Extract 12 byte CS?

Post by langers2k »

Using the read pin function on a immo4 cluster, it gives the pin and 6/7 byte CS.

How can I get the full 12 byte CS to reuse keys when only replacing the cluster using Iscancar?

Watching the CAN traffic when reading the PIN/CS on a cluster running 06xx, it looks like bytes 8-12 of the CS are transferred. Not sure about byte 7 though.

Still, that suggests Iscancar has the data so just need to show it to the user.
