U0268 Lost Communication With Image Processing Sensor D

GM files U0268 among the codes of its object detection bus, a separate network that links the active safety module with the radars and the front camera on Cadillac Escalades of model years 2015–2020 equipped with driver assistance. Which sensor letter D denotes is not stated in the bulletins. The best documented cause is mechanical: the front fascia harness can rub through where the right side of the bumper bar ends and blow fuses F10DL, F19DR, F43UA or F46DR, so front parking, turn, daytime and cornering lamps fail while U0268 is stored along with U0265, U0269, U026A–U026C and U0075. GM has the fascia removed, the wiring repaired, and the harness rerouted behind the bar and tied to the fascia (PIT5487B, PIT5487E). Surround view, park assist and adaptive cruise report service messages; no MIL.

Likely causes

Front fascia harness chafed at the right bumper bar, fuses blown
Connector of sensor D loose or damaged after front-end repairs
Short or open on the object detection bus
Sensor D internally faulty

Symptoms

  • Service messages for surround camera, park assist and adaptive cruise
  • Front parking, turn, daytime or cornering lamps dead, turn signal flashes fast
  • Several radar and camera U-codes stored at once
