<p>This Master Thesis documents the development of an On Board Diagnosis (OBD-II) interface for remote diagnosis of vehicles. The Master Thesis is part of a project at the company Wayfinder Systems in Lund. </p><p>The purpose of this thesis was to design a scantool that communicates with a vehicle through its OBD-II port using relevant standards. </p><p>In order to make the OBD-II interface development easier, a car simulator was first built. Both the car simulator and the OBD-II interface were implemented using a linux computer running a C-program with serial communication with an external electrical interface. When the OBD-II interface was working satisfactory, tests were also made in a car – with good results. </p><p>The most difficult thing in the project was to meet the timing requirements in the standard specifications. </p><p>To be able to communicate with all cars that have an OBD-II port, further development of the OBD-II interface is required, because the OBD-II interface does not use all standards.</p>
