Thanks very much rsibiza, i change 93C56 and programmed it and cable now is recognize over computer. But again after programmed with different dumps it says " Not plugged into the car" but is plugged and ignition on. I nearly sure that has something to do with GAL 16v8B, so I unsolder it put into PLCC 20DIP and into my old TOP854 programmer. But the problem is I can read GAL but I can't write .JED file into it because I'm getting some error. Do you have any idea why? Maybe I should use different file with different extension? Can you help me with this?
The another cable after programming and testing show me some message like:
K1 Line short to +12V
K2 Line OK.

I checked resistors with multimeter(I have hope that I check the right one, other wise please point me which resistors are from K1 Line) but they look fine, where could be the problem?

For "another cable" try ONLY to power it from a 12V source + on pin 16 and - on pin 4-5. Without pluggin into a car. If "K1 line short to +12V" appear again, the problem is in the interface, if not and appear K1 OK, the problem is in ypur car and is caused maybe by a "third party radio/cdplayer".
Unplug the radio and try again..

The problem is 100% with interface K1 Line short +12V, because I tested it on different cars and still to same message, as well to same error with external power supply.
Which resistors are from K1 Line?

680 ohm between +12V and Kline

I checked again those 2 680 ohm resistors and they looks ok, so why is short to +12v???

you have a faulty transistor

**easyobd** · 18th April, 2011, 04:06 PM

Can you tell me which one, I nearly check everything.
Do you know what is the problem with other cable- is it the GAL? And if it is why I can read it but can't program it, do I have wrong .JED file?

Couldn't also be the CAN Controller (MCP2515) or the CAN Transceiver (MCP2551)?

Regards.

try to program a new GAL device - in this way you will find out why you can not program now the GAL from interface.

fro the second one - could be also a diode - for sure it is an "active device" - see the bunch of transistors near to OBD plug.

Actually I need programmer for multiple purposes not only vcds cables (chiptuning, dash etc.), I have GQ-4x but it is missing atmega and gal chip support.
Right now I am looking for wellon VP280 or VP380

Chips I'm interested is:
27sf010 and similar
24c02 and similar
GAL*
Atmega162
87c257
etc.

Would be great to hear your suggestions and comments.

Hi, I fix the problem with GAL programming-it was something wrong with software, after reinstallation software now everything is working. But still can't fix my BL cable, with the GAL which was original programmed inside interface(see picture 1) I have message "Interface found - Not plugged into car" even it's plugged. If I program GAL with .jed file (see picture 2) which I found over here (Aminebot solution for RL cables) I have message "DEVICE NOT FOUND". What is wrong, maybe .JED file for BM cables has to be different??? Or is it something else???

Thanks very much Aminebot, you're really MASTER if VCDS cables, after when I checked faulty cable again I found the problem.
Cheers.
Can you give me more tips how to fix other cable???

Thanks for sharing how did you solve your problem.

Keep posting

Good luck

... I have a strange situation!
if I plug firs the interface into the car and after to the USB port I received "unknown device"

if I plug the interface first into USB port and after into the car I receive "Ross Tech bla bla" = means OK.

where should I look for the issue?

many thanks
