8.5 - Fault table
Notes:
◆ Faults occurring in monitored sensors or components are stored in fault memory together with an indication
of the type of fault.
◆ The fault table is arranged according to the 5-digit fault codes on the left.
◆ 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 "sporadic" also appears on 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 greater than 30 km/h).
◆ Do not immediately replace components indicated as being defective by VAS 5051, but rather: Start by
checking wiring and connectors to these components in line with current flow diagram. Also use current flow
diagram to check earth connections. This is particularly important if faults are output as being "sporadic".
◆ On completion of repair work, fault memory is to be interrogated again and erased.

00532
Supply voltage
- Signal too low - Open circuit in wiring or short circuit
in power supply
- Use current flow diagram to perform
fault-finding
00625
Speed signal
- Implausible signal - Fault is set if vehicle-speed signal is
implausible (e.g. 500 km/h); occurs,
for example, in the event of loose
contact in wiring
- Use current flow diagram to perform
fault-finding
