DTC P1616: Communication Error from ECM to Distance Control ECU: Description
The ECM is the only component that has a function to store and output DTCs in the dynamic radar cruise control system. Therefore, if the driving support ECU detects a communication error from the ECM, it sends a malfunction signal back to the ECM.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| P1616 | While the vehicle speed is 50 km/h (30 mph) or more with the cruise control switch on, the ECM continuously receives a logical error signal from the driving support ECU for 0.15 seconds or more. |
