| U012287 | Lost Communication with Vehicle Dynamics Control Module Missing Message |
| U029387 | Lost Communication With Hybrid Powertrain Control Module Missing Message |
| U110487 | Lost Communication with Driving Support ECU Missing Message |
DESCRIPTION
The hybrid vehicle control ECU assembly 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.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| U012287 | Lost Communication with Vehicle Dynamics Control Module Missing Message | When the power switch is on (IG) and the dynamic radar cruise control system is operating, a communication error between the skid control ECU assembly and the hybrid vehicle control ECU assembly is detected for approximately 2.6 seconds or more. |
|
| U029387 | Lost Communication With Hybrid Powertrain Control Module Missing Message | While the vehicle speed is 5 km/h (3 mph) or more and the dynamic radar cruise control system is operating, the hybrid vehicle control ECU assembly continuously receives a communication cut-off signal from the skid control ECU assembly for approximately 1 second or more. |
|
| U110487 | Lost Communication with Driving Support ECU Missing Message | While the vehicle speed is 5 km/h (3 mph) or more and the dynamic radar cruise control system is operating, a communication error between the driving support ECU assembly and hybrid vehicle control ECU assembly is detected for 1 second or more. |

PROCEDURE
CHECK FOR DTCs (RADAR CRUISE 1)
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.
Check for DTCs.
