3DColorMFD ver. 7.8.1
You will need:
|Soldering iron 40 W|
|Nippers||Pliers||Knife||Thermocouples||And screwdriver Torx T10|
ATTENTION!!! When installing a color MFD, there are 3 most important points.
Bend all the latches neatly remove the front of the case with glass
View from above
Then remove the substrate.
1.3 Cut the jumpers, we work carefully, so as not to damage the board.
It should look like this:
It is necessary to remove the display by gently heating the loop with which it is soldered to the board,
do not tear off the display as you can damage the dashboard board.
1.5 With the help of pliers, we bend the metal clamps restraining fullFIS display.
1.8. Then you need to remove all the LEDs that are were under the standard display
We make sure that there are no jumpers made of tin.
After removing the LEDs, clean the board from tin residues and rinse with alcohol.
1.9 VERY IMPORTANT:
For instruments with a halfFIS or fullFIS installed, it is necessary to find and cut
tracks from the pins of the control of the standard FIS
on the board of the instrument panel (from the pins 23, 24, 25 of the green connector)
After need to check that the 23, 24, 25 pins were 0v
Below are photos from some instruments.
On your device, the tracks may be located elsewhere
For dash have noFIS, you just need to check that the 23, 24, 25 pins were 0v
1.10. We start to build wires according to the table. Wires are cleaned of
Isolation and twisting, ludim and cut off excess.
1.11. Through the holes in the board of the device, we extend the wires to the blue
And green connectors.
2.3 Take the multimeter, set it to Diode (Ring) mode.
Using multimeter and wiring diagram, find the wires you need and solder them to the connector pins.
13. Using the tester, we find the wires we need and solder them to the feet connector according to the table.
There are 2 ways to connect CAN bus wires. Choose what is convenient for you.
|1-st way: solder the wires to to the pins of the green connector||2-nd way: solder the wires to the points, indicated in the photo|
2.5 Lay the wires in such a way that they do not interfere with the installation of white Light diffuser.
You need to remove 3kOhm (302 or 3001) resistor from 36 pin of MFD board.
Or, after installation, you need to connect MFD to the Shell program and configure the low oil warning for the FullFIS cluster.
Shell program link:
If you are the lucky owner of Passat B5, released for USA market, you have to add a few SMD resistors to the dashboard.
In clusters for the American market, there are no open hood and
oil level control resistors, and there are no oil level and temperature sensors in the engine sump.
2.7 The wires should be pulled from the back or as shown above.
Wires should not interfere with the assembly of the cluster.
So it’s not right!
2.8 Power connection
There are two types of power supplies
Before installing the power supply, you need to solder the wires to its contacts IN+, IN- and OUT+, OUT- ,
then apply a current of 12V to IN+, IN- , and connect the OUT+, OUT- wires to the multimeter.
Now we need to tune the output current. Using a small flat screwdriver, you should rotate tuning resistor
clockwise, until you have 5.5V output voltage on the multimeter.
Next, we place the power supply on the cluster`s back board and bring wires from the blue connector to its contacts.
How to do this, look at the connection diagram specifically for your car model.
Choose the installation location of the power supply so that it does not interfere later in the assembly. For example:
After wiring, lay it so that they do not interfere with further assembly.
Need to call all contacts and check on the table to avoid confusion anywhere.
2.9 Before assembly, check the functionality of the module in your car.
After wiring, lay it so that they do not interfere with further assembly. Check wiring with multimeter, in Diode mode.
On the display, at the back, there is a piece of double-sided tape (if yours doesn`t have it, attach one). Don`t remove the protective film from it! We use it only as a support for the display!
|Do not solder these wires! Pins 6 and 7 are spare.|
|3.1 Cut off Red USB wire, we don`t need it.||3.2 USB cable should be fixed with glue.|
3.3 We take double-sided adhesive tape on a foamy basis, cut the squares 1cm X 1cm.
3.4 Collect these squares in 3 floors.
3.5 Place them so that nothing prevents you from mounting the module on the board.
3.6 Place the module so that it fits in the cluster`s window.
3.7 Cut off the main beam guide part. On the red line. Leave the semicircle.
3.8 Cut off the protruding part!
3.9 Install a white diffuser and cut off the excess (as shown in the picture).
Then place the display and align it so that it clearly fits into the cluster window.
3.10 IMPORTANT! For greater stability, after you have tried and calibrated it, fix its position with hot-melt adhesive.
3.11 Next, you need to glue the matte protective film so that the display does not glare in the sun.
Be sure to stick the film!
Otherwise, the display may be damaged!
4.1 IMMO3 Cluster Installation in a vehicle with IMMO2
If you are installing IMMO 3 cluster in a car with 1J0 CCMS (comfort unit) — you shoul remove 2 resistors from the cluster board.
These resistors are coming from 8 and 9 pins of the green connector.
4.2 If you are Installating IMMO3 cluster in a vehicle with IMMO2,
you should activate the ambient temperature sensor in the cluster`s EEprom.
You need to change 1ef from 08 to 01
line 0001E0 column F
Cluster 1J0920806G no fis no show temp in dispay
You need to change 1e5 from 2B to 2F
line 0001E0 column 5
Change 2B in 2F and work
I changed that one 1E0 column 6 from 2B to 2F and it works
To connect the boost pressure control, You need to add pin 15 to the green connector.
The other end of the wire must be connected to the engine ECU.
According to the table below, you should find the signal wire of the boost sensor.
When the engine is idling, the voltage on the wire should be between 1.6 and 1.9 volts.
With an increase in RPM (engine speed), the voltage on this wire should increase.
On diesel engines (AVB and others):
— 71st pint of ECU, green — red Wire (green with a red stripe);
On petrol (AWM and others):
— 101 pin of ECU, gray — blue wire (gray with a blue stripe).
In general, as I know, in all B5 diesel 1.9Turbo, supercharging is connected to the 71st pin,
And the gasoline 1.8T is connected to the 101 pin. The color of the wire can vary depending on the year / engine.
Collect everything in the reverse order, without forgetting to calibrate the needles with the help of the VAG-com program.
6.1 To do this, connect cluster to the car (without cluster glass) and connect it with VAG-com.
6.2 Go to unit-17.
6.3 Select Test unit.
6.4 Make a needle test.
The needles will make a turn on the whole scale, and then freeze.
Remember or make a photo of difference in readings. Click «Done» and exit from the unit. Turn off ignition, remove the key and set the needles to correct position, turning them back counterclockwise.
6.6. Tachometer — 3, 000 RPM.
6.8. Speedometer — at 100 km / h
6.9. Coolant temp. — middle
6.7. Fuel level — middle
Then check everything again
You can not turn the needles too quickly correcting the position, you can damage the motors of the needles
You can not turn the needles, when there is power on the device.
6.6 Put back the cluster glass and put the cluster back into the car.
7. Take a photo and post it on all social networks.
Go to auto club meeting and brag to your friends.
8. Show it to your girlfriend/wife with words: «Look what a cool thing I bought for just 20 bucks! » =)
