VitaminJ wrote:Why would you wait until it's working to disconnect the 12v battery? The idea is to disconnect the 12v to make it start working. In your case it's probably worth it as your unit is working from the car out, but not from outside to the car. Also the EV warning lights your describing is classic weak 12v, which causes the TCU to go into standby.
I already disconnected the 12 volt weeks for ago to see I could get it working. It didn't help. See viewtopic.php?p=491430#p491430.
As for "classic weak 12v" causing the EV warning light, I doubt it. I charge up my 12 volt w/an my Tecmate Optimate 4 every now and then, often every week or two.
I think it's pointless to disconnect the 12 volt at this point when the EV support folks called me yesterday telling me the process is NOT complete on their end yet and to wait until Wednesday.
edit: 12 volt charged on my Optimate 4 overnight last night. Disconnected this 12 volt charger this morning. Received my first "Nissan LEAF update: Charging Stopped" at 1:30 pm Pacific that I've seen since the shutdown and upgrade to 3G TCU. Nissan Connect iOS app status check w/valid GOM values worked at 1:39 pm.
No warning lights after unplugging (still using the 80% midnight to midnight timer trick) but these time, I left my Panlong OBD2 dongle unplugged, for good measure.
Still no phone call from EV support folks.
