TT 8N1920930J M73 D56 timeout

[danolsn]

I am able to connect to the ECM but I can't pull SKC. I get the sense that these TT clusters vary wildly.

Did you only try once or do you get consistent timeouts? Can you connect to other modules in the car? What kind of cable are you using?

[danolsn]

I tried several times. I also tried DumpMarelliMem which made the cluster reboot/reset the clock/date. I was able to connect to the ECM ReadIdent which I found as a suggestion in another thread. I am using a cheap VIMVIP VAG-COM KKL cable. I have a hex-net that I could try if these interfaces work

The cheap cable can communicate using VCDS lite. I can try again tomorrow

[gmenounos]

Hex-net isn't compatible with kw1281test. Can VCDS lite connect to the cluster? If it also times out then you may need to disconnect the battery from the car for a minute and then reconnect to reset the cluster. The GetSKC command can leave TT clusters in a bad state sometimes. Also, 9600 is the usual baud rate for TT clusters. Try 9600 after disconnecting/reconnecting the battery.

I am able to connect to the cluster with my cable using VCDS lite. I will try what you recommend later tonight. I assumed the hex-net would be too "smart" for this use. I was looking all over the internet for similar situations using your (seriously awesome) project, so I tried many things but I did not think of disconnecting power

[danolsn]

I made it a little further after disconnecting the battery for a few minutes
