P0814 Transmission Range Display Circuit

P0814 concerns the drive or data circuit of the range display – the PRNDL or PRNDM display or lighting on the selector, sometimes in the instrument cluster. It is documented on the 2017–22 Jeep Compass with the nine-speed automatic: the electronic shift module stores P0814 with the MIL on, the selector lighting flickers or goes dark, and in a 2020 bulletin the lever could be moved out of park during cranking so that the engine stalled. The cause was software in the shift module, fixed by reflashing; a 2022 bulletin adds P081C. A wrong or missing range display matters for safety because the driver cannot reliably see P, R or N. No thresholds are published.

Likely causes

Shift module software (Jeep Compass)
Connector or wire to the selector display or cluster
Display LED or selector module faulty
Range sensor or transmission module delivering an invalid range

Symptoms

  • Range display on the selector flickers or stays dark
  • Check engine lamp (Jeep)
  • Lever can leave P during cranking, engine stalls (Jeep)
