DTC U0100: Communication Stop from ECM to Distance Control ECU, VSC; DTC U0122: Lost Communication with Vehicle Dynamics Control Module; DTC U0123: Lost Communication with Yaw Rate Sensor Module; DTC U0126: Lost Communication with Steering Angle Sensor Module; DTC U1101: Lost Communication with Distance Control ECU: Description
This DTC is output when a communication malfunction occurs between the sensors and ECUs.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| U0100 | The vehicle speed is 40 km/h (25 mph) or more with the cruise control main switch on (vehicle-to-vehicle distance control mode) and communication from the ECM to the distance control ECU stops. |
|
| U0122 | The vehicle speed is 40 km/h (25 mph) or more with the cruise control main switch on (vehicle-to-vehicle distance control mode) and communication from the master cylinder solenoid (skid control ECU) to the ECM stops. |
|
| U0123 | While cruise control is in operation (vehicle-to-vehicle distance control mode), the data sent from the yaw rate sensor to the distance control ECU is abnormal. |
|
| U0126 | While cruise control is in operation (vehicle-to-vehicle distance control mode), the data sent from the steering angle sensor to the distance control ECU is abnormal. |
|
| U1101 | The vehicle speed is 40 km/h (25 mph) or more with the cruise control main switch on (vehicle-to-vehicle distance control mode) and communication from the distance control ECU to the ECM stops. |
