@isak Now that I know what is shown on the OLED is an error code...this code is "Caution lamp and Charging stop" From the Owners Manual: These are all errors directly from the Nissan Leaf BMS, they are quite explanatory and should also be corrected immediately. A good solution to locate the error is to use Leafspy
and look for the errors the BMS experiences. One cause for the caution lamp and charge
stop error could be a disconnected BMS balancing wire. This will cause the bms to not allow
charging of the battery and limit the motor to 4.5kW of power.
It is recommended to use a bluetooth dongle and to connect Leafspy to your car for specific
diagnostics and to see the health of your battery.

The LELink bluetooth OBD dongle came with my kit. Doesn't look like I can access it because I don't own an Apple product.

Is Leafspy an app or another piece of hardware?

This is the document that came with the LELink dongle with my kit. There is nothing in it that says to connect to Leafspy.

Leafspy shows no DTC codes. Now the project is stalled until someone can help me diagnose what needs to be corrected.

Posting the multimeter readings from all 3 battery packs.

And here's the OLED display.

As you can read in the Owners manual linked here: https://resolve-ev.com/pdfs/owners_manual.pdf

This is a "warning light" signal from the BMS I would recommend updating the Resolve controller to the latest software update here: https://resolve-ev.com/update
If that does not solve it I would try to troubleshoot if something is connected wrong to or from the BMS

@isak I was able to update the software, although I tried updating to 3.7, Console shows 3.5. Data doesn't appear to show anything even with connection. Connecting Ignition to 12v causes a "waiting for data" message that doesn't end.

leshall89

Not sure how BMS could be connected wrong considering all connections have only one specific port they fit into the BMS.

@isak Sure would be nice to get some feedback for all the emails I've sent you trying to figure out the problem why this won't work...

I just realized Leafspy isn't connecting with the LeLink dongle so the picture 20 days ago isn't actually showing anything from my system since the lower right hand corner isn't green. Still can't get Leafspy to connect to LeLink, I think this might actually be a problem with the Resolve system...what do you think @isak?

Hi!
I would recommend being concise in your emails and not sending 14 emails in the span of 2h. It does not really make it easier for me to help you. To focus on what I think the issue is and as I wrote to you via email. The last console log you sent showed that the leaf BMS think's the packs voltage is 511V which i suspect is due to the voltage sensor is disconnected or not functioning properly. I would focus on solving that
