Notes on processing your "own testing schedule":
Use control unit functions
Perform test modules
Observe current technical information
Rectify faults and perform function test.
Clear all fault memories with <Quick delete>.
Note the following points when performing diagnosis:
1. Starting diagnosis
The current software status for diagnosis programs, including program and data updates
must be loaded in the BMW diagnosis system.
The BMW diagnosis system must be connected to the workshop network so that diagnosis
data can be transmitted to BMW AG. If the Group Tester One is used outside the workshop
environment, the BMW diagnosis system must be reconnected to the workshop network
after at most 40 diagnosis sessions to that the data stored in the equipment can be
Diagnosis data recorded during troubleshooting are important information for
BMW's quality processes. Moreover, the diagnosis protocol is verification that
diagnosis has been properly performed. Warranty claims may be rejected if there
is no diagnosis protocol (cf. current warranty guidelines).
2. Brief test
After vehicle identification, a <brief test> must be performed on all model series from Model
Year 2001 (from E65).
Because of the increasing degree of networking of vehicle systems, it is not
enough to simply read off the fault memories of individual control units when
troubleshooting, as faults affecting several systems (e.g. bus errors) are evaluated
and analysed by more than one control unit.
3. Fault pattern selection
In the event of a specific customer complaint, first perform a brief test to check whether a
corresponding fault pattern is available in the fault pattern selection. This fault pattern must
be selected with <Accept>.
Fault pattern selection contains known fault patterns caused by software errors,
mechanical faults and faults that do not cause a fault memory entry.
4. Working through the "DIS testing schedule"
Based on the faults stored in the vehicle and the selected fault patterns, the diagnosis
system will draw up a testing schedule, the so-called "DIS testing schedule".
