BACKBACKTechnical Service InformationVOLKSWAGEN/AUDI 01M/01N/01P1996-2000 OBD-II CODE DEFINITIONSCOMPLAINT: When a VW/Audi vehicle is exhibiting a symptom or is in fail-safe, the technician, in manycases, is unable to communicate with the on-board diagnostics in order to retrieve the troublecodes.CAUSE:The lack of aftermarket equipment, previously unavailable to the technician, to allowaccess to vehicle on-board diagnostics such as, code retrieval, data lists and basic settingresets.CORRECTION: With the OBD-II mandate beginning in 1996, it is now possible to retrieve codes using theGeneric 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 anddata.There have also been recent developments which have made available, diagnostic toolswhich can communicate with VW/Audi vehicle modules, and also includes pre-OBD-IIdiagnostics for codes and data.Refer to Figures 1 and 2 for diagnostic connector locations in all Volkswagen/Audi modelsequipped 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 equippedwith gasoline engines.Refer to the code definition charts in Figures 13 thru 15 for ECM codes on vehicles equippedwith diesel engines.Refer to the code definition charts in Figures 16 and 17 for TCM codes.Copyright 2003 ATSGAUTOMATIC TRANSMISSION SERVICE GROUP03-27Page 1 of 18
