Diagnostic Trouble Code (DTC) Table

Note:
^ When beginning On Board Diagnostic (OBD) troubleshooting 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 (w/EDL) -J104- and printed-out on V.A.G 1551 or VAS 5051, are listed according to the 5 digit DTC code.
^ DTC code appears (in the "Rapid data transfer" mode) only on the print-out.
Example:
DTC code P code DTC type code
5 digit 5 digit 3 digit
18256 P 1848 035
^ The 5 digit P code which may appear next to the DTC code, is for use with the On Board Diagnosis (OBD) 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.
Refer to Electrical Wiring Diagrams, Troubleshooting & Component Locations
^ On completion of repairs always interrogate the DTC memory with V.A.G 1551 scan tool or the new tester VAS 5051 and erase.
^ Carry out road test exceeding 20 km/h (13 mph).
^ After the road test check DTC memory again.
