that is the test plan for all the faults in the list

Fault description
 The control units exchange information via the bus.
An "interface error" (invalid signal) is stored when urgently
required signals are only received in the form of a substitute
value or as an "invalid signal".
The fault is logged when the partner control unit (=interface)
transmits a substitute value or a value designated as invalid
instead of the required information. In this case, a fault should
also be stored in the corresponding partner control unit.
Condition for fault identification
Supply voltage between 9 and 16 volts.
PRD status: Driving
PRD status: Testing-analysis-diagnosis
Condition for fault memory entry
The fault is entered after a maximum of 10 seconds after

having started the control unit.
Action in service 
Work through all stored faults of the partner control unit

according to the test plan.

Especially faults that affect the vicinity of the partner control unit

(e.g. connected sensor system).

These types of faults are consequential faults.

If there are no further test modules in the test plan then no

further repair measures are required.
Note on effect of fault
 Possible perceptible consequence for the customer:

l Parking Manoeuvring Assistant not working.

l Parking assistant not working.

l Reversing assistant not working.

l Parking aid not working.

Driver information
 Possible Check Control messages:

Check Control message (490): Park assistant.

Check Control message (918): Parking help failed.

CC message (977): Side protection.

Check Control message (2026): Reversing assistant. Drive on

your own.
Service instruction 
The fault is not in the control unit that records the interface fault.

For this reason the control unit must not be replaced.
