6 Functional Description
6.1 Diagnostics
6.1.1 DoIP connection
Interface to diagnostics functionality is via the DLC Ethernet interface. This interface should be
connected to DoIP interface in the vehicle, located in the OBD connector.
When test equipment is connected to the OBD Ethernet port in the vehicle, the ACUII-06 presents
itself on the network using a “Vehicle Announcement Message”, as specified in ISO 13400-2.
Based on the content of this message, an external tester tool can connect to the ACUII-06 and
create a diagnostic session.
6.1.2 CAN connection
The can interface of ACUII-06 should also be connected to the OBD connector in the vehicle.
To communicate with the ACUII-06 and the ECUs behind the ACUII-06 in the vehicle topology,
the diagnostic requests shall be sent with 29-bit addressing.
The same CAN interface is used for legislated ODB diagnostics. For such purposes, 11-bit
addressing is used.
6.1.3 WLAN
Diagnostics functionality is also available via WLAN. The unit ca be set in a mode where it acts
like a WLAN station and attaches to a hotspot in the workshop.
6.2 WLAN access point
ACUII-06 can act as a WLAN access point for passengers in the car.
User interface needs to be implemented in an external unit, e.g. in a head unit with display. The
WLAN access point functionality is controlled via IHU Ethernet interface.
6.3 Data gateway
ACUII-06 acts as a data gateway for the WLAN access point and other ECUs in the vehicle. It can
e.g. provide internet connectivity for the head unit.
The data gateway is controlled via the IHU Ethernet interface.
6.4 Positioning information
The product automatically outputs GNSS raw position data on the CAN bus.
The GNSS data is used by other ECUs in the vehicle, for instance the Navigation system
6.5 Telematics applications
The product hosts a number of telematics applications. Some examples:
