Diagnosis
Most diagnosis procedures for the new Navigation Plus system can be performed using the diagnostic tester.
In addition to the extended control unit identification, the following functions are available: data blocks,
coding and adaptation functions as well as sequential and selective final control tests.
The control unit identification contains two different part numbers, one for the hardware and one for the
software.
Entries in the fault memory are stored together with environmental conditions. The following table shows
how they are interpreted:
