VAG-COM/VCDS EVERYTHING

[antibisic]

Take some high quality pictures from both sides of the PCB.

Make sure that the photos show clearly the IC's labels.

Good luck

Sorry for bad pictures but in workshop only had a phone and I write on which ic is.Tryed some dumps for atmega but allways when I conect red led is on.Regards

Your have a good hardware... and with this one you don't need to remove any component.

Regarding your problem you might try the following:

1) Check if you have 5V at the output of the voltage regulator (7805).

2) Is your cable recognized as Ross-Tech cable when you plug it in the USB port?

3) Make sure you have good dumps (FLASH + EEPROM) and that you use the corresponding original installer.

4) Make sure you are using the correct *.ept file for the FTDI's EEPROM.

5) Are you flashing both memories of the ATMEGA? FLASH + EEPROM?

6) Which programmer (hardware and software ) are you using?

Good luck.

1.I allready checked and voltage regulator is ok

2.Yes my cabel is recognised when I plug in the usb port

3.I tryed several dumps and with all is same

4.I used 805 and 908 ept file for 908 atmega dump and same thing

5.Yes of course I am flashing both

6.I am useing upa usb orig

But one thing is not clear to me,first I erase the atmega and than when I read fuse bits it is still there!Why when is mcu erased maybe this make me trouble because I write than new dumps over this fuses.Maybe atmega is faulty,or I shoud try with x-prog?Thanks

The problem are not the fuse bits being or not being erased during the reflash.

That is, if the fuse bits are correct, you don't even need to set them again.

Which fuses are you using?

Try to use eXtremeburner and use this fuses:
LOW: CD
HIGH: DC
EXT: F9
LOCK: FF (you can read the content of the ATMEGA's memory after programming) or CC (you can't read the content ATMEGA's memory after program)

Good luck

I use fuses like other here from pony prog soft and I used this before when I programed my vcds without problem

If you double check everything I said above, I might suggest that you may have a faulty IC.


1 - Can controller MCP2515
2 - Can Transceiver TJA1050
3 - uC ATMEGA162

I think you are right probable atmega 16 is gone,if ic,s mcp2515 and tja1050 gone shoud interface make test and give eror with can?thank you

When the cable is powered via ODB (12V) and if you make a test I think you're just testing the license, so, only the ATMEGA.

I believe that the test button won't give any report about the CAN communication (correct me if I am wrong).

So, if you're having troubles only when you try to communicate with the ECU, I might suggest that the problem is the CAN communication HW (MCP2515 or TJA1050).

However, it could also be the ATMEGA... or a resistor, or a capacitor... or a broken cooper track... If you understand what I mean, it could be anything. So, you must make a throughout analysis.

If I am wrong please correct me Thanks

I double checked all tranzistors,resistors and capatitors.If can ic is broken than sholud not work all what come via can comunication but not all ecus works via can example motor ecu works via K-line and k-line goes over transistors not over can ic.In this case in test screen should apear
Can 1 not ok
can 2 not ok
k-line ok
Maybe I wrong but I think so

You're right: CAN goes over MCP2515 and TJA1050. For KKL the communication is via transistor.

Then, maybe the ATMEGA is faulty.

Did you use tried the cable in other cars?

Hi dear friends
I need lile help ,sugestions
Yestoday get one vcds clone 11.10,after insatll on pc get the error like in picture wath i attash,the cable dont find any drivers and can not install,the cable its new,i try to install on other pc but same problem.
Can somone tellme wats wrong?
Thank u for any sugestion
Regards

[mladen76]

Maybe it is your operating system in question mate.
W7 64 bit ???
Try to download original RossTech installer,and after you install drivers whit it uninstall original program and install one you got
whit your interface.

Right clik on and Unistall drivers
Then when it will ask you to install driver do it manually
If this will not help you, then use the FTCleanner and unistall all VID_0403/PID_FA20 drivers
Then you'll be able to install it
Good luck

So, you tried at least in two cars? Right? Then we can now exclude that the problem was the car itself.

If you used original installer, good dumps for uC and FTDI and if you tried the cable on several cars....

... I think that you have a HW problem. If you say the cable won't connect on KKL or CAN... then you might have a problem in the uC.

Try replace the ATMEGA.

Post the results.

Good luck
