Code U1267 Jeep Description

The U1267 diagnostic trouble code (DTC) for Jeep vehicles indicates that there is no valid data being received from the Electronic Shift Module (ESM) on the Controller Area Network (CAN) bus. The ESM is responsible for controlling the shifting of the transmission in the vehicle. When the Engine Control Module (ECM) or Transmission Control Module (TCM) is unable to communicate with the ESM, it can lead to various issues with the transmission system. This lack of communication can result in the vehicle not shifting properly, erratic shifting behavior, or even the transmission going into a fail-safe mode where it may only operate in one gear.
