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 in the following information 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

Refer to 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).
• After the road test check DTC memory again.

V.A.G 1551 print-out	Possible cause	Repair
No DTC recognized	If "No DTC recognized" appears after carrying out repairs, On Board Diagnostic (OBD) is ended. If, despite "No DTC recognized" appearing in the display, the ABS system does not function properly, then proceed as follows: 1. Carry out road test exceeding 20 km/h (13 mph), 2. Again check DTC memory, if there is still no DTC stored, 3. Continue troubleshooting without OBD and work through the complete Electrical check. Refer to ABS, ABS/EDL and ABS/EDL/ASR ITT Mark 20 IE, electrical check  .
