About U2514

U2514 is a generic (obd-ii standard) network communication diagnostic trouble code recorded for Ford vehicles. It belongs to the U-prefix family of codes, which covers inter-module network communication (CAN, LIN, FlexRay, or similar) faults.

Scanning & clearing: Network (U) codes report communication faults between modules. When diagnosing U-codes, checking the vehicle's CAN bus integrity, supply/ground at each module, and reading all modules for related faults is usually the first step.

Because U2514 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

DTC U2514 is a manufacturer specific network code set when a control module does not receive a valid vehicle speed signal over the CAN bus, or receives speed data that is implausible or inconsistent with other operating inputs. The module monitors the vehicle speed message from the ABS or powertrain module and runs plausibility checks, logging this fault when the signal is missing, frozen, or outside expected limits. The fault therefore covers two cases, a speed message that is absent and one that is present but incorrect, and the diagnosis must distinguish between them. Symptoms can include a...
