Alarm activation on vehicles without security system on Dodge Grand Caravan

Problem Description and Possible Solution
If the horn starts honking and the parking lights flash as if the alarm has been set off—and the vehicle is not equipped with the security system—reprogramming the front control module (FCM) with new software typically solves the problem.
