Post a 100% charge last night that I need now to go distances that 80% was good enough for two years ago, I drove off his morning and about 2km down the road I had these warning lights on. I stopped the car and switched off. When I switched on the light was gone, so I drove off and then 1km further it came back on, I returned to home and grabbed the large 4wd ice for the trip. When I got home a few hours later, I pressed on, it came up no warnings, then within 2 mins the light came on again and the sound of maybe a pump under the bonnet that I hadn't heard before. Hence to say I have left it in the garage and will call nissan in the morning. Any ideas out there, has anyone had similar? Cheers

Could it be your coolant level? Got an OBDII dongle to read the error code?

Cheers Hi stewartm Your right hand picture is showing the yellow master warning on the upper display, which is just telling you a yellow warning light is showing on the lower display. The left hand picture shows the actual yellow warning, which appears from the manual to be the EV system warning light, indicating a malfunction in one of: Traction motor / Inverter Charge port or charger Li-ion battery system Cooling system Shift control system Emergency shutoff system is activated You need the code(s) to tell, but your pump noise could well be a cooling system fault. Off to Nissan I'm afraid...

Did that on Sunday, they sent RACQ roadside assist, guy said he had never seen an EV and nothing he could do. It was towed this morning to the Service agent 100km away. Hoping its not major as I am a car short..

Sorry its a bit late to mention now, but the leaf spy app would have told you what the exact error code is. Having said that, since it seems to be EV charging related there was probably nothing you could do about it anyway.
I would expect a loan car from the Dealer, they took your money when you bought the car and in return you should receive a working car for at least 3 years under their warranty.

Thanks Duncan, I have bought three Bluetooth ODB adapters now, to no avail as none worked even though they said they were compatible.
The fault was a broken coolant pump, took about 10 days from Japan, but fixed now. Thanks to Dean for arranging a hire car for the period and his support on a National basis.

Thanks Duncan, I have bought three Bluetooth ODB adapters now, to no avail as none worked even though they said they were compatible. Hi Stewart After 3 adapters that didn't work for you, I would image you don't have much (any) appetite for a further purchase BUT if you ever decide to, I recommend trying the adapters that Turbo3, the Leaf Spy developer, is currently using. You can find this out on the MyNissanLeaf.com forum, where all the development of LeafSpy is discussed in the Leaf CANBus subforum under Accessories / Mods. You will find: the thread iOS Version of Leaf Spy development discussion (iPhone etc) and the thread iOS LeafSpy Pro Support (also iPhone) and the thread Leaf Spy and Leaf Spy Pro (android) I usually start with the latest posts and work backwards; someone is always asking for a recommendation, or giving feedback on an adapter purchase. You may end up paying a bit more, but so many cheap adapters are incompatible, and these ones work for Turbo3.

I borrowed Jeff's (jcan) Konwei KW902 while I was visiting on my recent excursion through the Blue Mountains. It worked first go in my LEAF so I ordered one straight away from ebay (about $30). Now working 100% (Android LEAF Spy) and I love all the numbers:-).

They also did the software update. Can't see any difference yet, seems the same. Still 11/12 bars capacity and 132 available on full charge.

I had a warning light come on last night. It was after a fast charge at Donnybrook. I figured it was the same problem that I had a month or so ago after a fast charge so I was happy to drive on. But I had a last look around my LEAF Spy readings and noticed that the battery temperature bar graphs were showing one (of 4) packs was very high (and coloured red). A couple of "system resets" with the on/off button did not help to get rid of the warning light.
The value on the graph was 37.6°C which I figured was high enough to give me a warning light. The dash display of battery temperature was a nice safe 6 bars. But the LEAF Spy showed 4 bars on the graph and the hottie was 37.6° and the coldest was 28.2° so, on average, the 6 dash display bars were probably as expected.
I sat around for 30mins (around 8pm) and watched the temperature of the hot pack drop by 0.1° over about half an hour. So I headed off from Donnybrook to Collie (my destination) at a sedate 65k/h and watched the temperature drop to 34° as I drove 'home'.
This morning, it would not start a charge on the EVSE. So I did another "system reset" or two with no result. I then disconnected the negative terminal of the 12V battery for 10 seconds (as I did last time) and the warning light went away and the EVSE charge started. A slight spark reconnecting the negative terminal caused me a minor concern:-).
So..., I think maybe the first time this happened a month or so ago, the battery temperature could have also caused the warning light and subsequent refusal to EVSE charge. On that occasion as well as yesterday's trip from Collie to Donnybrook to Nannup to Margaret River to Nannup to Donnybrook and back to Collie with all those fast charges at each town, and driving in between charges, is too much for the battery pack which I believe is neither water or forced air cooled.
It would be nice if there was a more elegant way to reset the master computer:-).
PS. I just looked at an earlier LEAF Spy battery temperature graph (from 100km earlier) and it was 39°C and that did not cause a warning light, so back to the drawing board with this one.

I thought it was winter - what is the ambient temperature where you are, for heaven's sake! There are plenty of Leaf forum posts on vague/unusual symptoms being traced back to the 12-volt battery, and if your HV battery is displaying such high temperatures then it is not all down to charging and driving; the ambient conditions will be hard on your 12-volt battery as well. Are you able to test it? (even just to discount the possibility)...

Minimum daily temperatures are minus 1C to 10C and maximums don't quite crack 20C. I did read a lot on the 'Net when I had the first occurrence and apparently it happens a fair bit after a fast charge. I will keep an eye on it and report it to Nissan. I do have LEAF Spy Pro but I did not see an error code but I was not looking for it at the time).

My reading of the Net plus the car handbook suggests to me that your Leaf is responding normally to heavy use. When the EVSE won't charge, have you looked at the sensor temps at that point? Even overnight, your pack temperature might not drop enough to allow charging.
It seems to me your "system resets" might well be bypassing a "failsafe" condition, with unknown consequences, but certainly including the possibility of cell failure.
Good luck!

Temperatures back to normal after a 100% charge overnight. Temps were 16.2C/14.3/1.9 (max/min/diff). Ambient 8C. Battery cells 4.079/4.088/4.102 (min/avg/max) (max diff 23mV) I did check with Nissan LEAF service guru at Moorooka Nissan before the power off reset a month or so ago and got the ok to go ahead.

My record so far is only 8-bar (travelling down South West of WA with QC all the way in summer). Thanks for the link hieronymous. It lets me sleep a little easier with my (much) cooler 39C. Looks like my warning light was probably the interface between the DCFC and the LEAF.

My EV warning light comes on when the Leaf completes a charge at 80 or 100%. No warning light if I interrupt the charging. No problems with charging or driving. Booked in at Nissan for this Friday. Probably should get a dongle so I can see what is going on with LeafSpy.

Everything is back to normal. No more EV warning light after charging. App works perfectly. What the hell?

Hi Jake, I had similar issues with my Leaf, turned out to be low charge in the 12 volt battery. When topped up with a smart charger, no issues. Ended up replacing the 12v battery, was almost 5 years old which is marginal for a standard lead acid battery. Just a thought.

Thanks Stewart, That will be something I check if it comes on again. Just got back from the dealer and they checked the codes. They were all TCU errors which is a bit of a worry considering that has just been replaced although everything is working fine now. The TCU was unable to communicate state of charge which explains why the mobile app was only partially working for me. I had no idea that the TCU could cause a warning light. Anyway all good for now, I have just been told to monitor the situation.

The EV warning light is on again when I jump into the car after charging. I gather it is TCU errors again. The car can't communicate that the charge has been completed. Can't get state of charge or turn on the climate control from the app or portal. However all driving data is successfully being uploaded. Partially working TCU! Very weird. Back to the dealer on Friday.

Everything has fixed itself again!!? I have a theory but it seems dubious. Does anyone know what happens if the car is out of range, and while plugged in, tries to communicate that charging is complete? Will that cause an EV warning light, and prevent the app from getting state of charge and controlling climate control? I wouldn't mind not getting notifications at home now and then. I am in a valley and it can be a mobile black spot. What I hate is after communication fails it stops me being able to control the climate control with the app. I also have a theory that a couple of logins using the portal may help fix the situation. More experimentation needed. I cancelled the trip to the dealer as I didn't think there would be much they could do if everything is working at the moment. I have a feeling 2G was more reliable in my area than 3G and that is why I didn't have the problem before.

Ok I have figured this out. I get a warning light when the TCU can connect but then is not able to transmit the data it needs to. (I have intermittent 3G coverage at home). This also stores an error message on CarWings which stops the mobile app from receiving a battery status and controlling climate control. Other functions are unaffected. To remove the warning light, simply turn the car off and on again. To enable the app to work again fully, you need to logon to CarWings using a computer. Logon, click the CarWings button, an error is displayed. Log off and on again, click the CarWings button again, an error is displayed but CarWings data is visible. Log off and on third time and everything is back to normal. The app then works normally again. Phew!! Hope this doesn't happen too often. At the moment, once every fortnight. I gather this situation will be very rare, but if you come across it, you will know what to do.
