Query/response 71e/72e, 71d/72d

Thu Jun 16, 2016 7:21 am

I've been logging the CAN traffic on my 2015 Leaf for a while and looking for rare events, I noticed some interesting transactions which only ever occur on the CAR bus just as charging begins. It looks like there are a couple of active queries initiated by the car itself from 71e and 71d with responses on 72e and 72d respectively. I haven't seen any discussion on these before (and they aren't on TickTock's magnificent spreadsheet). Has anyone else captured these or had a go at decoding the data?

Here is a typical sequence from the log; I've indented the data columns to help show the request/response pattern better:

Code: Select all

                                (71E)           (72E)           (71D)           (72D)
