Parts + labor, varies by vehicle and location
The body control module or driver assistance system has lost communication with the Rear Camera Module. This affects the backup camera display and potentially parking assistance features.
The most common cause of U0264 (Lost Communication With Camera Module Rear) is: Failed rear camera module electronics or image sensor
Typical repair costs for U0264 range from $200 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Moderate safety concern. Loss of rear camera functionality reduces rearward visibility when reversing, increasing risk of backing collisions. Use mirrors and turn head to check blind spots.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0264 to identify the root cause.
