Digiprog 3 CAN solution

**autocentarvu** · 22nd May, 2016, 07:58 PM

Hi!

I have bought clone Digiprog 3 V4.94 and it worked like a charm. Everything worked (on OBD2) K-line, K CAN (BMW), CAN. I didn't care about EEPROM, MCU programming because I use other tools for that.
All readed KM where good like if it is on dash 123000 Digi reads 123000 I was wreally satisfied.
BUT, one day by my mistake I gave 32V to Digi and he died (OBD2 cable was not pluged in). There was short cirquit between + and GND. I find few broken parts and have change them.
Digi starts and K line works without problems K CAN also works but not reading KM good any more for example dash 123000 Digi reads 75692. CAN not working at all allways NO CONNECTION.
I have changed AU5790, TJA1054, 82C250, MAX485, check OBD2 (from PCB board to inside OBD2), check all relays, check all other components like transistors, resistors...
I can hear relays clicking when I choose CAN based car but NO CONNECTION.
Few days ago I need to make one A4 B7 2009 year, offcourse NO CONNECTION but I have find that rx and tx for 82C250 going from/trough GAL22V10D. CAN (for this car goes directly from 82C250).
I have found few dumps for GAL but neither one is working.

So if someone have good/tested dump for GAL please send it or sell me programmed GAL.
Do you know does this GAL have programming fuses? on my programmer is only Vector (I'm not so familiar with GALs).

I also try to program new software in two 29F800 but no luck.

Thanks in advance

Best regards

You better buy another box. Its cheaper then spending hours on repairing the board.
