Diagnostic Trouble Code (DTC) table
Note on DTC table:
When beginning OBD of the vehicle control modules, always start with function
"Automatic test sequence" by pressing keys 0 and 0 because the control modules
are interconnected with a data bus wire. This checks the DTC memories of the
control modules in the vehicle.
All the possible DTCs which can be recognized by the ABS control module -J104-
and printed-out on V.A.G 1551 or VAS 5051, are listed on the following pages
according to the 5-digit DTC.
DTC appears (in the "Rapid data transfer" mode) only on the print-out.
Example:
DTC P code DTC type code
5-digit 5-digit 3-digit
18256 P1848 035
The 5-digit P code which may appear next to the DTC, is for use with the On Board
Diagnostic (OBD) II and may be disregarded.
The 3-digit DTC type code is a data code and may be disregarded, but the DTC type
text is of use.
Before replacing components indicated as being faulty, check all the appropriate
connectors, wiring and Ground connections using the wiring diagram
Electrical Wiring Diagrams, Troubleshooting & Component Locations binder
On completion of repairs always check the DTC memory with V.A.G 1551 Scan Too.
or the tester VAS 5051 and erase.
Carry out road test exceeding 20 km/h (13 mph).
