U0264 code meaning
Lost Communication With Camera Module - Rear
What U0264 means
The rear camera module supplies the reversing picture; whichever unit expects its messages stores U0264 when they stop, depending on the brand the radio, the body controller, the cluster or a central vision module. FCA uses it widely: a 2021 Ram 1500 logged it in the radio after connector XY552A worked loose once the tailgate had been off (S2108000050), and 2019–2020 Ram heavy-duty trucks with surround view set it in the CVPM next to B217A-92. On a 2019 Mazda3 a new rear camera plus old CMU software gave U0264:00 and a black center screen, so the CMU is updated first (09-021/19). Land Rover pointed it at the camera control module of its five-camera system (LTB00551NAS1); for the Transit, Ford calls a U0264 in a newly fitted BCM ignorable (SSM 47123). The reversing view is lost, driving is not.

Symptoms of U0264
- Black or blank screen when reverse is selected
- Camera system fault message, surround view button greyed out
- Code stored in radio, cluster or body controller, sometimes with blind spot faults
Common causes of U0264
- Most likelyCamera connector in tailgate or liftgate loose or not fully seated, often after body work
- PossiblePinched or chafed wire in the liftgate, camera fuse blown

What each part of U0264 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 64 | The exact fault in that area. |
What to do next
- Note U0264 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.
