BACK BACK Technical Service Information VOLKSWAGEN/AUDI 01M/01N/01P 1996-2000 OBD-II CODE DEFINITIONS COMPLAINT: When a VW/Audi vehicle is exhibiting a symptom or is in fail-safe, the technician, in many cases, is unable to communicate with the on-board diagnostics in order to retrieve the trouble codes. CAUSE: The lack of aftermarket equipment, previously unavailable to the technician, to allow access to vehicle on-board diagnostics such as, code retrieval, data lists and basic setting resets. CORRECTION: With the OBD-II mandate beginning in 1996, it is now possible to retrieve codes using the Generic OBD-II part of your scan tool. This will also allow access to the "freeze frame" and "pending code" categories which are diagnostic aids to help the technician retrieve codes and data. There have also been recent developments which have made available, diagnostic tools which can communicate with VW/Audi vehicle modules, and also includes pre-OBD-II diagnostics for codes and data. Refer to Figures 1 and 2 for diagnostic connector locations in all Volkswagen/Audi models equipped with 096, 097, 098, 01M, 01N and 01P transmissions. Refer to the code definition charts in Figures 3 thru 12 for ECM codes on vehicles equipped with gasoline engines. Refer to the code definition charts in Figures 13 thru 15 for ECM codes on vehicles equipped with diesel engines. Refer to the code definition charts in Figures 16 and 17 for TCM codes.
