Fault table for telematics system
Notes:
◆ The following table lists all the faults which can be recognised by the telematics system and printed out by the V.A.G 1551. The faults are listed in order according to their 5-figure code numbers.
◆ The fault code only appears on the printout.
◆ Before replacing components found to be defective, use current flow diagram to check wiring and connectors to these components as well as earth connections.
◆ On completion of repair work and system functional test, always interrogate fault memory again with fault reader V.A.G 1551 and erase it.
◆ All static and sporadic faults are stored in the fault memory: A fault is recognised as being static if it is present for at least 2 seconds. If a fault is then no longer present, it is stored as being sporadic and "/SP" appears on the right of the display.
◆ After switching on ignition, all faults present are set to sporadic and only stored as being static if they are still present after checking.
◆ Sporadic faults which do not re-occur in the course of 40 switching on and off cycles of telematics system are erased.
