Hello,
This is a very common issue. Editing the
.ini files is only half the battle. You also have to tell ISTA itself which interface to use. Most standalone installations default to ICOM, so you have to manually switch it to use your K+DCAN cable via EDIABAS.
Follow these steps exactly:
1. Configure ISTA VCI Settings
This is the most likely step you are missing.
- Launch ISTA+.
- Click on the wrench icon (Administration) at the top.
- Go to the VCI Config tab.
- You will see a list of interface types. Select "Ediabas default settings (ediabas.ini)".
- Click "OK" and restart ISTA.
This tells ISTA to use the configuration you've set up in your EDIABAS files.
2. Verify Your EDIABAS Configuration
Double-check that your files are correct.
File: C:\EDIABAS\Bin\ediabas.ini
Make sure the
[Interface] section looks like this:
INI:
[Interface]
Interface = STD:OBD
File: C:\EDIABAS\Bin\obd.ini
Make sure the
[OBD] section points to the correct COM port you set in Device Manager.
INI:
[OBD]
Port=ComX ; Replace X with your COM port number
Hardware=OBD
3. Verify Windows Device Manager Settings
This is critical. The COM port in
obd.ini must match what Windows has assigned to your cable.
- Plug in your K+DCAN cable.
- Open Device Manager (right-click the Start button and select it).
- Expand the "Ports (COM & LPT)" section.
- You should see your USB cable listed (e.g., "USB sеriаl Port (COM3)"). Note the COM port number.
- Right-click on it and go to
Properties -> Port Settings tab -> Advanced....
- Ensure the COM Port Number here is the same one you used in
obd.ini. You can change it here if needed (use a low number like 1-4).
- While you are in this screen, set the "Latency Timer (msec)" to 1. This is very important for performance.
- Click OK on all windows to save.
Summary Checklist:
- ISTA VCI Config is set to "Ediabas default settings".
- Device Manager shows your cable on a specific COM port (e.g., COM3) with latency set to 1.
- Your
obd.ini file has Port=Com3 (or whatever your port is).
- Your
ediabas.ini file has Interface = STD:OBD.
If you've done all of the above, it should work. If you are trying to connect to an F/G/I-series car, you need an ENET cable, not a K+DCAN, and the setup is completely different (no COM ports or ediabas.ini edits needed).
