About U0182

U0182 is a generic (obd-ii standard) network communication diagnostic trouble code recorded for Land Rover 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 U0182 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 U0182 is set when one or more control modules on the CAN network detect a loss of communication with the Front Lighting Control Module for longer than the calibrated timeout period. The fault is logged when expected CAN messages from the lighting control module are missing, invalid, or not updating, indicating that the module is offline or unable to communicate reliably. This condition can affect the operation of front exterior lighting functions, including headlamps, daytime running lamps, and adaptive lighting features where fitted.
