Ford ED-0032 Water Management Requirements

The “Ford ED-0032 Water management requirements” standard developed by Ford Motor Company describes the requirements and a test method to ensure that the electrical distribution system does not allow water to leak into the trunk or passenger compartments during normal operation of the vehicle.

In automotive electronics, body control module or body computer is a general concept for an electronic control unit responsible for monitoring and controlling various electronic accessories in the body of a vehicle. Generally, in a car, power windows, power mirrors, air conditioning, immobilizer system, central locking and similar equipment are controlled by the electronic control unit.

All circuits in vehicles are turned on and off via switches or relays (i.e. remote switches operated by electromagnets). Current flows from the battery to the powered component along a single cable and back to the battery through the metal body of the vehicle. The body is connected to the ground terminal of the battery with a thick cable.

If the wrong size wire is used or a wire is broken or disconnected, this can cause an accidental short circuit that bypasses the resistance of the component. The current in the wire can become dangerously high and melt the wire or cause a fire.

At this point, one of the functions of the electrical distribution system is to prevent water from leaking into the trunk or passenger compartments. Water leaking into a car can cause serious problems, so any leaks need to be addressed as soon as possible. Excessive moisture, as well as mold or mildew, can damage wiring, body parts or interior carpet and seats. Finding the leak is a challenging process.

In fact, today's modern vehicles have ingenious ways of dealing with water. Windows, doors and trunk lids use heavy-duty rubber seals to keep water out. The windshield has special sealants that not only help keep the windshield in place but also keep water out. Despite this, there are a few areas of the vehicle that may be suspicious.

Among the numerous testing, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides testing services within the scope of the "Ford ED-0032 Water management requirements" standard, with a trained and expert staff and advanced technological equipment.
