1 PRODUCT DESCRIPTION
1.1 GENERAL
ACU6 is a telematics product for vehicles. It provides data connection over cellular networks for embedded
telematics applications. It also provides data connection for other devices in the vehicle, such as the
infotainment head unit.
ACU6 has WLAN functionality and can act as both access point and station.
Hands-free voice calls are possible for telematics services, like emergency calls and breakdown calls. A voice
call is started by using specific buttons in the car, or automatically triggered after a crash. The voice call is set
up to a pre-defined number (depending on country).
The product can be attached to external antennas, but also have internal antennas that can be used if e.g. an
external antenna would be broken. There is also an internal backup battery that is used if the external power
source (vehicle battery) is lost.
1.2 CONNECTORS
1. Violet Fakra (code D) LTE main antenna
2. Red Fakra LTE diversity antenna
3. Blue Fakra GNSS antenna
4. Violet Fakra (code H) WLAN antenna
5. HSD connector Ethernet and USB
6. 22-pin JAE Main connector (power supply, CAN, buttons, audio...)
1.3 SIM
The product has an internal eSIM that is soldered to the PCB.
It is also possible to attach a micro-SIM (3FF) to a SIM tray inside the product. The SIM card is placed in the
SIM tray during manufacturing. The product is not designed so that the user can replace the SIM.

3 FUNCTIONAL DESCRIPTION
3.1 CAN CONNECTION
ACU6 has a CAN interface for connection to CAN buss vehicles. CAN data can be sent and received.
3.2 WLAN STATION
The unit ca be set in a mode where it acts like a WLAN station. This mode can e.g. be used for connection to
a hotspot in a workshop.
3.3 WLAN ACCESS POINT
ACU6 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.
3.4 DATA GATEWAY
ACU6 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.
3.5 POSITIONING INFORMATION
The product can send GNSS position data on the CAN bus. The GNSS data can be used by other ECUs in the
vehicle, for instance the navigation system.
3.6 TELEMATICS APPLICATIONS
The product hosts a number of telematics applications. Some examples:
3.6.1 Automatic emergency call
If the car is in a crash and the SRS control unit indicates seat belt pretensioners, airbags or inflatable curtain
has deployed, an automatic call is sent to an OEM’s customer call center. ACU6 does not support 911
emergency calls.
Should the vehicle´s power feed be compromised the TCU has it’s own backup battery in order to self-
sustain the emergency call process.
3.6.2 Manual emergency call
It is also possible to manually start an emergency call to a customer call center by pressing a button.
3.6.3 Theft warning
The call center and the car owner are contacted with a data message if the car alarm indicates the car is
being stolen. The ACU6 is connected to the cloud and can detect tampering such as towing or power
manipulation. The ACU6 will the engage theft notification and enter alert mode.
3.6.4 Stolen vehicle tracking
The call center can initiate tracking of the car if it has been reported stolen. The vehicle location will then be
reported to the call center.
