Nissan Leaf won’t start or charge

Hi all have Nissan Leaf 2012 plate
Brought two months ago was up and running , but was unable to charge by home charger or granny charger ,
Charged at local dc charger ok.
Leaf has stopped starting going into drive or reverse , showing various brake faults
But main fault I am trying to clear is P31e0. High voltage circuit interlock fault ,
Also battery meter displays 3 dash’s . But when I clear dtc on leaf spy mileage reappears until ignition is switch off , then on again ? Any help please

I assume that you checked the rest voltage of the 12 volt battery? What was it?

Hi thanks for your reply
Battery is new replacement . Voltage is 12.97 standing
You don’t hear any main traction battery contacts switching on.when powering up ?

I don't think you should normally hear the main contactors. There is a semi-common failure of a diode that produces the symptom of only charging on DCFC, but I don't remember it producing all those other errors. It can be fixed by replacing the diode. I'll look for the topic...

Here are two topics on the subject:
