U0416 (68-2A) — Invalid Data Received From Vehicle Dynamics Control Module

System: Network Communication  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About U0416

U0416 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 U0416 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

The vehicle control modules communicate over the Controller Area Network (CAN) to exchange stability, traction, and braking control data. DTC U0416 sets when one or more modules receive CAN messages from the Vehicle Dynamics Control Module that contain invalid or implausible data. A failure type byte of 68 indicates a data plausibility or range fault, while a 2A qualifier denotes the message has stopped or become inconsistent during operation. This is typically caused by internal faults within the dynamics control module, an unstable power or ground supply, or CAN integrity issues. Because thi...
