Thanks for the replies.
The procedures as reported in
my post are straight from the horses mouth of the Nissan Leaf Service and Repair Manual. The procedure is straightforward and I will be following it.
My concern was to get some practical info from others of their experience of the potential effects of the disconnection, albeit a very brief disconnection, when swaping the old battery for a new one. So far no real scare story has emerged, regarding the list of items mentioned in the manual at PG86 requiring "special repair requirements" when removing 12V battery Negative terminal. My Nissan Leaf has the heat pump so I just pulled out the elements relating to this in the Heater/Air conditioning control system section below.
Any further contributions welcome.
To recap.

Reset electronic systems as necessary. Refer to PG-86, "Special Repair Requirement"
So I wonder what PG86 has in store......this together with links to other sections of the manual with detailed procedures for the items mentioned.
