2011-2012: Some permanent fault codes on after battery upgrade about nissan-leaf-battery-upgrade

[maheshsachintha]

Received P31B9 code after install 30 kWh battery to ZE0. Why? In addition to that it shows full battery bars. But battery is 9 bar and SOH is 73%

@dalathegreat In addition to that, any difference between open source 2 port can bridge firmware and your selling 2 port can bridge??

[dalathegreat]

I created a new issue for the bars(#9), and added P31B9 COMMUNICATION ERROR to the known error codes for ZE0 in this issue

I do not sell any CAN bridges anymore!

I recently did a 2019 40kwh swap into a 2011 and have a bunch of these codes so this is really good info to know.
However, I also have P32DA-83 L-ION BAD CTLR and P3191-00 L-ION BAT CTLR Comm Err EVC-257. Not sure if this is another one that appears on ze0s.

The battery upgrade CAN bridge is meant for upgrades, not for installation with 24kWh battery.

Just upgraded 2012 Leaf from 24 to 30Kwh battery. Are getting EV fault and turtle mode /no power or throttle not responding. Max 35-40 km/h.. But cruise control can increase the speed though. Can't read any dtc.. Any suggestions?

[Oggioffshore]

Solved. User failure in leaf spy. Didn't know u had to check for service, dtc readout every time u start app.
