GreenaGiant said:Yeah the 12V battery was knackered. I have replaced that now along with the relay but still have those issues.
GreenaGiant said:So the pain isn't over.
Car is still being a pain and refusing to work properly. Mainly turning off is impossible without removing the ignition relay then pressing the power button.
Getting the car into ready mode is also about 1:100 luck. So I think there's a deeper problem. I've just tested the ignition relay and it is completely fine.
I've done a LeafSpy read of the Dates, if anyone can point me in the right direction to a diagnosis I'd be eternally grateful.

GreenaGiant said:The relay I gave a good test and it was fine right down to write a low voltage. I forget the exact number but it was around 6V. So I'm happy the ignition relay replacement is fine.

It is possible the electronics (modules) need to be working with a relay which has whatever the H91 stands for. We don't know if the H91 code is for the amount of current the the relay is pulling while closed or during inrush or something else. There is a resistor in some of these relays which is probably intended to slow inrush.

found parasitic drain of .37A
traced clicking noise to ipdm clicking on and off
found pin 35 (vcm) getting 12v feed
checked for water ingress no signs found
checked for earth at pin 41 and found no earth
relay still clicking
expect internal fault with ipdm - requires replacement, further charge and test

GreenaGiant did you solve your issue? It seems to be the exact same as my issue - nissan diagnosed a 0.37A draw, recommended and IPDM change (for £900!!) I did it myself but still have the same issue (relay clicking from inside the IPDM) alongside a couple of miscellaneous things like my DRL being dim etc
Excerpt from the nissan report:
found parasitic drain of .37A
traced clicking noise to ipdm clicking on and off
found pin 35 (vcm) getting 12v feed
checked for water ingress no signs found
checked for earth at pin 41 and found no earth

I make an assumption here that no earth at pin 41 is a good thing (based on the report)
(I'll double check if the fuse pull works for me, but my car is currently dead - not even clicking so I'll need to boost it and deal with it at the weekend) - I expect this fuse pull will work for me as everything else was identical (I also had i-key system faults etc, have since swapped the 12v) - have you checked the fuses inside the cabin btw? That's on my list to check as well
