VAG-COM/VCDS EVERYTHING

[shd]

Hey guys, any of you had issues regarding interface stability (like freezing or communication errors) after a few minutes of scanning?
Mine seems to crash in various ways after the temperature of the Atmega 162 goes over 40 Celsius. I don't know if its a bad soldering or another fault, but as soon as i cool it down (using a fan or freeze spray on Atmega) everything comes back to normal.

I've found this behaviour while working on the open interface (top opened) the functionality time increased.

It seems that coding is less intensive and the interface works longer times, vs auto-scanning or poking various CAN modules.

Any thoughts on this? I see Atmega162 has a working temp of over 150 Celsius, so 40 Celsius should not be an issue.

Thanks!

Pics of the interface in question would not hurt.
Also, which version and which loader version are you using?

Atfirst 40C is too much anyway.. it can be becouse of 78L05 is near .. radiating heat.. and i guess there is gal16v8X that uses much more current also K line driver transistor based..

Any specialist here in Actia multi-di@g clone VCIs????

1.jpgactia-multi-di@g-i-2015-on-vw-passat-9.jpgI've recently purchased the clone of I-2015 with s/n(099387) followed the installation directions just carefully, connected the vci to many cars and to my laptop and the driver was installed succefully, The vci green light was flashing which means it's working with no issues, I got the at530 cfg on the usb mode but when it comes to testing it using the AT530 I tick on the Info sign to make sure it's connected but a message shows up saying (Function in progress...) and after a long while of waiting I end up with an another message (Multi-Di@g VCI not responding), same with the multi-di@g software a message shows up saying (Error while downloading the VCI, check that is connected to the tool and to the vehicle).
I kept in mind taking a look at the Device Manager to make sure that the (i+me actia passthru xs) is on the list and I already found it, What can cause that issue? is it the VCI itself damaged or so ??

The interface is this one:

I've tried v6.3 loader and older ones, also various 17.x and 18.x VCDS software versions: all gave the same result, after a few minutes, and some heat, VCDS reports communication errors.

I've raised the 7805 regulator a bit and the cooler helps, buti was wondering if i can get a more permanent solution.

I've also ordered a obd2cartool interface, but after 3 days of troubleshooting it really bugs me this one got away

Any other ideas i can try meanwhile ?

Thanks!

Out of curiousity, can you measure how much of current it draws when connected to +12 V source?
Use a miltimeter in-line to measure that.

[Belalmondeo]

Does anyone here know what's it about when You connect Your vci to the vehicle and to Your own machine and the vci hardware wizard pops up and installed successfully with no problems, but when it comes to testing the vci with the software You have it doesn't work\respond.
any ideas ?

No offence mate, but we talk here about vcd$; it better if you ask seller to help you or try on a dedicated forum if it is one for your tool.

[Belalmondeo]

My apologizes, but it seems that the seller held me down and I only managed to find this forum thinking to have a (j2534 Pass-thru access Multi-Di@g) specialists, but I didn't manage to find them, I can't even sign up on other sites that requires 25$ for subscription which is a high cost for me almost (465 EGP)

Use a miltimeter in-line to measure that.

Its 300mA while idle, and peaks to 600mA while processing various modules.

I've re-solder Atmega162(i thought there is a bad connection somewhere or low solder quality), it looks steady now, even artificially heated to 40-60 Celsius. I'll try it on the car tomorrow.

Thanks!

[hid3]

hm... I'd say that's quite a lot. I remember measuring some time ago and if memory serves me right, then just OBD2 conencted to +12V was drawing about 10 mA (but I may be wrong, that was a lot of time ago).
I'm afraid something more wrong may be with your cable.
How much heat does the 5V supply emit (the 7505) when at idle?

[networkers]

Its 300mA while idle, and peaks to 600mA while processing various modules.

That seem to be to much. I've measured on miscellaneous Interfaces between ~80mA and ~130mA idle.

[hid3]

Probably something is shorted.
I'd start soldering out various components until the current drops.
E.g. CAN controller, K-line controllers (or transistors?), etc..

[shd]

That was much indeed. My readings were wrong. Basically they ranged from 30mA on idle to 80mA on 'load'. I had another issue after re-soldering MCP2515 (the VRef for MCP2551 was dead, but the ohm-meter helped me in this issue) with a 'CAN not ready' message .

After checking all connections, and soldering the remaining pin, everything works great and stable.

@hid3 Temperature was always around 40 Celsius for 7805, load or idle.

Thank you guys for all the support!!! I've learned a lot, and maybe, just maybe, bad soldering / solder quality might be an issue for other users as well.
