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 U023A: Lost Communication with Front Camera Module [02/2017 - 08/2020]: Description
These DTCs are stored when a communication malfunction occurs between ECUs that perform pre-collision control.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| U0100 | Lost Communication with ECM / PCM "A" | When driving the vehicle at a speed of 5 km/h (4 mph) or more, a communication error between the ECM and the millimeter wave radar sensor assembly is detected for approximately 5 seconds. |
|
| U0125 | Lost Communication with Yaw Rate Sensor Module | When driving the vehicle at a speed of 5 km/h (4 mph) or more, a communication error between the yaw rate and acceleration sensor (airbag sensor assembly) and the millimeter wave radar sensor assembly is detected for approximately 1 second. |
|
| U0126 | Lost Communication with Steering Angle Sensor Module | When the ignition switch is ON, a communication error between the steering angle sensor (spiral cable with sensor sub-assembly) and the millimeter wave radar sensor assembly is detected for approximately 4 seconds. |
|
| U0129 | Lost Communication with Brake System Control Module | When the ignition switch is ON, a communication error between the skid control ECU (brake actuator assembly) and the millimeter wave radar sensor assembly is detected for approximately 3 seconds. |
|
| U023A | Lost Communication with Front Camera Module | After the ignition switch is turned ON, a communication malfunction occurs between the millimeter wave radar sensor assembly and forward recognition camera. |
