Ref No. FAQ-A9a
Some Nissan ECUs stop responding after trying to connect using the wrong protocol. Cars with such units must be connected immediately via Nissan protocols, without trying to connect via OBDII / EOBD protocols before.
- If automatic connection to the car is enabled, temporarily turn it off.
- Create a profile of your car (or edit an already created one) by selecting in the “Diagnostic protocol” – “For Nissan” item.
- With the ignition off, connect the adapter to the diagnostic socket, turn on the ignition (engine).
- Connect to the car using Nissan protocols.
