kw1281test: A Free VDS-Pro / VagTacho Alternative

[pkhoury]

Oh right - now that you mention your other side-project, I remember that the pairing process also writes the car's VIN to the cluster; so at the very least, that would have to get over-written as well. Given the 17 characters of the VIN, and it appearing at least a couple times in the EEPROM, going the VCDS route will certainly be easier (....well, until we see what your next/new app can do. ).

For what it's worth, I would just edit the dump manually in XVI32, but I think Greg's unreleased software option would end up being more useful.
Some of the niceties I have on my clusters are needle sweep, cruise control light on only when cruise control is activated, and you can change what's lit up on the cluster, regardless of how the light switch is turned to.

I don't think it's that simple, but give it a try and report back whether it worked or not.

I have another program I wrote that can toggle on/off a few of the cluster options as well as transfer the odometer, SKC, Immo ID, VIN and radio pairing from an old cluster to a new one, but I haven't made it publicly available yet.

Now you need a name for these tools. GregTools? GregSuite? Yeah, I'm not that creative on naming things.

Yeah - that's what I've been doing. I'm a Mac guy, though, so my go-to is iHex.app.

Definitely interested in GregModder™ v2.0 has in store as well.

GregModder is catchy. I guess it's up to Greg to choose a name though, right?

What's iHex? I'm technically a UNIX guy, but never cared much for Macs.

 

[Nuje]

I'd googled what VXI32 was and saw that it was hex editor; iHex is just same thing for macOS (available on the Mac App Store).

Hi Guys, I ran into a problem while modifying my CCM Eeprom dump. I wanted to do the trunk "pops out" coding but if i modified the addresses, i couldn't open the trunk when the doors were unlocked, I could open it only with the FOB key and the interior switch. I wrote back the values and the trunk is fine. But... If I open the trunk, the display shows, that every door is open, except the hood and the driver's door. In the evening I noticed hat my interior lights are not working. Actually if I set the front dome light switch to 0 and I open a door, only my 2 rear lights are working. What could i miscode or what mistakes did I made to my CCM? Does anyone know the address for the interior lights? Hope I can get some help...
Thanks in advance.

I know very little about the various CCM mods. You might want to try posting here: https://forums.tdiclub.com/index.ph...ions-with-vds-pro.160960/page-19#post-3754759
It'd also be helpful if you could post exactly what commands you used to modify your CCM.

That being said Greg, if you don't have a disclaimer holding you harmless and the software being released AS-IS, I would suggest it.

 

[Nuje]

Agreed.
Probably get the best help if you say what you started with, what bytes you changed to what, etc.

Doing a "reset" on the CCM might help straighten things out - disconnect the negative battery terminal for a minute or so to let everything discharge. Plug it back in and see if that helps things out.

Isn't that, at the very least, implicitly agreed to when a person downloads from GitHub?

Thanks for your reply.
So:
Address/Old value/New value
04361/67/66
04362/67/66
04363/67/66
04352/33/97
04353/33/97
04354/33/97
First I'll do a "reset" on it, and tomorrow I'll compare my values with a "healthy" CCM, hope I'll get some ideas.

Thanks @Nuje , surprising but I disconnected the battery, and every function works normally again.

 

[pkhoury]

Ha, I didn't know we could do @UserName on here to refer to other users. It'll take time getting used to this new forum software!

On a note related to this thread, @bereczd, I remember at some point seeing a table that listed what each bit did when we changed values in the CCM. I don't remember what my value is now, but I think it was also 66 originally (but I could be mistaken). I originally had a problem, by just copying what I found on tdiclub, where when my back hatch was open, the rear wiper would engage. I've since fixed it, though.

Yes, I'm reading these forums for days now, I think I got the correct informations now. I'll give that a try again. Btw. I didn't have problems with my rear wiper,but I know it could've been confusing...

 

[ToxicDoc]

This thread needs to be stickied to the top along with the fan and air blend topics

 

[Nuje]

Thanks @Nuje , surprising but I disconnected the battery, and every function works normally again.

Always remember that these modules are really stupid, simple computers; sometimes a good reboot is the fix.

As for your coding issues, if you convert your original number to binary, you can see where you have ones and zeros.
e.g., 67 = 01000011

Earlier in this thread, @ekincaid took a spreadsheet I'd found (and loosely translated (Google) from another forum), fleshed it out a bit with examples using @gmenounos tool, and pdf'd it.

Here's the pdf'd sheet and his Excel sheet; quick screenshot below (click the image to embiggen):

 

[pkhoury]

Thanks @Nuje . I guess that's the one thing I forgot to enable - windows up and down with the remote. Thanks for posting the PDF/excel spreadsheet. And I concur @ToxicDoc about this being stickied - since we now have a virus-free way to do vagtacho/VDS-Pro functions that works with modern computers, this should be a must-have along with VCDS for the enthusiast!

 

[ekincaid]

Thanks @Nuje I was hoping that sheet would prove useful.

 

[Mozambiquer]

So far I've only used this for reading the skc on my car, but I would really like to have my hatch unlock when my doors are unlocked. If I understand correctly, I'd do this command

kw1281test.exe COM5 9600 46 WriteEeprom 04352 76
kw1281test.exe COM5 9600 46 WriteEeprom 04353 76
kw1281test.exe COM5 9600 46 WriteEeprom 04354 76

I would assume I would need to do those as separate commands? This would be on a 2001 golf btw

 

[Nuje]

You'd have to know what the current values are for addresses 04352, 04353, 04354.
If they're currently 200 (binary 11001000), then from the chart, that should change to 01001000 = 72

(Chart suggested 76 because one other bit was flipped to enable auto-unlock.)

I've seen all sorts of numbers for those addresses (not just 200): sometimes they were all 6, or 105, or 136, etc.

Ok, so I'll read those addresses and whatever is is, I change the bits in binary, then convert to decimal to write it into the ccm?

 

[Nuje]

That's my process. Of course, always take a photo or write down what you have initially so you have a way back.
(And make sure the car's battery is well-charged - having recently driven it should suffice; you don't want to be writing to a computer's memory with its power supply being flaky.)

 

[bereczd]

So, it's me again.. trunk works perfectly now, but I have another thing to think about... When I unlock the car, or pull out the key from the igniton, the interior lights come up only for a moment and then go off. If I open a door, it lights up normally, but when i close the door it turns off immediately (does not remain like 10-15 seconds and not slowly goes out when the ingition is on).Does anyone know about something? Anyway, it's not a big problem for me, but i want to find the way to correct it, but at least it's special, not like the other cars, but interesting...

 

[Mozambiquer]

When I read the Eeprom, each spot had the same value, 255, or in binary 11111111
That doesn't make sense to me. I tried to modify and write the Eeprom, but it would not allow that either.

 

[Nuje]

Something didn't work properly. 255 = FF in hex, which is basically the same as "empty".

Try it again, verify connection; verify you have sufficient voltage (+12.5V is recommended by Ross-Tech for reading and writing modules).

Interesting. I had plenty of voltage, and actually had a charger hooked up to make sure of that. I'll have to play a bit more with it tomorrow, since I've run out of time for today. I may try with the other computer as well.

What is the part number of your CCM? If the part number starts with 1J0 then the above info might not apply to you as it's for 1C0 CCMs.

I'll check that tomorrow. Is there a different procedure for the 1jo CCM, or will it not work at all?

 

[gmenounos]

It's probably a different address and/or value for 1J0 CCMs. Both of my cars have 1J0 CCMs and I've only done the window mod. I'd love to find out details of the hatch unlock mod for both.

Hey There. Just used your software for the first time tonight on my cousins 2004 GLI 24v VR and was able to write the comfort windows via keyfob coding to his 1C0 CCM. I still have to try pulling his SKU from his cluster (since he needs another key).

As for your requested 1J0 addresses for unlock hatch with doors, I believe it is located at:

J: 04283, 04288, 04293: Bit 7 (1=Off, 0=On)
AJ/AH: 04280, 04286, 04292: Bit 7 (1=Off, 0=On)

Neither are confirmed but might be a good start. I've been building a large excel file with known bits but I have not been able to confirm anything.

Anything else you want me to share with you that you can use to confirm on your 1J0 CCMs?
