This simply means that only one interface tool is needed for programming multiple vehicle make and models. All OBD-II compliant vehicles, must use one of the SAE specified protocols. The standard requests that all manufacturers use conventional methods of data communication, and allow independent repairers the ability to re-flash emission-related vehicle control units. J2534 is in fact, an interface standard designed by the Society of Automotive Engineers. You may have heard of a VCI referred to as a J2534 device. (Image courtesy of AutoMate) Software updates are “flashed” to a vehicle’s control module to correct shortfalls or improve product quality. The VCI acts as a translator or interpreter between the PC and the vehicle’s communication network, due to the different languages or programming code used. A Pass Thru device or VCI (Vehicle Communication Interface) is used for this data transfer. Pass-Thru is a method used to transfer data between a vehicle’s control module and a laptop or scan tool. With the introduction of “Pass Thru” flash programming, independent repairer’s now had a way of performing the same analysing, coding and reprograming tasks as an OEM, albeit with some limitations. There was also a distinct lack of training in this field outside of OEM dealerships, as access to OEM data and information had generally only been available to the dealer. These tools are very expensive and can often be hard to navigate. One reason is that each brand has their own specific diagnostic tool for analysing, coding and reprogramming. Reprogramming a vehicles control module (that is – updating its software, also commonly referred to as “flashing” the control module) has typically been left to an OEM dealer. The idea of a global car has many advantages, as the manufacturer can “tune” the vehicle to suit its geographical location. This process of common hardware and network architecture, has spread throughout most vehicle manufacturers and has given rise to the concept of the “Global Car.” Some vehicle manufactures use the same engine control module or hardware across their various models – they simply change the software to suit different operating conditions or engine and driveline configurations. (Image courtesy of AutoMate) Cars have become rolling computer networks with more lines of code than even the most sophisticated combat aircraft. Just like your home PC or laptop, the vehicle’s computers struggle with software issues, and often require updates to ensure they continue to meet emission regulations as well as addressing product quality concerns. If we strip away the mechanicals, the modern vehicle is essentially a rolling computer, using both hardware and software. ![]() These ECMs are connected via communication networks which allow for data transfer between each other. It’s a known fact that throughout the automotive industry, vehicles are becoming more and more complex, with almost every device in the modern car operated via an electronic control module. While this is a challenge for technicians now, imagine what interesting experiences still lay ahead of us. ![]() ![]() The rate at which technology is changing personal transportation accelerates every year. ![]()
