KESS V2 V2.15 is a very popular ECU tool and is probably the most advanced tool available today. My customers feedback some problems. Here are the FAQs about below:
Just about UART pinout / connections on RX KESS v2 and TX KESS v2 with USB adapters …It seems to have differences between the connections…
It means KESS V2 can’t read and write this type of ECU, ECUs on the same car model in different areas are sometimes encrypted in different ways, and therefore the tool cannot always work on the same car model.
I replaced chip and reset tokens, then get connection error “External exception EEFFACE” as following picture shows.
