U0269Lost Communication With Image Processing Sensor E

  • Generic OBD-II code · Network
How the car detects it
U0269 is a further member of GM's object detection group, kept by the active safety module first on 2015 Escalades with the Y66 driver assist package and, after a 2017 update, on many 2013–2018 Buick, Cadillac and Chevrolet models; GM does not publish which sensor letter E names. Its known trap is in the workshop: that bus uses its own circuits 3813 and 3811, which run to terminal 3 and terminal 11 of the DLC, which older scan tools seldom used. A worn MDI interface or cable on those pins can therefore produce a false U0269 and block any contact with the radars and front camera. GM's check is to try the same tool on a fault-free Y66 Escalade or with the EL-47955-1 loopback adapter before suspecting the sensor, (PIT5441B, PIT5441C). A genuine loss switches off the assistant that relies on sensor E.
