U0565Invalid Data Received From Camera Module - Rear

Q: What does code U0565 mean?

Invalid Data Received From Camera Module - Rear. U0565 means the vehicle's main network gateway or control module received data from the rear camera module that it judged invalid or corrupted. The computer detected a message from the rear camera that failed its internal plausibility or checksum validation, so it flagged the camera as sending unusable information.

U0565 means the vehicle's main network gateway or control module received data from the rear camera module that it judged invalid or corrupted.

Symptoms you may notice

Rearview camera display shows a black screen, frozen image, or distorted picture
A warning message on the dash or infotainment screen indicating a camera system fault
Parking assist or rear cross-traffic features may be disabled or behave erratically
The infotainment system may reboot or show communication error messages
Often no symptoms besides the warning light, with the camera still working normally

Common causes, most likely first

Corroded or water-intruded connector at the rear camera module
Damaged or chafed wiring harness between the camera and the body control module
Failed rear camera module sending corrupted data frames
Low voltage or poor ground at the camera module causing intermittent data errors
Software glitch or outdated calibration in the camera or gateway module
Network bus fault, such as a shorted CAN (Controller Area Network) line, disrupting camera messages

How to diagnose and fix it

Inspect the rear camera connector and harness for corrosion, water damage, or loose pins, and clean or repair as needed
Check battery voltage and the camera module's ground connection to rule out low-voltage data corruption
Clear the code and test-drive to see if U0565 returns immediately or only under specific conditions
Use a scan tool to monitor live camera data and check for other communication codes on the same network
Perform a software update or recalibration of the camera module if the manufacturer has a known bulletin
Substitute a known-good rear camera module to confirm whether the original unit is faulty
If the camera is good, inspect the gateway or body control module connectors and network wiring for faults

Why the camera code may not mean a bad camera

A weak battery or poor ground can corrupt camera data frames without setting a low-voltage code, so always load-test the battery first.
Water intrusion at the rear camera connector is extremely common on hatchbacks and SUVs, and the pins can look clean until you separate the connector.
U0565 often appears alongside U-codes for other modules on the same bus, pointing to a shared network fault rather than the camera itself.
After replacing a camera module, some vehicles require a calibration or configuration procedure, and skipping it can set U0565 again.
A chafed harness behind the rear bumper or liftgate hinge can intermittently short the CAN lines, so wiggle-test the loom while watching live data.

Can I keep driving with U0565?

The vehicle remains safe to drive because the rear camera is a convenience feature, but you should not rely on it for reversing until the fault is repaired. Avoid reversing in tight spaces where the camera image is needed, and have the fault diagnosed soon to prevent water damage from spreading.
