Connecting up vehicle diagnostic, testing and information system -VAS 5051A- and selecting functions |
t
| Vehicle power supply OK |
Note t
| The various functions of the vehicle diagnostic, testing and information system -VAS 5051A- are described in the system operating instructions. |
t
| The design and function of the vehicle diagnostic, testing and information system -VAS 5051A- are described in the → No.202. This also contains a range of examples illustrating correct system utilisation. |
t
| On this vehicle, the diagnostic connections of various control units (e.g. auxiliary heater, radio) are wired to a different diagnostic connector pin. To permit the exchange of data with these control units, the diagnostic wire between the vehicle and the vehicle diagnostic system (e.g. vehicle diagnostic, testing and information system -VAS 5051A- or vehicle diagnostic and service information system -VAS 5052-) must be fitted with a K-wire adapter -VAS 6017B- (or the K-wire adapter -VAS 6017A-) → Chapter and → Current flow diagrams, Electrical fault finding and Fitting locations. |
t
| On vehicles up to chassis number “399999” in Model Year 2005 (Saloon and Avant) and “012912” in Model Year 2005 (Cabrio) → Parts catalogue, self-diagnosis can also be performed using the fault reader -V.A.G 1551- or the vehicle system tester -V.A.G 1552- in mode “1” (rapid data transfer). The various functions are described in the relevant system operating instructions. On vehicles as of chassis number “400000” in Model Year 2005 (Saloon and Avant) and “012913” in Model Year 2005 (Cabrio), self-diagnosis can no longer be performed for all vehicle systems using the fault reader -V.A.G 1551- or the vehicle system tester -V.A.G 1552-. |
t
| In order to be able to perform self-diagnosis with the fault reader -V.A.G 1551- or the vehicle system tester -V.A.G 1552- on this vehicle, the program card in the fault reader -V.A.G 1551- must correspond to at least data level “No. 9” and in the vehicle system tester -V.A.G 1552- to at least data level “No. 6”. |
