Image processing sensor B has a documented owner at FCA, which reads U0266-00 as lost communication with the left camera of its 360-degree surround view. The central vision processing module (CVPM) takes each camera on its own colour-coded coaxial plug. On a 2022 Ram 1500 the driver mirror image stayed dark while every other camera worked, along with B23C6-92 and B23C6-1C; the guide plugs the tan driver lead into the brown passenger socket of the CVPM to separate camera from wiring, and the culprit was the door harness (S2208000115). On a 2019 Ram 1500 the left part of the top view dropped out now and then after a door repair; connector i6624C behind the door trim or XY451A at the kick panel had to be secured (S2108000266). Only the left image is missing, no MIL.

Likely causes

Coaxial camera lead in the driver door harness damaged or unplugged
Door or kick panel connector not secured after door repair
Camera plug loose at the central vision processing module
Left mirror camera internally faulty

Symptoms

  • Left side of the surround or top view black, other views normal
  • Fault appears intermittently, often after door work
  • Left camera performance code stored as well
