Yeah, this is shaping up to be a case of either a bad charger or a disconnected line. Earlier, you posted the DTCs that come from the car, here:
Is that still right? I'll break them down here. These codes seem to be for a 2013+ model LEAF, so this is from the 2013 info:
P3177 - ECU ACTIVATION ERROR (EV system start error) - looks like a general error. Any system can be a cause.
P3171 - PD MODULE SYSTEM (Power Delivery module system) - This is a general error saying that the PDM has an error in its system.
P3170 - Also PD MODULE SYSTEM - general error.
P316C - Has some interesting info, but also seems like a general error. It ties in with P3177.
B26C1 - I spent a very long time trying to figure this one out, but couldn't find it anywhere in the manuals or online. However, if it's B29C1 (see below), then it refers to a whole host of EVSE (charging station, not internal) errors. In fact, this is where the story gets good... because the symptoms you describe are similar to how the Leaf behaves when it's not able to properly start charging normally due to external factors - for example, if I have an AC line of an EVSE disconnected, yet the EVSE keeps signalling "you can charge, go ahead", the car will stop after 2 minutes and set a similar set of faults.
Now, here's where it gets good. Assuming that the B26C1 DTC is really B29C1, then Nissan has a present for you.http://x.nissanhelp.com/forums/local_li ... &catid=783

That service bulletin nails your symptoms to a "T". You've got the codes, and the symptoms, that they describe there.
IF YOU CONFIRM:
The customer states the HV battery charger of an applied vehicle will not charge or will not complete charging
The EV warning light is on and all of the following DTCs are found stored:
• P316C, P3170, P3171, and B29C1
NOTE: CONSULT III plus must display B29C1 with malfunction type “EVSE no signal” or “EVSE invalid signal”.
The only question is, do you have anyone around with a "CONSULT III Plus" unit? I'd imagine that pretty much anyone that works professionally with Nissan cars should have one... not a shade-tree mechanic that works on carburetors, but one that isn't afraid of a Nissan made in the past decade. They should be able to follow the directions right out of that bulletin and apply the fix.
