About U0159

U0159 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 U0159 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.

DTC U0159 is set when the receiving module does not detect valid CAN messages from the PACM within a calibrated time while the ignition is in the RUN position. Subcode 00 indicates a general communication failure, while subcode 2B denotes a missing message condition, confirming that the PACM is not transmitting required network data. With this fault the park...
