Halderman: Cars and light trucks and sport utility vehicles are equipped with On-Board Diagnosis-second generation, abbreviated OBD 2. The diagnosis is achieved by plugging in a scan tool to the data link connector (DLC), which is usually located under the dash on the driver side. Most code readers can retrieve and erase emission-related diagnostic trouble codes (DTCs) and some like the Zurich Zr4s can also read antilock brake (ABS) diagnostic trouble codes. OBD 2 has two computers. One is called global or generic and the other is enhanced or vehicle specific. The low-cost scan tools can only read global codes. To be able to read vehicle data and codes that are specific to that make, model and year, a factory or a factory-level aftermarket scan tool is required that cost many thousands of dollars.
Therefore, you can purchase any global scan tool — often called a code reader — at most automotive parts stores or online. And yes, they all work on Fords.
