U0268 code meaning
Lost Communication With Image Processing Sensor D
What U0268 means
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.
U0268 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor1 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0268
- 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
Common causes of U0268
- Most likelyFront fascia harness chafed at the right bumper bar, fuses blown
- PossibleConnector of sensor D loose or damaged after front-end repairs
- PossibleShort or open on the object detection bus
- Less likelySensor D internally faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0268 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 68 | The exact fault in that area. |
What to do next
- Note U0268 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0268
What does U0268 mean?
U0268 means "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. It is a generic code, so it means the same on every make.
Is it safe to drive with U0268?
U0268 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0268 fail an emissions test?
U0268 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U0268 to fix?
Difficulty: medium. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will U0268 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
