VOLKSWAGEN/AUDI 01M/01N/01P

1996-2000 OBD-II CODE DEFINITIONS

COMPLAINT:

CAUSE:

CORRECTION:

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 codes.

The lack of aftermarket equipment, previously available to the technician, to  allow access 
to vehicle on-board diagnostics such as, code retrieval, data lists and basic setting resets.

With the OBD-II mandate beginning in 1996, it is 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 which include pre-OBD-II 
diagnostics for codes and data.

Use the illustrations in figures 1 and 2 for diagnostic connector locations in all 
Volkswagen/Audi models equipped with 096, 097, 098, 01M, 01N and 01P   transmissions.

Use the code definition charts in figures 3 to 12 for ECM codes for gasoline engine equipped 
vehicles.

Use the code definition charts in figures 13 to 15 for ECM codes for diesel engine equipped 
vehicles.

Use the code definition charts in figures 16 and 17 for TCM codes.
