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 |
|---|---|---|---|
| U0100-87 | Lost Communication with ECM/PCM "A" Missing Message | 2 seconds after the engine switch is turned on (IG), 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 |
| U0125-87 | 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 |
| U0126-87 | Lost Communication with Steering Angle Sensor Module Missing Message | 2 seconds after the engine switch is turned on (IG), 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 |
| U0129-87 | Lost Communication with Brake System Control Module Missing Message | 2 seconds after the engine switch is turned on (IG), 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 |
| U0131-87 | Lost Communication with Power Steering Control Module Missing Message | 2 seconds after the engine switch is turned on (IG), 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 |
| U0155-87 | Lost Communication with Instrument Panel Cluster (IPC) Control Module Missing Message | 2 seconds after the engine switch is turned on (IG), 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 |
