GetSKC Beetle cluster

[fktbnd]

Hello!

I have tried the getSKC command on my New Beetle, and I get this:

Do you have a solution for Get the SKC? The cluster is made by MagnetiMarelli, main chip :Motorola 1F68K

Looks like I broke something in version 0.72 (I did a lot of internal reorganization). Try version 0.71 for now.

Thank for your support!

Maybe this helps:

Well, it looks like you were able to retrieve an EEPROM dump. However, the data in the dump looks a bit different from other Beetle dumps I've worked with. Do you know whether this car is Immobilizer version 2 or 3? If it's version 3, then you should try DumpMarelliMem 14336 2048 and see if that works.

Based on the dump you shared, the SKC might be 29622 or 04120, but I'm not sure.

[fktbnd]

Its built in 1998, first gen immo2. I think the cluster was changed by the previus owner, because the date stickers on cluster are younger than the car. I tried 14336 2048 with no luck. I will try the 2 SKC, thanks. Is there a way to get a full dump from the cluster?

[fktbnd]

Unfortunately 29622 and 04120 dont work. I have run the DumpMarelliMem 3072 1024 command again, and some of the values are different (grey values on the picture). I think the two value what you mentioned from this "floating" area (0x0313-0x0314; 0x0348-0x0349). I have tried 09F6 (02550-62985) without luck. marellimem$0C00V2.log

[fktbnd]

I have looked some dumps from Beetles, and there are some with SKC at 0x0202-0x0203 big endian. Mine is at the same adress :). Thank you for your work, its a great program! Is there any way to modify the cluster temp light behaviour? It is switching off the blue cold engine light at 55°C and i would like to increase this value.

[gmenounos]

So your SKC is 02067? I can try to incorporate that SKC EEPROM location in a future version of kw1281test but first I'll need to figure out a way to determine whether the SKC is at 0x0202-0x203 or 0x313-0x314. Apparently, both locations are used by Immo2 Beetle clusters. Thanks for alerting me to the 0x0202 SKC location.

Unfortunately, I don't know if it's possible to adjust the cold engine light temperature.

[fktbnd]

The adress 0x0202-0x0203 is HEX 13 68 so the skc 04968. Am i wrong with the adresses? Is there a way to get the full eeprom?

[gmenounos]

Sorry, my mistake. I was looking at 0x0201-0x202. :-)
