DESCRIPTION
The millimeter wave radar sensor assembly and ECM communicate with each sensor and ECU via CAN communication.
If any malfunction is detected in a CAN communication circuit, one or more CAN communication system DTCs are stored.

Does not come on |
U0125 |
Lost Communication with Yaw Rate Sensor Module |
While the vehicle speed is 36 km/h (22 mph) or more and the dynamic radar cruise control system is operating, a communication error between the yaw rate sensor and the millimeter wave radar sensor assembly is detected for approximately 1 second or more. |
|
Does not come on |
U0126 |
Lost Communication with Steering Angle Sensor Module |
While the vehicle speed is 36 km/h (22 mph) or more and the dynamic radar cruise control system is operating, a communication error between the steering angle sensor and the millimeter wave radar sensor assembly is detected for approximately 1 second or more. |
