Periodically my car will have a DTC of P1818. I'm not having any issues with the car actually being in reverse when it's in park or rolling away. The only issue I'm having is with the doors not automatically locking/unlocking when I put the car in park/reverse. Also, on the dash where it highlights whether you're in park, reverse, neutral, etc, it's not lit up. I recently had a new TCM put in my car and the dealership programmed it. Could this be an issue with the programming? I know there was a TSB about it but my car wouldn't qualify for it. When I clear the code, it goes back to normal, then randomly stops working.
have the same problem?
