GF00.30-P-0001SX System Diagnosis, Function
- MODEL 216.3, 221.0 /1

The fault codes stored in the fault memories of the individual control units can be read out using STAR DIAGNOSIS and evaluated. System diagnosis is incorporated in the central gateway control unit (N93) as a software module.
STAR DIAGNOSIS is connected to the vehicle via the data link connector (X11/4) and the diagnostic CAN via the central gateway control unit (N93).

The central gateway control unit has access to the following bus systems:
- Telematics CAN
- Interior CAN
- Drive train CAN
- Diagnostic CAN
- Chassis CAN
- Central CAN
- Front end CAN
- Vehicle dynamics CAN
- Media-oriented system transport (MOST)

The following information is displayed using STAR DIAGNOSIS for each diagnosis result:
- Control unit version
- Actual values
- Control unit adaptations
- Complete list of conducted tests
- Complete list of fault codes

Programming of the vehicle variants
The different variants, such as special equipment, national and functional variants, are stored in the central gateway control unit at the factory at the end of production and activated specific to the vehicle.

In certain cases, it is necessary for the central gateway control unit to be programmed in the workshop:
- Defective central gateway control unit
- Addition of installation of a new control unit variant to one of the CAN buses or the MOST, which requires an update
