Code U1449 Chrysler Description

The U1449 Chrysler code indicates that an implausible Electronic Range Select (ERS) message has been received by the Transmission Control Module (TCM). The ERS is a feature that allows the driver to manually shift gears in an automatic transmission vehicle. When the TCM receives an ERS message that it deems to be implausible or incorrect, it triggers this diagnostic trouble code (DTC). This can lead to issues with the transmission's performance and overall drivability of the vehicle.
