I took my Jeep Renegade to Jim Doran Jeep dealership in McMinnville because I was getting a Passive Entry System error message. Jeep passive entry system was working. Just an error message. Jim Doran diagnosed the problem for $65 and said they would have to download a software update that would cost me another 1/2 hours time and then would not guarantee the update that came out more than three years ago would fix the problem. I had already researched the issue online and the software update, a standard answer for jeep dealerships, does not fix the problem of the passive entry system error message. The I came across this forum which advised disconnecting the negative terminal on the battery and waiting one minute to reconnect. This immediately fixed the problem and the passive entry system error message has been fixed. Jeep dealership still claims this is impossible, even after I showed them the proof.
