The Autopilot electronic control unit (ECU) detects a condition affecting radar ECU communication.
Potential Impact
Traffic-Aware Cruise Control (TACC) is unavailable. Other Autopilot features may be limited or unavailable.
Set condition
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.
