I have recently had the same problem on my NM35. My 4WD light was coming on after a few minutes of driving. This then turned into every time i started the car the 4WD light would be on. While the 4WD light is on the ATESSA is not active so it will be running in RWD. The problem end up being (after a long time troubleshooting) a relay located under the air filter. This relay controls the ATTESA pump. Without the pump no 4WD. This relay in not available threw Nissan anymore so i had to addapt a generic 40A relay. This has fixed the problem completly and 4WD light has not come on again and ATTESA is working perfectly. I have attached some schematics that helped me out. I hope this helps someone out as i spent ages figuring this out. Cheers
