I am considering having a Topdon Carpal as my OBD diagnostic tool. Has anyone on this forum had any experience of this model?

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?

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.

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?
