This is an old quote but it was the clue I needed to get a charge graph on my new 2019 SL Plus. I'm using iOS LeafSpy Pro v1.7.38 and an LELink 2 dongle. With the car off, initial attempts to monitor a charge gave an intermittent graph, with green, yellow, and orange connection status indications. Relay clicking could be heard from the rear of the car every few seconds. If I opened the car door I would get green status and a short run of data. In accessory mode, I got green status and good charging data for about 30 minutes until the car shut itself off. Re-enabling accessory continued the data acquisition.Turbo3 wrote:For the older Leafs you could graph charging without the Leaf being on. For the newer ones things have changed. I think on one new one I tested you needed to have the Leaf full on first to get the graph going and then you could turn the Leaf off. You also might be able to start a graph if you start charging just after you turn your Leaf off. The key is that the VCM ECU still needs to be awake to get the data from the battery controller. The VCM is the bridge between the CAR CAN bus the OBDII Adapter is plugged into and the EV CAN bus the battery controller is on.donyjunk wrote:Maybe since I've been on vacation it's been too long since I last used it, but does the car need to be fully on for Leafspy to record charging? I coulda sworn I used to be able to get a charge graph while in accessory mode (one power button press, without brake pressed). Now it seems to only log if I do second press of power button ( brake off).
I assume this is normal due to the VCM ECU state. My suggestion is that the LeafSpy help file be updated to describe this behavior.
