P0814Transmission Range Display Circuit

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
How the car detects it
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.
