1Description and scope of delivery
Thank you for purchasing your VADpro VAD15 / CANchecked MFD15 Gen2. With the VADpro data
display, you can display live data from your vehicle while driving, log sensors and use many other
functions that are presented to you in this manual. In some cases, additional licenses are required
for the functions.
This guide applies not only to the VADpro VAD15 / CANchecked MFD15 Gen2, but also to MFA2.0
Gen2.
This guide explains how to operate and handle your Gen2 data display. In addition to the connection,
setup and navigation, this manual deals specifically with the individual setting of the data display, as
well as the connection and operation of our "online display setup software" (oDSS).
You received your data display with a vehicle-specific bracket or as a pure circular display. Always
included are:
•the Quickstartguide
•2 anti reflexfoils
•CANchecked stickers
•two Molex connectors (6 pin and 12 pin), a selection of different pre-crimped leads, pins for
self-crimping and two 1kohm resistors
Your display itself has an OLED display, an LED, a Wi-Fi hotspot, three Molex jacks on the back and a
MicroUSB port on the board. This is not accessible without dismantling the display and usually does
not have to be used by the user. Your data display will be delivered with a selection of TRI files pre-
installed in the file system.
Terms associated with the data display are shown in italics in this guide for better understanding.

2Connection of the plugs
To operate your MFD15 Gen2 via the Can bus, only four wires are required:
•12 volts on-board voltage, ideally ignition plus - >Pin B5
•Ground -> Pin B6
•Can High (CanH) -> Pin C7
•Can Low (CanL) -> Pin C8
The wires of CanH and CanL should always be designed as twisted pairs in order to minimize
interference signals.
Figure 1: MFD15 Gen2 Pinout
Of course, CanH and CanL are not necessarily necessary for operation. Via the six analog inputs (AINs
–analog inputs) you can also feed the 0-5 volt voltages of analog sensors into the display and have
them converted by the display and monitored on it.
By default, four of the AINs are preconfigured for different sensors:
•AIN1: Oil temperature (OilT) -> Pin C2
•AIN2: Exhaust gas temperature (EGT) -> Pin C3
•AIN3: Oil pressure (OilP) -> Pin C4
•AIN4: Boost (MAP) -> Pin C5
The analog inputs five (pin C9) and six (pin C10) are not preconfigured.

Rev 1.0
6
The power supply for operating the analog sensors can also be realized directly via the display. Pin C6
is 5V, and the sensor ground can be obtained from the SensorGround C12. The maximum current of
0.5 amperes should not be exceeded.
Furthermore, the MFD15 Gen2 has two MultiPurpose Pins (MPPs). Various functions can be realized
via these pins. Read more in Chapter 7.
Basic settings such as active TRI file, can speed and termination can be adjusted directly via the
display. If the Can Bus connection is successful, the symbol in the topbar is displayed in green, if it is
not successful, the symbol is displayed in red. The TRI file is engine-specific and is described in
chapter 8.1.
All further settings are made via Wi-Fi connection via the oDSS. By default, Wi-Fi is disabled on the
MFD15 Gen2. The TRI file can be edited via the oDSS or for TRI files for freely programmable engine
ECUs via the DSS.
The oDSS starts web-based without installation via the browser of your device.
The DSS must be downloaded and installed for use. The download is free of charge at
https://www.canchecked.de/downloads-category/dss-display-setup-software/. The DSS is available
for Win32, Win64 and MacOS.
In the meantime, we have produced illustrated installation instructions for numerous vehicles. These
can be found on our website under www.canchecked.de/help/einbauanleitungen/. If you have a
CANchecked data display with a plug-and-play OBD data cable, it is recommended to connect it
briefly with the data display to the OBD socket before final installation behind the fairing in order to
check the correct connection and familiarize yourself with the user interface.

3Navigation on the display
Your data display can be operated via the two buttons on the front as well as using the CANchecked
knob (CC20001).
3.1 Using the buttons on the display
The two buttons (L/R) are embedded on the left and right of the front of the plexiglass pane.
Attention: With the MFA 2.0 Gen2 these buttons are not available, for this reason a rotary knob is
always included in this configuration.
If both buttons are pressed and held simultaneously (L+R) before switching on the data display, you
will be taken to the menu instead of the regular page view, in the menu you can define the basic
settings.
Figure 2: Page view
Figure 3: Menu
The assignment of the functions of the buttons can be freely defined in the oDSS. By default, the
buttons are assigned as follows:
The left button (L) changes with a short press:
•In page view, moves the page to the left
•In the menu the selection to the top
The right button (R) changes with a short press:
•On the page view, moves the page to the right
•In the menu the selection down
Briefly pressing (tapping) both buttons simultaneously (L+R):
•Has no effect in page view
•Confirms the current selection in the menu
The long press (three seconds) of both buttons at the same time (L+R):
•Turns Wi-Fi on or off on the page view
•Has no effect in the menu

3.2 Using of a separate rotary knob
The MFA 2.0 Gen2 comes standard with a rotary knob. However, the rotary knob can also be
connected as an additional add-on to any MFD15 Gen2 to extend the functionality.
If the rotary potentiometer is pressed and held before switching on the data display, you will be
taken to the menu navigation instead of the regular page view.
The assignment of the functions of the rotary potentiometer can be freely defined in the oDSS. By
default, the buttons are assigned as follows:
Turning the knob to the left changes:
•In page view, moves the page to the left
•In the menu the selection to the top
Turning the knob to the right changes:
•On the page view, moves to the right
•In the menu moves the selection down
The short-term pressing (tapping) of the rotary knob:
•Has no effect in page view
•Confirms the current selection in the menu
The long press (three seconds) of the rotary knob:
•Turns Wi-Fi on or off on page view
•Has no effect in the menu

4Connecting to the oDSS
The oDSS can be run on any browser and Wi-Fi-enabled device. You can use both your smartphone or
your laptop.
To connect to the oDSS, the first step is to activate the Wi-Fi hotspot on your MFD15 Gen2. To
activate, both buttons (L+R) or the rotary potentiometer must be held down when the ignition is
switched on. The display will then show you two QR codes one after the other.
The first QR code is used to connect your device to the hotspot, the second QR code opens the
address of the MFD15 hotspot in your browser. Please wait some seconds after scanning the first QR-
Code for the device to switch to the second one.
If you cannot scan the QR codes, the name (MFD15) and password (12345678) of the hotspot, as well
as IP address (192.168.4.1) for the oDSS are displayed below the QR codes, so that you can also
connect via the normal Wi-Fi menu and the browser.
If the connection is successful, the topbar is now permanently displayed and the Wi-Fi icon is
displayed in green.
ATTENTION: If you are connected to the MFD15 hotspot, you will no longer have regular Internet
reception. If you want to update the data display or upload your own image, the files must first be
stored locally on your device and can no longer be downloaded from the cloud or similar online
services.
Some phones might not be able to connect to the device if the GSM/3G/4G/5G has an active
connection, so you might have to temporarily disconnect the cellular network on the phone.

5Updating the MFD15 Gen2
The MFD15 Gen2 can be updated wirelessly or via WLAN from the oDSS, or via USB cable with the
CANchecked MFD15Gen2Updater.
5.1 5.1 Online update from the oDSS
The Update Device section of the oDSS is used to upload new firmware and file systems.
The firmware is the operating system of your data display, and the file system contains new TRI files.
The .bin files for over-the-air updates can be found at
https://www.canchecked.de/downloads/downloads-mfd15-mfa20-gen2/.
To update from the oDSS, press the Start Update button and select the appropriate .bin file. The
update starts, the bar runs through, and the display then reboots automatically. Afterwards, the
WLAN must be reactivated and the connection to the hotspot must be re-established for further
configuration.
Figure 6: oDSS Update
5.2 Wired update via USB
The MFD15 Gen2 has a microUSB port on the circuit board. To access this, the MFD15 must be
disassembled. It is easier to connect the MFD15 Gen2 to a PC via the six-pin Molex connector B. The
TTL adapter from the Gen1 does not work here! If your kit does not come with a Molex USB
connector, you can pin it yourself with this pinout:
Figure 7: USB Cable Colors
Of course, you can also build the USB cable yourself, if you have the possibility to crimp the Molex
contacts yourself. Once you have stripped your USB data cable so far, the individual wires must be
professionally crimped and pinned into the six-pin Molex connector as follows:
•White: USB Data- -> Pin B1
•Green: USB Data+ - > Pin B2
•Red: USB 5V -> Pin B3
•Black: USB GND -> Pin B4

Once you have successfully connected your MFD15 Gen2 via USB, you will need the
CANcheckedUpdater and the appropriate .flash file, both of which can be found here:
https://www.canchecked.de/downloads/downloads-mfd15-mfa20-gen2/
In addition, the appropriate driver is also offered on the website. To update the display wired, you
need to run the updater and make sure that your MFD15 Gen2 is recognized as shown in the
following picture.
Figure 8: CancheckedUpdater
Now you can use the "Select Firmware" button to load the .flash file that you previously downloaded
from the website into the updater. After the updater has checked the file, the previously greyed out
"Start Update" button becomes visible, and the update is started by clicking on the button. You can
follow the progress in the loading bar of the updater. After a successful update, your display reboots.
