The Autopilot electronic control unit (ECU) detects a condition affecting radar ECU communication.
The Autopilot ECU sets this alert when the radar ECU reports missing Controller Area Network (CAN) messages or invalid values of CAN messages. Alert log signal data should provide information on the specific messages affected and condition(s) detected.
Depending on set condition, this alert should clear once the radar ECU's internal checks pass, indicating no further communication issues.
