About U1267

U1267 is a manufacturer-specific network communication diagnostic trouble code recorded for Jeep 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.

U1267 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

On this Chrysler group vehicle, the Powertrain Control Module or Transmission Control Module reads the selected gear range from the Electronic Shift Module, or ESM, over the CAN C or the Diagnostic Powertrain CAN bus. The ESM is the shift by wire shifter, since there is no mechanical linkage to the transmission. DTC U1267 sets when the receiving module is communicating with the ESM but the shift data it receives is missing, invalid, or implausible for a calibrated period, so it cannot be trusted to confirm the selected range. This differs from a total loss of communication, as messages are pre...
