U026BLost Communication With Image Processing Sensor G
- Generic OBD-II code · Network
- How the car detects it
- Letter G, too, is visible only through GM: U026B appears in the active safety controller of Escalades from 2015 fitted with the Y66 assistance package, always grouped with U0265, U0268, U0269, U026A, U026C and U0075, and GM does not say which radar or camera G is. The grouping is itself the diagnostic hint. U0075 means that an entire communication bus has gone off, so if it shows up with several sensor codes, a shared cause such as supply, a short on the bus or harness damage is far more likely than a faulty sensor G. A lone U026B without its neighbours instead points to that module, its plug or its own feed. The earliest bulletins of 2015 and 2016 already list exactly this set (PIT5441, PIT5487A). The assistant using sensor G stays off; no MIL.
