Problem:

Need help reading uPD70F3624 by Xhorse VVDI Prog.  Connected in-circuit according to their scheme.  But the programmer does not see the ID.

Gives: Try Frequency failed

Try low frequency, still no luck. It doesn’t even give me an ID.

Technical Support:

If the ELV Renesas is alive and correctly soldered according to the scheme, then it should connect and read the ID without raising/lowing frequency.

It vvdi prog cannot read the ID, it will not read the mcu.  This was confirmed by xhorse engineer.

Which tool will read?

Here is the user’s working experience. Share for purpose.

‘I read the Uart mode in orange. At first, the orange5 programmer also refused to read, until I set the quartz frequency to 2000 kHz and after clicking on the MCU info icon, he gave me the MK parameters and it turned out that the MK was 70F3371 and not 70F3624 as it was written on the stone. After choosing 70F3371 and setting the frequency to 8000 kHz, everything was fine.

This is my setup and cable i am using.

I am supplying the unit with 12 volt supply.

 Today I’m siting in a 2013 Mercedes Benz C63 AMG. And I’m going to program a BE Key with Xhorse VVDI Key Tool Plus for this car by OBD. We’ll also need an original key in the procedure.

Connect VVDI Key Tool Plus into OBD.

Pull the Start button out on this.

Read & Save EIS File

Remote programming >> Benz >> Automatically diagnose models >> Start programming

It’s telling me we have 7 times for paid calculation, so you need to have enough MB Tokens before going on.

Yes >> Process wizard mode >> Begin

The current type is W172, 204, 207, 212(with ELV), press “Yes” to continue.

Press “Yes” to save the password to EIS file.

In this page, we can see we still have 3 key slots left over.

Press “Yes” to do key adding.

Insert working key to EIS before press “OK”.

 Problem: Is it a normal process during xhorse vvdi mb tool password calculation?? If all key is lost?

vvdi mb keeps saying take IR adapter out of EIS and insert IR adapter to car.

I have a test platform connected. I bought this platform because this has eis cables.

Solution:

You need the MB power adapter, otherwise, you’ll get sore fingers.

That test platform won’t work. The supply voltage must be interrupted at intervals.

vvdi mb+power adapter+eis cables is enough, you can buy ELV ESL cable set for vvdi mb like this:

Can anyone help? I try to install xhorse Vvdi prog software 5.1.8 but keep getting this system error.

‘System error
The code execution cannot proceed becase NetClient.dll was not found.’

Solution:

vvdi prog software works on windows 10 system.

You have to disable windows defender, disable the firewall and antivirus programs.

If still not working,  redownload software and reinstall again.

 Problem:

I was trying to program BMW FEM key with xhorse vvdi2 but failed, threw error sync code lost.

Error: synchronize code between working key and FEM/BDC system was lost.

Anyone know what to do in this case?

Solution:

 Certainly yes. Xhorse VVDI Key Tool Plus Pad is able to read & save VW Skoda Seat VDO NEC+24C32 while OBDSTAR is not communicating. It happened today when I was trying to read the cluster with a working key. By reading with Login Method 3, Xhorse succeed.

How to read NEC+24C32 via VVDI Key Tool Plus?

Immo programming >> VW >> Select by type >> 4th immo system – Volkswagen >> Skoda >> Seat >> Instrument with NEC+24C32 >> Read EEPROM

Xhorse gives us 3 options: Login Method 1-3:

1. Please select the login method, you can choose “Login Method 1” to log in when you are unknown. If the ignition key is inserted or when use the all-key-lost mode, there is the prompt to insert the ignition key, then you can select “Login Method 2” to try, models after 2013 use “Login Method 3”.
2. If a login method causes the instrument to black out or the car can not be started, just power off the car battery then power on again.
3. Please click start button once for the smart key before login.

If I selected Login Method 2, it’ll be the same failure as OBDSTAR.

But if I selected Login Method 3, Xhorse Key Tool Plus can read it successfully. And even I can save the data as well.

In the same way, I can also read & save IMMO data with Login Method 3 successfully.

Everything has read right out of that cluster.
