The cost of fixing this fault code varies between $75 and $150 per hour, depending on the auto repair shop. Other factors that may influence the cost of fixing this fault code include the severity of the issue, the type of vehicle, and the location of the repair shop.

It is important to get an accurate diagnosis and estimate from a qualified mechanic before proceeding with any repairs.

The U1514 fault code is related to the Local Interconnect Network (LIN) Bus in automobiles. LIN Bus is a single wire transmission system with a speed of 10.417 Kbits. The LIN circuit is used to transmit serial data between a master control module and other LIN devices within a subsystem.

If the communication between any of the LIN devices is lost, the master control module will set a no communication code against the non-communicating LIN device. The U1514 code is set when the Headlamp Control ModuleHeadlamp Leveling Control Module loses communication with the Right Headlamp on the LIN Bus.
