E51 Elgrand Trouble Finding ECU's
Posted: 25 Nov 2025, 09:21
Hi all,
I'm new to JDM cars and trying to diagnose a non starting E51 Elgrand (cut out suddenly when driving), I'm pretty sure it's a crank or cam sensor as it won't fire on easy-start and isn't sparking. Tried fuses and relays already etc. Problem is I can't get any fault codes or live data from it as it won't connect to NDS2 properly, the only ECU it will find is SRS (58). I have tried changing app permissions, com port numbers, Ini Timer Offset, cables and also reinstalled the app. I'm stumped, I think I'm doing everything right, especially as it will connect to the SRS ECU fine. I've seen other people online using NDS2 on E51's as well. Don't want to start throwing sensors at the car without any information.
Suggestions welcomed and thank you in advance for any help
