The Engine Control Module (ECM), often called the Powertrain Control Module (PCM) in Chrysler vehicles, on a 2006 Dodge Grand Caravan is typically located
underneath the dashboard, on the driver's side. It's usually near the center, but its exact position can vary slightly depending on the specific trim level and options.
You'll likely need to remove some trim panels to access it. It's advisable to consult a repair manual specific to your 2006 Dodge Grand Caravan for the precise location and instructions on access. A Haynes or Chilton manual would be a good resource. Improperly accessing the module could damage it or other components.
