Is there any controller in that car that you can connect?
If you cannot connect to any controller in that car then the issues could be a driver issue or the MCU ( PIC18F458 ) could be a fake blocked one.
You have a Rev B so you can rework it to Rev C. The Rev D it is different hardware
Good luck

P.S. - By team viewer I can help you test if you have a fake MCU or if you have a corrupted or bad driver setting.
By your board pics it seems that you have a fake MCU but if you can test this you will be sure.

OK, I can arrange for teamviewer maybe tomorrow. I was able to downgrade firmware and upgrade again so I thought the interface was genuine.

I am able to connect to controllers like airbag, radio and cluster. Indeed I cant connect to the HSCAN controllers including body domain controller

RE: OP-COM 2020 FREE 4 ALL
Well if you was able to downgrade and upgrade the firmware and the interface can connect to some controllers then the MCU is a real but not a fake one.
In this case you do not need me to do any tests because your issue is the HS-CAN defective in your interface.
You can check the relay and also you can check the CAN BUS transceiver for HS-CAN.
Good luck

RE: OP-COM 2020 FREE 4 ALL
Hi, I need help to repair my opcom.  I have a genuine revision d opcom which has been working great with opcom professional on firmware v1.66.  I needed to pull a code from a dec30 ecu so downloaded advanced version by Fantomel. Version 16.x.x worked great and I got the security code. i then proceded to try version 19.x.x and I clicked test interface. This immediately flashed v1.67 firmware to my opcom. After this it no longer connects to the car. I tried opcomfut and it says pic empty. I couldnt flash firmware back using this tool.  I hooked up my pickit2 and flashed the only firmware I have which is V139 + bootloader. It writes ok but opcomfut still says pic empty. Anyone got any idea how I can get this working again. Thanks

RE: OP-COM 2020 FREE 4 ALL
When using ocflash request interface isnt doing anything. Ive tried flashing bootloader and automatic but nothing works. I've since downloaded a few more newer firmwares but still nothing works. I've had more luck in the past with the clones but my genuine tool isnt responding. Any other way to recover? Maybe im doing something wrong
