| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| U012587 | Lost Communication with Multi-axis Acceleration Sensor Module Missing Message | While the vehicle is being driven at 5 km/h (3 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 or more 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 or more 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 booster with master cylinder assembly) and forward recognition camera for approximately 5 seconds or more. | CAN communication system |
| U013187 | Lost Communication with Power Steering Control Module Missing Message | 3 seconds or more after the ignition switch is turned to ON, while the lane control system is on, a communication error is detected between the power steering ECU (rack and pinion power steering gear 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 or more 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 |
| U029387 | Lost Communication with Hybrid/EV Powertrain Control Module Missing Message | 3 seconds or more after the ignition switch is turned to ON, while the vehicle is being driven at 5 km/h (3 mph) or more and the lane control system is on, a communication error is detected between the hybrid vehicle control ECU and forward recognition camera for approximately 5 seconds or more. | CAN communication system |
