U026ELost Communication With Image Processing Sensor J
- Generic OBD-II code · Network
- How the car detects it
- U026E is not documented publicly by any manufacturer, so it is not known which camera letter J denotes. Exposed outside cameras show where such links are vulnerable. Prevost fits a side camera rear view system, eMirror, to H3-45 coaches from model year 2019 and to its X3 series. Its instructions for re-aiming these mirror-replacing cameras call for new single-use rubber washers on reassembly so the cover mount stays watertight (MI20-13, MI20-13A). Water in an exposed camera housing or its plug is a typical start of corrosion, intermittent contact and finally a silent sensor. Wherever sensor J sits, its loss blanks only the view or function it serves; the engine and its emissions are not involved, and no MIL is expected.
