SLS question again !

Ok put a 2 inch lift on my d2 with air been fine until I had the suspension levelled off now the pump doesn't come on like it did and come the morning the n/s has dropped checked all the fuses fine new level sensors fitted weeks ago , also if you try to lift it on the switch to off road mode push the button let go and it gos off straight away .... Now the pump works to inflate the bags when a diagnostics is put on to calibrate the sls my question is can the ECU be disabled for the sls ? Oh and all the doors where. Shut too
