My 2021 Leaf Acenta is showing System fault on the screen. Pressing OK removes the message but there is an orange exclamation mark at top of screen. Any ideas as to what would be the fault?

good morning

Usually you would need to have a scan tool to scan the faults. There maybe a way to do this manually, but I dont have a leaf to test this on.

Sit in the driver seat (car OFF).

1. Press and hold the trip reset button on the dash.

2. While holding it, press the Power button twice (don’t press the brake).

3. Keep holding until the dash flashes and displays “DIAG” or icons.

4. Release the button.

5. Press the trip button again to scroll through system checks.

If you only see “---” or no data, you’ll need a scan tool for detailed fault codes.

Give that a go. But i am no expert so if you get no joy then have this inspected by a dealer.

please let us know the results and what it was.. may help other leaf owners

Cheers

Thanks for your support, Steve. I tried to replicate your instructions but I could not get the response on my Leaf no matter what buttons I pressed! One thing I did notice was the 12v battery (it's always the 12v battery!) was only reading 12v and any load such as interior light dropped it to less than 12. I have now put the vehicle on charge and notice that this also charges the 12v battery, now reading over 13v. Hoping this might be the answer. But if not the car is in warranty so will take it back to the dealer for them to fix.

usually when charging, whether on a charger or from an alternator it will usually sit in the 13v mark.
Interesting to that the interior light causes that surge, battery maybe weak for some reason, although 4 years is not that old. But stuff happens.

might be worth investing in a scan tool when the car comes out of warranty. As dealers charge so much money for such little work

There was I thinking a System Fault must be serious but after some delving into the reams of paper that make up the Leaf owners book, I find that it is nothing major after all. I think one of the radars giving blind spot protection must have failed because switching off all of these functions the warning has gone! I don't think I will bother to do anything about this as if there was one function I would consider completely uneccessary in a car it would be this. The electronics systems fitted in modern cars, to my mind , is ridiculous. I suppose it is all leading up to when the human driver is superfluous? I also wish Nissan would include a manual that is specific to the actual model to which is it issued it is very confusing to have a manual that has all the items fitted to all models and nothing to indicate what is not fitted to a particular car! I am considering purchasing one of those OBDs, the Topdon Carpal looks like a good contender but I could not find anything on their website to see if it can diagnose faults in a Nissan Leaf. Perhaps there is someone on this site that would know?
