U0267 Lost Communication With Image Processing Sensor C

No vehicle maker documents U0267 in public service material, so the camera behind letter C remains unknown, and letters are assigned differently from brand to brand. What can break is clear from the hardware. Cameras usually send their data over a coaxial or twisted-pair serial link, and the receiving deserializer reports a lock status for each port; Texas Instruments' DS90UB954 even allows configuration of a camera only while its link is locked. A Chalmers thesis built on a parking camera rig ranks a cut or shorted cable and the loss of link lock after too many bit errors as the critical faults. Either one leaves sensor C silent for the module that polls it. The function fed by sensor C stops; the MIL stays off.

Likely causes

Camera link cable open or shorted, connector corroded
Link loses lock due to bit errors from a degraded cable or interference
Sensor C without supply, for example power over the coaxial line missing
Sensor C internally faulty

Symptoms

  • One camera view or camera-based assistant unavailable
  • Service message for the camera or driver assistance
