Kirk the AAM most likely failed.

the AAM is called the all activity module.

it is attached to the fuse box on the underside of it in the engine bay. and by fuse box I do not mean the box the fuse panel sits in but the fuse panel itself.

this is very common for the module to fail out of nowhere. it will have to be towed to a dealer as that is part of the immobilizer system so the dealer wont sell it over the counter.

sorry this happened but that is what you need to do to have it replaced.

hope this helps.

I was afraid of that.........whats the cost typically to replace the AAM module?
Customer reply replied 10 months ago
probably time to donate the car for a tax right off i guess............
Lol. It might be time , for the aam i am not 100% sure as I'm the fix it guy not the price it guy lol. Labor should not be more than 250$ or 2 hours of labor as it's super easy to diagnose and change . And any shop is going to want to charge diagnosis to double check which I always recommend . Aam might be 600$? But all shops will not charge the same markup
. Even dealers prices will be across the board it always depends on the local competition . Lou
