DTC codes / U02xx · Lost communication with a control module / U026B
U026B is a generic network communication code indicating that a control module on the vehicle's Controller Area Network (CAN) bus has lost contact with the Image Processing Sensor G, which is typically a camera module used for driver assistance features. The module that monitors this sensor has stopped receiving its periodic CAN messages, so it sets this code and may disable the related driver-assist functions.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
