U140E — Implausible Vehicle Configuration Data Received

System: Network Communication  |  Type: Manufacturer-Specific  |  Make: Chrysler

About U140E

U140E is a manufacturer-specific network communication diagnostic trouble code recorded for Chrysler 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.

U140E is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The receiving control module monitors vehicle configuration data transmitted over the CAN bus from other modules to ensure consistency with its internally stored configuration. DTC U140E is set when the module receives configuration or variant coding data that is implausible, contradictory, or does not match the expected vehicle build parameters for a calibrated period. The module compares the incoming data against the Vehicle Identification Number, option content, and stored variant codes to detect mismatches that can occur after module replacement, software updates, or partial reprogramming....
