U1400 DODGE Description
The purpose of the diagnostic is to monitor the Controller Area Network (CAN) BUS, the transmitted messages on the CAN BUS and the validity of the CAN signals.

The Diagnostic Trouble Code (DTC) sets when the Transmission Control Module (TCM) detects an incorrect CAN ID from the Powertrain Control Module (PCM).
