Cloned OP-COM v2010 - Big issue

[vanya86]

Hello to everyone.

I want to share my experience with you, because i import lot of tools and now i have notices something very strange for me.

I ordered 2 last orders OP-COM, but when i tried on PIN 12 to access some modules i had problem.

I will attach picture of PCB of new opcom, and that is new big sh*t product of china factory.
Every time if you order OP-COM ask your seller if possible to get old version of OP-com diferent from this one from my picture.

If they don't have, than change seller.

What component is the 20 pin plcc package?
Some chineese security for coning the clones?

[cosmind]

confirmed. this type of op-com dont work on pin12

[Tom_x]

maybe not enough relay for multiplexer

old interface have 8 relay!

[vanya86]

On this one is 3 relay less. But this 20 pin plcc is digital relay like on VAG VCDS. Good known GAL16V.

I try to find where is problem, i think problem is in Software, KW82 protokol dont work.

Second problem might been that GAL16V, wrong dump inside.

3. prob might be drivers and ept file in ftdi, because this one is V3 and when you install device it says V2, WRONG

4. problem might be mistake in building PCB.

Dump inside 18f458 on old v2 and new v3 is not same.

Don't tray to flash it with old .hex

I have cracked PIC 18f458 and i have new one hex.

[cosmind]

how can we fix this issue???

[vanya86]

I don't know, i am analysing complete opcom to find solution.

For now i think problem is in PIC or DUMP

PIC= because they use cloned PIC not original Microchip

[cosmind]

see this http://peb.pl/4121059-post848.html

you can try to change R32 from 10k to 510ohm

[vanya86]

I will try it tomorrow, i have 10pcs OPCOM.

If ok i'll confirm. But still i think that problem is in DUMP or in Cloned MCU

[Tom_x]

On pin7 you can connect engine ECU?
On pin12 detect connection and lost communication or nothing? Try different interface type on settings menu, example C or D type interface,maybe working.

Please measure obd pin12 with ohm meter, where it connected on pcb. Which relay, where to wired.
I think all type of interface use same firmware, and software settings (A, B,C,D) use different command for multiplexer relays.

[vanya86]

Same happens when i change type of interface, no communication on pin 12, KW82 protocol.
I have 2 different firmware, and bootloader, and still same problem.

Pozdrav Vanja,

Can you send me two pictures from your first post to my email (info@kdijagnostika.hr). I do not have sufficient privileges to access images on this forum.

If they don't have, than change seller.

So that's why I can't connect to PIN 12?
Do you know any sellers who have old school op-coms?

BIG ISSUE???

[jonsson84]

What happens when you try to connect over pin12? Is it stuck on pin7, or no pin at all?

[danyh]

Have exactly the same problem...will try to replace that resistor.

[teckynou]

I confirm that changing R32 resistor by a 510Ohm works!!!


I found the schematics of the OPCOM here : Repair Op-com Hardware Procedure? (http://www.digital-kaos.co.uk/forums/f152/repair-op-com-hardware-procedure-156380/) in the HOW TO REPAIR OP-COM.rar (http://www.digital-kaos.co.uk/forums/attachments/f152/29140d1282738956-repair-op-com-hardware-procedure-how-repair-op-com.rar) file
or here : OP COM (http://www.digital-kaos.co.uk/forums/f152/op-com-157337/) (3rd link)

the schematics is for the "old style" opcom interface : more relays, and doesn't have the PLCC20 chip.
But the K-line is the same as the new style interface. We can see R3 is a 510Ohm R3 is the same as R32 in the new style PCB.

If you check the datasheet of the L9637D chip, the typical application also show a 510Ohm resistor !!!

I made this modification few mounth ago, and it works fine!

Here is my thread : http://www.digital-kaos.co.uk/forums/f152/opcom-unable-read-pin-12-a-178694/

Ok, I replaced R32 with 470ohm (didn't have 510ohm) and now connection over pin12 is working fine. Before that I've checked relays and they are all fine. Relays are: AGN200A03 which seams to be manufactured by Panasonic. Any ideas if I can keep 470ohm resistor and not put 510ohm instead?

Another thing...I can't get 'Special Functions' button enabled in any modul. I'm using 100219a software from the following address http://opcomforum.yolasite.com/software.php
Not sure if that is correct. What does the 'a' means in its name? What interface type should I set in op-com software?

Cheers!

[jonsson84]

What kind of equipment do you use when changing the resistor? I have a simple 15W solder iron but it is impossible to solder so small components with it.

[danyh]

I was using something like this:

hi

i have few opcom with faulty line 12, and it was relay 5v who swich 12 line .

I changed R32 resistor to 510Ohm and it works for me too

[vanya86]

Here you go, for opcom users.

New dump for OPCOM V3 yelow PCB.

Say Thanks :))))))

[plaurinc]

Hi, thanks for info.

[cosmind]

Here you go, for opcom users.

New dump for OPCOM V3 yelow PCB.

Say Thanks :))))))

this fw can work with op-com that have R32 10kb, or I need to change this resistor with 510ohm

[mattydr67]

That rezistor you must to change it if you like to work on pin 12
I changed theat rezistor to 510 and now it work on pin 12
The firmwear I suppose that it need to write it becasue this tool has 3 realys less and thats was exchanged with a GAL I suppose.
Please if anybody has schematic for this OpCom V3, share it.
Thanks
Good luck

Hi , I had trouble with OPCOM firmware 1.39 (without relays version)...after connect to car (K line) every works ok,but for example connected to Astra H (CAN line) appears message: Interface Communication Error..Test interface done , FUT done ...I make reflash PIC and compare HEX with good file...no difference ...ok I was more search why do not work properly and I find reason ... GAL16V8D after replaced from new one OPCOM works fine ,,.I was try read GAL but no success, probably is secured ..My question is ..Is who have dump from GAL 16v8??? Thx

[liviudiaconu]

Question: you reflash pic with same dump (read from pic BEFORE you have the problem) or with another dump, tha "classic" 1.39 for "8 relays"?

Try read dump from PIC and compare with what you have for "8 relays". If is the same, maybe gal is reflashed (but i don't know if is possible with 5 v, in circuit). If not, must reflash PIC with "5 relays" version. ATTN to config bits, too!!!!!!!

[liviudiaconu]

Here you go, for opcom users.

So, is for 5 relays?

I have compared with Fw1.39 for "8 relays" and is the same.

[keygargoil]

I don't know, i am analysing complete opcom to find solution.

For now i think problem is in PIC or DUMP

PIC= because they use cloned PIC not original Microchip

how can i match a set of clocks for a 2010 insignia the clocks are from a different car and they havnt got the original clocks they were stolen
