DTC U0100: Lost Communication with ECM / PCM "A"; DTC U0100: Lost Communication with ECM / PCM "A"; 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
The ECM communicates with sensors and ECUs using CAN communication.
If communication malfunctions are detected, one or more CAN communication system DTCs will be stored.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| U0100 | While the dynamic radar cruise control is either preparing for operation or operating, if the ECM continuously receives a communication cut off signal from the distance control ECU for more than a specific amount of time, the ECM records this communication cut off code |
|
| U0100 | While the dynamic radar cruise control is either preparing for operation or operating, if the ECM continuously receives a communication cut off signal from the skid control ECU for a certain amount of time, the ECM records this communication cut off code |
|
| U0122 | While dynamic radar cruise control is either preparing for operation or operating, if communication data from the skid control ECU is invalid for a certain amount of time, the ECM records the communication cut off code |
|
| U0123 | While the dynamic radar cruise control is either preparing for operation or operating, the ECM continuously receives a yaw rate and acceleration sensor malfunction signal for a certain amount of time |
|
| U0126 | While the dynamic radar cruise control is either preparing for operation or operating, if the ECM continuously receives a steering sensor communication error signal for a certain amount of time, the distance control ECU sends a signal to the ECM to record this trouble code |
|
| U1101 | While the dynamic radar cruise control is either preparing for operation or operating, if communication data from the distance control ECU is invalid for a certain amount of time, The ECM records this communication cut off code |
