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