2013 genesis with immobilizer equipped.
The car died while driving. Restarted 10 minutes later but randomly died and had a host of other electrical gremlins like the cooling fan never shut off until it ran the battery dead. Towed to dealership. They had it for 3 weeks.
They claim it needs a new ECM but stated that it may not resolve the problem.
In an attempt to lower the repair costs, i have been researching online and have found some information. I am hoping someone can confirm if its legit.
Everything i have uncovered basically says that i can't swap the original ECM with a used ECM because this year/model, with an immobilizer, has an ECM that can only be encoded with one VIN number, one time, and its permanent so the used ECM wouldn't ever be able to work. Can anyone confirm this?
I also had a thought of getting a matched set, the main ECM and immobilizer module from a donor vehicle. Can anyone confirm if this will work?
i am trying to avoid the $2000 repair that may not work they say.
Any help would be greatly appreciated.
