaw rate sensor signals from the yaw rate sensor assembly and skid control ECU (brake actuator assembly) via CAN communication. If the driving support ECU assembly receives yaw rate sensor malfunction signals from the yaw rate sensor assembly or skid control ECU (brake actuator assembly), DTC C1A46 is stored.

w/o VDIM:

The driving support ECU assembly receives yaw rate sensor signals from the airbag sensor assembly and skid control ECU (brake actuator assembly) via CAN communication. If the driving support ECU assembly receives yaw rate sensor malfunction signals from the airbag sensor assembly or skid control ECU (brake actuator assembly), DTC C1A46 is stored.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area
C1A46	Yaw Rate Sensor	While the vehicle is being driven at a speed of 5 km/h (4 mph) or more, the driving support ECU assembly receives a yaw rate sensor malfunction signals from yaw rate sensor for approximately 10 seconds. While the vehicle is being driven at a speed of 5 km/h (4 mph) or more, the driving support ECU assembly receives a yaw rate sensor zero point malfunction signals from skid control ECU (brake actuator assembly) for approximately 10 seconds.
