Diga problem. BIG Problem

[lupu_sandu]

Hy guys (and girls),
I have Tacho Universal from China ver. 2008 January.
TACHO2008 version when power-up is displayed.
My problem is after some uses (10 or more) i cannot modify
Opel Dash (Astra G for example) to OBD2 anymore.

When modify dash to OBD2 use:
Opel>Astra>VDO Diagnostic or 2001 Diagnostic.
Then input new value (old value is not displayed)
When Diga start to modify show on bottom on screen version of dash.
But for me this will not work anymore.

I have same situation and change motherboard of diga, but this work a few weeks and then stopped.
Now i have same f*ucking annoying thing.
Rest of cars seems to do just fine.:banghead:
Anyone have one solution for this? Or some advice?

[z786]

the cars that you have adjusted, have they had an aftermarket stereo by any chance????

[lupu_sandu]

No. I know the issue.
Diga stop working on Opel cars by itself.

[PremierD]

No. I know the issue.
Diga stop working on Opel cars by itself.

What year is your Motor mate....?...Had 2004 Astra G.. in a week ago..Similar Problem....Cluster turned out..to be TRW ..not VDO..Just a thought..

[Babanovski]

with diga you can adjust some of the astra dash not all of them. on some need to be removed and program the eprom. iven if is vdo.

Never came across an Astra VDO cluster that would not change with Diga mate... (But I could be wrong)...

[lupu_sandu]

I know mate, but even is a TRW dash Diga show you TRW Version when try to change mileage.
But i talk about my dash, is a VDO.
Diga working just great last weak on him, and now stop working.
I think in mainboard defective, but 2 of them? :((

try to backup and erase the diga maybe is full and can make that problem

[wbogdan]

i try tomorow test it

[lupu_sandu]

I try everything. I change dumps, i change chips from CPU board. :(
I order a new mainboard (blue version) - 90$ from China.
I hope 3-rd will be a lucky number :D

[cammy25]

problem is your adapter mate obd-k. look if there are some resistors or just cables.
If yor board is defective then you should exchange only 74hc04. This one is responsible for K-Line communication.
If you problem is in CPU board,then exchange the 2 74hc244.
believe me ,should be ok.
I have reversed Diga hardware long time ago. I have several solutions for it.

[lupu_sandu]

Cable is OK, i tested.
I have change 74HC5410 below display (near NEC processor). Same shit.
Ideea is after changing mainboard it's OK. I guess that CPU board is ok.

[Maxpower50]

i got tha manual instruktion for repair the Tachopro 2008 if intrested

[lupu_sandu]

Yes please.

[cammy25]

The HC541 you changed is for serial comm. for K-line you must change HC04 the SIOC14.
use philips D TTLs

[lupu_sandu]

Noted. I talk with one friend, and i wait now 4 HC04.
I hope this will fix the problem

[cammy25]

Unfortunately you dont live in the neighbourhood :ciao:
I have a reel of 1400 pieces of those things here:viking:

if you need any answers about Diga software or hardware just ask.

[mikac]

Hi . if i can get any information , about repair original Diga. Diga do not have comunication with PC. Is enybody know anything about???:help:
Thank's

[lupu_sandu]

What software did you use to donwload dumps? I use Tachodump and working just great. You must use a crossover PC serial cable, not a normal one.

[z786]

if you need any answers about Diga software or hardware just ask.

Hi, i have a diga clone 2008 with sync and update handheld problem, can you supply any dumps so it works like the new never locking one???

Thankyou

[lupu_sandu]

z786: Please read this thread:
http://www.digital-kaos.co.uk/forums/f104/tacho-universal-sync-error-48206/index2.html
I posted here dumps from Diga.

[cammy25]

The serial problem is not in the serial driver on the motherboard. Its a faulty CPU ( YES I MEAN 386EX) somehow the TX and RX inputs are blown up.
change CPU and serial comm will work.

[bbenk]

hey cammy25,

I have the clone, some adapters have no amp like the E36 and the golf 3 how can i connect them?

[lupu_sandu]

Good luck.

[mikac]

Do you have a switch on your board? if yes ,then change positions. Or study the cable shematics.
If you can write you can read. As simple as that.

[cammy25]

Try to resolder all solder joints (soldeerpunten) near the relay on you motherboard.
Or your relay stay hanging on NC.
Sometimes the relay will click if you slam your diga with your hand (no joke).
This problem is called: Chinese shitty soldering techniques.

The relay on the motherboard has bad soldering! strengthens soldering on the relay! I had the same problem

I have same problem, But I never has successful change
I have tried in renault megane 2003 (93c56)

What I can do for correct this??

[drpeter]

Cable is OK, i tested.
I have change 74HC5410 below display (near NEC processor). Same shit.

If OBD2 is not working, the small SMD power transistor is defect, left under lCD screen (I think it was a NPN transistor, check number) I took a normal BD137 for this, not sure long time ago. Measure between 2 legs, if shortcut then transistor defect. If not replace the 74HC04D above the transistor. Once I had a transistor defect and on another diga the 74HC04D.

Hi m8.

Could you please be more clear? You wanna write 93xx?
What dash? Make car?year?

Do the manual show that diga should show old km? If yes,and diga does not show actual value,dont touch.

Diga shows old value,change.

Regards.

[Rito]

For example in renault clio or megane my diga says: (general faul read)

I can?t read any 93Cxx of course can?t write.

I see in this web site which have solution for this problem.

Today I have met the same problem!
In the past ...even Diag / TU not shows the current value... under the new value after pressing OK button...should appear version (TRW or xx203 if VDO) but now nothing even if it's VDO!
Any solution for this problem or I have to buy a new TU for Opel by OBD?!
Many thanks in advance!!!
