When a communication malfunction is detected between the forward recognition camera and an ECU or sensor, a DTC is stored.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| U010087 | Lost Communication with ECM/PCM "A" Missing Message | 3 seconds after the ignition switch is turned to ON, while the vehicle is being driven at 5 km/h (4 mph) or more and the lane control system is on, a communication error is detected between the ECM and forward recognition camera for approximately 5 seconds or more. | CAN communication system |
| U012587 | Lost Communication with Multi-axis Acceleration Sensor Module Missing Message | While the vehicle is being driven at 5 km/h (4 mph) or more and the lane control system is on, a communication error is detected between the yaw rate sensor (airbag ECU assembly) and forward recognition camera for approximately 5 seconds or more. | CAN communication system |
| U012687 | Lost Communication with Steering Angle Sensor Module Missing Message | 3 seconds after the ignition switch is turned to ON, while the lane control system is on, a communication error is detected between the steering sensor and forward recognition camera for approximately 5 seconds or more. | CAN communication system |
| U012987 | Lost Communication with Brake System Control Module Missing Message | 3 seconds after the ignition switch is turned to ON, while the lane control system is on, a communication error is detected between the skid control ECU (brake actuator assembly) and forward recognition camera for approximately 5 seconds or more. | CAN communication system |
| U015587 | Lost Communication with Instrument Panel Cluster (IPC) Control Module Missing Message | 3 seconds after the ignition switch is turned to ON, while the lane control system is on, a communication error is detected between the combination meter assembly and forward recognition camera for approximately 50 seconds or more. | CAN communication system |
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.
