DTC U0100: Lost Communication with ECM / PCM "A"; DTC U0125: Lost Communication with Yaw Rate Sensor Module; DTC U0126: Lost Communication with Steering Angle Sensor Module; DTC U0129: Lost Communication with Brake System Control Module; DTC U1104: Lost Communication with Driving Support ECU [10/2016 - 09/2020]: Description
The driving support ECU assembly communicates 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.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| U0100 | Lost Communication with ECM / PCM "A" | 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 ECM and the driving support ECU assembly is detected for approximately 1 second or more. |
|
| 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 driving support ECU assembly is detected for approximately 1 second or more. |
|
| 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 sensor and the driving support ECU assembly is detected for approximately 1 second or more. |
|
| U0129 | Lost Communication with Brake System Control 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 skid control ECU (brake actuator assembly) and the driving support ECU assembly is detected for approximately 2.5 seconds or more. |
|
| U1104 | Lost Communication with Driving Support ECU | 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 driving support ECU assembly and the millimeter wave radar sensor assembly is detected for approximately 0.8 seconds or more. |
