DTC P1615: Communication Error from Distance Control ECU to ECM: Description
The distance control ECU receives information about the area in front of the vehicle from the millimeter wave radar sensor assembly and then sends a brake control demand signal (deceleration demand) and diagnosis signals, such as millimeter wave radar sensor assembly grime signals or millimeter wave radar sensor assembly malfunction signals, to the ECM.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P1615 | While the dynamic radar cruise control is either preparing for operation or operating, if communication data from the distance control ECU is logically inconsistent for a certain amount of time, the ECM records this logical error code |
