Roadi RDT55 Diagnostic Trouble Code Reader for Vol

Advanced Handheld Automotive Diagnostics for VW and Audi
Beginning in the 1980s new vehicles began to be wired with a variety of computerized diagnostic systems designed to improve efficiencies, simplify troubleshooting and minimize the need for repairs. These systems produce indicators known as diagnostic trouble codes (DTC) internally, usually indicating something out of the ordinary by illuminating the “check engine”/malfunction indicator light (MIL) on the dashboard of your car. In the 1990s these systems, codes and the hardware connectors used to access them were standardized in North America as OBD (onboard diagnostics) and later OBD-II. Europe uses the equivalent EOBD, but Volkswagen and Audi vehicles also use another diagnostic standard system, VAG. Unofficially this acronym can be taken to stand for “Volkswagen Audi Group.”

The Roadi RDT55 VW/AUDI Code Scanner is specially designed to work with most Volkswagen and Audis sold worldwide of 1990 or newer models. If a VW/AUDI has a 16 pin OBD-II style Data Link Connector (DTC), the scanner tool will certainly work. If it has an old-style 2×2 Data Link Connector (DTC), then it depends on whether there are 4 or 3 wires connecting to the pins. If there are 4 wires, each connecting a pin, then it will work. If there are only 3 wires leaving one pin disconnected then it will not work. For VW/AUDI with old-style 2×2 Data Link Connector (DTC), you need to have a 2×2 cabling adapter which is not included in this product package. Once a viable configuration is found, to use while the engine is off simply plug the RDT55 code reader cable connector into the corresponding data port in your vehicle, usually located near the dashboard or gearshift. Then switch the ignition on and scroll to the right menu option users can gain access to generic and vehicle specific VAG and OBD-II codes related primarily to the engine, transmission, airbag and ABS systems that trigger MIL events. Definitions for the DTCs will be displayed on-screen and can be found in your manual or via the CD definitions lists in on the CD included. The RDT55 reads trouble codes for most Volkswagen’s 78 systems, views live engine data and supports all AW and VW OBD2/EOBD protocols, including the newly released controller area network (CAN) protocol, allowing users to keep up with the latest development in automotive diagnostic scanning. Additional features include a USB cable for updating the RDT55s definitions list and software and a nylon carrying case. The RDT55 can view live engine data, providing the ability to troubleshoot issues more thoroughly by viewing the data that causes DTCs to be generated.
