Parking aid (parking system) self-diagnosis
Parking aid fault table
Notes:
-
◆ Listed in the following in ascending order of 5-digit fault codes are all the faults which can be detected by the parking aid and printed out on V.A.G 1551.
-
◆ 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 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 are erased if they do not re-occur in the course of 50 driving cycles (ignition on for at least 5 minutes, vehicle speed > 30 km/h).
-
◆ When eliminating an open circuit in the event of a data bus fault, always remember to twist the two data wires of the corresponding bus system together to prevent electromagnetic interference.
