The ECM communicates with each sensor and ECU via CAN communication.
If any malfunction is detected in a CAN communication circuit, one or more CAN communication system DTCs are stored.

| U010487 | Lost Communication with Cruise Control Module Missing Message | When the ignition switch is ON and the dynamic radar cruise control system is operating, a communication malfunction between the millimeter wave radar sensor assembly and ECM is detected for approximately 1 second or more. | CAN communication system | Does not come on | Radar Cruise1 | SAE Code: U0104 |
| U012287 | Lost Communication with Vehicle Dynamics Control Module Missing Message | When the ignition switch is ON and the dynamic radar cruise control system is operating, a communication malfunction between the skid control ECU (brake actuator assembly) and ECM is detected for approximately 2.6 seconds or more. | CAN communication system | Does not come on | Radar Cruise1 | SAE Code: U0122 |
Clear the DTCs.
Make sure that the DTC detection conditions are met.
If the detection conditions are not met, the system cannot detect the malfunction.
