Self-diagnosis of central locking system
Fault table for the central locking
Notes:
-
◆ The following table lists all the faults, with the corresponding 5-digit code numbers, that can be recognised by the central locking control unit and printed out by the V.A.G 1551.
-
◆ Fault codes appear only on print-out.
-
◆ Before replacing a component shown as faulty, check wiring and connections to component as well as earth connections according to current flow diagram.
-
◆ Once repairs have been completed, the fault memory is always to be interrogated again with fault reader V.A.G 1551 and erased. The vehicle is then to be relocked (with key or remote) and the fault memory is re-interrogated.
-
◆ All static and sporadic faults are stored in the fault memory:
When a fault occurs it is immediately identified as a static fault. If fault does not occur again it is registered as a sporadic fault. "/SP" appears on the right of the display.
-
◆ When ignition is switched on, all existing faults are automatically reclassified as sporadic faults and will only register as static faults if they still occur after testing.
-
◆ Sporadic faults which no longer occur after 50 opening cycles are erased automatically.
-
◆ The 3-digit fault type number appearing next to the fault code is a data code which can be ignored.
