About U2010

U2010 is a generic (obd-ii standard) network communication diagnostic trouble code. 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 U2010 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

This DTC is a generic lost communication fault indicating that a module which does not communicate on the Standard Corporate Protocol, or SCP, network has failed to respond over the vehicle communication bus, typically CAN, LIN, or MOST. SCP is an older J1850 style network, so this code specifically flags a module living on one of the newer buses rather than the SCP bus, and a scan tool is usually needed to identify exactly which unit triggered it. The code sets when no valid communication is received from that module within a defined period. Symptoms depend entirely on which module is missing...
