WARNING: This page is about a different car, the 2021 Lexus ES 350, 2021 Lexus ES 250, 2020 Lexus ES 350, and 2019 Lexus ES 350. However, it is still accessible from the selected car via links, so may be relevant.
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 |
