Selectable Functions (Modes) Under Address Word 33, CARB/OBD II

Modes Under Address Word 33 OBD II (Generic Scan Tool):

Mode 1 - 7:

NOTE:
- Under Mode 1, individual measuring values can be displayed. Mode 1 is not recommended for use in a Volkswagen Service department, because these values can be displayed much more precisely using address word 01 and "Basic Setting" function 04 or "Read Measuring Value Block" function 08.
- Mode 2 shows the operating conditions under which the stored malfunctions were recognized.
- With Mode 3, DTC memory is checked-with Mode 4, DTC memory is erased.
- Mode 5 shows the statistical value of the oxygen sensors as mandated by law. As these values have no direct bearing on oxygen sensor diagnosis, Mode 5 is of no particular value in a Volkswagen Service department.
- Under Mode 6, values can be checked for components and systems that are not continuously monitored.
- With Mode 7 all malfunctions can be checked, even if they have not switched on the Malfunction Indicator Lamp (MIL) (if the MIL has not been switched on, there is no malfunction recognized under Mode 3).
