The airbag control module (ACM) in a 2002 Dodge Caravan is typically located
under the dashboard, on the passenger side. However, the exact location can vary slightly depending on trim level and specific options. It's often near the passenger's knees or further under the dash, requiring partial disassembly of the dash to access it.
To be absolutely certain, you should consult a repair manual specific to your 2002 Dodge Caravan. These manuals will have diagrams and detailed instructions showing the exact location. You can usually find these online (for a fee) or at auto parts stores. Attempting to locate it without a diagram could lead to unintended damage.
