Can connect OBDII but not ECM

[xtrail67]

Hi

I have a 2002 Nissan X-trail T30 with the 2.5l petrol engine. I have a connectivity issue, I can connect to the OBDII screen and see everything that is going on but when I want to connect to the ECM screen I can't connect.
I have a VAG KKL cable which was the recommended one to purchase when I emailed before.

Any hints on what I can do to connect? I'm trying to adjust the engine idle

Thanks

Try adjusting the "Ini Timer Offset" value under Settings->Communication. Try negative and positive values. This may help initiate comms.
