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.  

z

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 on 
the following pages according to the 5 digit DTC code.
