Fault table for interior monitoring

Notes:

  • ◆ The following table lists all faults that can be recognised by the transmit/receive control module for interior monitoring and printed out using V.A.G 1551. The faults are listed in order according to their 5-digit code numbers.
  • ◆ Fault codes appear only on print-out.
  • ◆ Before replacing a component shown as faulty, check wiring and connectors to component as well as earth connections according to current flow diagram.
  • ◆ After carrying out repairs, activate and deactivate system once. Then interrogate fault memory again with fault reader V.A.G 1551 and erase memory.
  • ◆ The fault memory records all static and sporadic faults.
    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.
  • ◆ All faults present are set to sporadic after activation and are only stored as being static if they are still present on completion of checking.
  • ◆ Sporadic faults which no longer occur after 50 activation cycles are erased automatically.
