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 U0155: Lost Communication with Instrument Panel Cluster (IPC) Control Module [03/2017 - 10/2020]: Description
These DTCs are stored when a communication malfunction occurs between ECUs that perform pre-collision system control.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| U0100 | Lost Communication with ECM / PCM "A" | When the vehicle is being driven at a speed of 5 km/h (4 mph) or more, a communication error between the ECM and millimeter wave radar sensor assembly is detected for approximately 5 seconds. |
|
| U0125 | Lost Communication with Yaw Rate Sensor Module | When the vehicle is being driven at a speed of 5 km/h (4 mph) or more, a communication error between the yaw rate sensor (airbag sensor assembly) and 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 sensor and 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 millimeter wave radar sensor assembly is detected for approximately 3 seconds. |
|
| U0155 | Lost Communication with Instrument Panel Cluster (IPC) Control Module | When the ignition switch is ON, a communication error between the combination meter assembly and millimeter wave radar sensor assembly is detected for approximately 8 seconds. |
