The fault code U0256 is a communication error between the vehicle’s onboard computer and the fuel pump control module. The estimated repair time for this fault code is 1.0 hour.

The cost of fixing this fault code is dependent on the hourly rate charged by the auto repair shop. Most auto repair shops charge between $75 and $150 per hour.

Therefore, the cost of fixing the U0256 fault code can range from $75 to $150.

The U0256 code is a Controller Area Network (CAN) fault code.

CAN is a vehicle bus standard designed to interconnect automotive devices without a host computer.

The U0256 code sets when a periodic message from the Front Controls Interface Module ‘A’ has not been received.

This fault code indicates a lost communication with the Front Controls Interface Module ‘A’. The Front Controls Interface Module ‘A’ is responsible for sending messages to other modules in the vehicle. When this module fails to send messages, it can cause issues with other systems in the vehicle.

If you receive this fault code, it is important to have it diagnosed and repaired as soon as possible to prevent further issues.
