1.5 - 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 (ambient temperature sender at
least 60 seconds, coolant temperature sender only after engine has been running for at least 30 minutes).
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".
◆ 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.
◆ On completion of repair work, fault memory is to be interrogated again and erased.
