Each malfunction is assigned a 5-digit Diagnostic Trouble Code (DTC). The DTC is located in the left column of the DTC
table. If you have switched the printer on by pressing the "PRINT" button, the VAG1551 scan tool (ST) prints the message
identifying the malfunction and the DTC. Otherwise, DTCs are not displayed by the VAG1551 scan tool.
The contents of DTC memory remain stored until memory is erased, page 01

.
Sporadically occurring malfunctions are identified via indication of "/SP" on the right-hand side of the display.
Static malfunctions that cannot be detected when the vehicle is stationary are also identified with "/SP" if the ignition has
been switched off and then on again.
The following DTC table includes all the DTCs that can be stored by the ABS control module -J104- and displayed and
printed out by the VAS5051 tester or VAG1551 scan tool. Malfunctions are listed by DTC number.
