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.
