System.TimeoutException

Hello @gmenounos -

I'm receiving the following from my ECU:

This occurs with any ECU command. I have successfully used the VAG KKL cable on another ECU, and I have successfully used a ross-tech cable and VCDS on this ECU. I am bench testing this ECU, so no other controllers are available.

Can you advise on best practices to troubleshoot this timeout?

Thanks, Matt

PS: FYI, I'm a programmer by trade, but new to ECUs and the EDC15.

[gmenounos]

What's the part number of the ECU? Which VCDS cable?

[roder]

[roder]

Thanks for your super fast response BTW!

[roder]

@gmenounos part number is 038 906 012 FD

@gmenounos the ross-tech cable is:

Kii-USB Hc165365 rev A

[gmenounos]

Make sure you have "Boot in Intelligent Mode" UNchecked in the VCDS settings. If it's checked and you uncheck it, you'll need to unplug the cable from the PC and plug it back in again for the setting to take effect.

And, you're successfully able to connect to this ECU on the bench with VCDS? And then you try kw1281test and it always gives the timeout?

[roder]

I followed this procedure from the bench:

1. Connected to ECU via ross-tech with VCDS, confirmed successful reads from controller 1.
2. Unchecked "Boot in Intelligent Mode" in VCDS Options dialog, Applied and Saved config.
3. Disconnected power from ECU and disconnected Ross-Tech cable from laptop and ECU.
4. Reconnected Ross-Tech cable, tried .\kw1281test.exe com4 9600 1 ReadIdent on all four com ports (com1, com2, etc) - System.IO.FileNotFoundException on all 4 com ports.
5. Disconnected power from ECU and disconnected Ross-Tech cable from laptop and ECU.
6. Connected VAG KKL cable and executed .\kw1281test.exe com4 9600 1 ReadIdent.

Yes, I'm getting a consistent timeout from kw1281test everytime and yes, I'm able to successfully read the identity (VIN, etc) with VCDS on the bench.

[gmenounos]

Thanks for the detailed report. The reason kw1281test isn't working with your VCDS cable is that you need to install the RossTech Virtual COM Port (VCP) drivers in order for the VCDS cable to appear as a COM port. Instructions are here: https://sites.google.com/site/imnuts/home/install-setup-ross-tech-vcp-drivers I'm not optimistic that that will magically fix your issue, but it's something you can try while I try to figure out what the problem is.

[gmenounos]

Try this new release: https://github.com/gmenounos/kw1281test/releases/tag/v0.94-beta I added some additional logging.

@gmenounos your support is amazing! 🙏 🙇

TL;DR - Its working!

The long story...

I followed the steps to use the Ross-Tech KII-USB cable in the document that you gave me. When I reached this section:

Now that VCP has been enabled, you should have a new option in Device Manager. Odds are, your computer didn't come with a serial (COM) or parallel (LPT) port, so Ports (COM & LPT) should be new for you. If it isn't, this will be a little more difficult, but not much. Expand the listing. If more than one item is listed, you'll need to find the correct item. Right click on one, or the only one, and select properties. If you have more than one, the manufacturer listed should be Ross-Tech. If it is, you selected the right one.

I did not have the Ports (COM & LPT) in the device manager, but there was another section called Other Devices which had a USB Com Device with no drivers identified. However, I noticed in the Ross-Tech Drivers, there was another driver file called ftdiport.inf, so I followed the same steps to manually load that driver for the new, unknown USB COM device (which was identified as a Ross-Tech Device).

Once I loaded the ftdiport.inf, I ran the following successfully with the Ross-Tech KII-USB cable:

C:\Users\Matt Heitzenroder\Documents\Autos\TDI\kw1281test_0.93.0-beta_Win10> .\kw1281test.exe com5 9600 1 ReadIdent

Thank you so much again, for the amazing and fast support. The outcome was better than expected - now I have one cable to rule them all!

I can code, but I haven't ever written any .NET. I'm quick to learn new languages though, so If there's any way I can support your project, I'd love too. Want help with documentation or fixing bugs (or anything else)?

PS: If there isn't anything else, feel free to close this issue.
