On a 2002 Ford Expedition with 4-wheel ABS, the ABS control unit is typically located
under the driver's side dash, near the brake pedal. However, it's *not* always easily accessible and might be partially or completely hidden behind other components. You'll likely need to remove some trim panels to reach it.
It's a good idea to consult a repair manual specific to your year and model Expedition before attempting to locate or access it. These manuals provide diagrams and detailed instructions.
