U0565 — Invalid Data Received From Camera Module Rear

Generic OBD-II · all makesNetwork / communication

Diagnostic trouble code U0565 indicates that the vehicle's control module (e.g., body control module or infotainment system) is receiving invalid or corrupted data from the rear camera module over the network. This typically means the camera module is not communicating properly, often due to a hardware fault, wiring issue, or software glitch.

Symptoms

What causes it — most likely first

1. Faulty rear camera module

The camera module itself has failed internally, often due to water ingress, physical damage, or electronic component failure. This is the most common cause.

2. Wiring or connector issues

Damaged, corroded, or loose wiring/connectors between the camera module and the vehicle's network can disrupt data transmission. Check for bent pins, broken wires, or moisture in connectors.

3. Software or calibration problem

After a battery disconnect, module replacement, or software update, the camera module may lose its calibration or require a software reflash to restore proper communication.

4. Low voltage or power supply fault

Insufficient voltage to the camera module (e.g., blown fuse, bad ground, or failing battery) can cause it to send invalid data or fail to communicate.

5. Other module interference

A fault in a related module (e.g., gateway module, body control module, or infotainment system) can corrupt network messages and trigger U0565 as a secondary code.

6. Engine control module (PCM/ECM) failure

Extremely rare; the PCM/ECM is almost never the cause of U0565. Only consider if multiple unrelated network codes are present and all other possibilities have been exhausted.

How it's diagnosed

  1. Connect a professional scan tool and read all stored codes, including pending and history codes. Note any other U-codes or B-codes that may indicate the root cause.
  2. Inspect the rear camera module and its wiring harness for visible damage, corrosion, or loose connections. Pay special attention to areas near the trunk lid or liftgate where wires flex.
  3. Check the camera module's power supply and ground circuits using a multimeter. Verify voltage (typically 5V or 12V depending on the system) and continuity to ground.
  4. If no physical issues are found, attempt to reflash or update the camera module software using manufacturer-specific diagnostic equipment.
  5. If the camera module is accessible, try swapping it with a known-good unit (if available) to see if the code clears. Otherwise, perform a network test to confirm the module is communicating.
  6. Only after ruling out all other causes, consider a fault in the receiving control module (e.g., BCM or infotainment module) or, very rarely, the PCM/ECM.

Frequently asked

Can I drive the vehicle with code U0565?

Yes, you can usually drive the vehicle, but the rearview camera and any related driver-assist features will likely be inoperative. The vehicle's safety systems (brakes, steering) are not affected.

Do I need to replace the rear camera module to fix U0565?

Not necessarily. While a faulty camera module is a common cause, wiring issues, poor connections, or software glitches can also trigger the code. A proper diagnosis is essential before replacing any parts.

Will disconnecting the battery clear the code?

Disconnecting the battery may temporarily clear the code, but if the underlying problem (e.g., a failed camera module) is still present, the code will return. It is not a permanent fix.

Is the engine computer (PCM/ECM) likely to be the problem?

No. For U0565, the PCM/ECM is almost never the cause. The code indicates a communication issue with the rear camera module, which is typically a separate module. Replacing the PCM is rarely necessary and should only be considered after all other possibilities have been thoroughly checked.
