Water pump replacement guide on Nissan Leaf 2013 - P31E9 error code

[cober]

Hi everyone!
I replaced bad water pump on my Nissan Leaf 2013 AZE0 and made detailed video.
I hope it's gonna help somebody.
Problem was - P31E9 error code EVC-314
I ordered replacement part from russian junkjard in Vladivostok (near Japan) and it cost me only 50$.
Did the job by myself in a cold garage couple days ago.
Enjoy the vid!

I got the P31E8-00 code and the charging would stop half way through the processing on my 2016 Leaf. I put my hand on the pump and it was not running with the car turned on or on charger. It had been replaced with a used one from a scrapyard, (it had numbers painted on it). I unhooked the wiring and pulled the rubber off the bracket pulling it up where I could jumper pins 1 and 2 and the pump started running. I put everything back in place and for awhile no code. It didn't feel like it was as strong as in my 2012 Leaf with two pumps. so I ordered a new one with the manufacturer number of the pump. It worked fine for awhile and feels like it is flowing more coolant now but I am getting the code again. The charging is doing fine with the new pump. I am now suspecting the harness has been damaged and will have to replace the harness plug.
