Performing self-diagnosis
Fault table
Notes:
-
◆ All the possible faults which are recognised by the automatic gearbox control unit -J217- and displayed on the V.A.G 1551 with the printer switched on when the fault memory is interrogated, are listed below grouped according to the fault code number.
-
◆ If fault occur only occasionally or if the fault memory was not erased after rectifying the faults, these faults will be displayed as "sporadic faults" for a stipulated period of time =>Gearbox control unit fault recognition, Page 01-3.
-
◆ If faulty components are detected during fault memory interrogation, additionally test wiring to components for short and open circuits according to the current flow diagram =>Golf 1992 ▸, Vento 1992 ▸Current flow diagram, Electrical fault finding and Fitting locations binder.
-
◆ The fault code is printed out in the "rapid data transfer" mode only when the printer of V.A.G 1551 is switched on.
Example: Fault code (5-position) 65535

No fault recognised! |
If "No fault recognised" appears after performing repairs, the self-diagnosis is completed.
In the event that the automatic gearbox does not operate properly despite self-diagnosis, carry out repairs as per fault finding programme.
