DTC P1615: Communication Error from Distance Control ECU to ECM [09/2014 - 11/2017]: Description
The driving support ECU assembly and ECM always communicate the general vehicle control and diagnosis data via CAN communication.
The driving support ECU assembly determines the distance, relative speed, and target deceleration speed based on the signals from the millimeter wave radar sensor assembly, and it sends a control demand signal to the ECM.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| P1615 | Communication Error from Distance Control ECU to ECM | While the dynamic radar cruise control system is either preparing for operation or operating, communication data from the driving support ECU assembly is logically inconsistent for a certain amount of time. |
