Repair Op-com Hardware Procedure?

**easyobd** · 14th April, 2011, 06:26 PM

I can see it in Device Manager as OP-COM Interface V2 but when I do test it doesn't past it. PIC 100% programmed.
How to check relay if it's working or not?

...
but - are you sure that the PIC device is fully functional (integrity)?
if yes check the FTDI device functionality (integrity).

Did some try to reflash OP-COM 1.44 to 1.39

...
yes, possible only with external programmer (at least up to know).

Did you use OPCOM FUT to test PIC functionality

Hello,
Today I successfully repaired my OP-Com clone with my PICkit 3.
After I separated one side of R11, the programming work on the first attempt.

Hallo,
Ich habe heute erfolgreich mein OP-Com Clone mit meinem PICkit 3 repariert.
Nachdem ich eine Seite von R11 aufgetrennt hatte, funktionierte die Programmierung im ersten Versuch.

Done it with Willem's ICSP and Winpic800 software. Only needed five little cable...

Hi, I have problem with my chinese opcom, it can't connect to any car.I check the PIC, and is fine even programmed it again, all relays are fine, interface past the test but still can't connect with the cars. I thing it could be L9837D faulty, correct me if I'm wrong or point me where is the problem. My PCB looks like in the picture above, but I can't find schematic for that pcb. The shematic which I found on this forum is diffrent than my hardware. Thank you for any help.

...
the main problem of your tool is L9637D - I have the similar issue with few tools.

Thanks mishu_b, thats what I thought myself. After when I checked it with multimeter and oscilloscope looks on faulty one. After or before I replace it do I have to program it? Do you have maybe shematic for my type of interface, because this one which I found on this forum is for different hardware?
