Re: 2018-2019 Leaf 2.0 "Service EV System. Unable to restart after power off"

Fri Oct 04, 2019 11:08 am

I have a 2018 Leaf, purchased on 8/25/2018. I drive a lot. As of 9/11/2019, i drove about 24k miles. On 9/11/2019, i got the "Service EV System. Unable to restart after power off" error message, Nissan Roadside assistance towed it to the dealership. It is now more than 3 weeks in the shop. They said it is the Power Delivery Module and the wires/fuses of it. However, they need the part to ship from Japan. It won't be here until Oct 20.... Who knows how long it will take to repair or if they will find more problems... I really need to get on the HOV lanes (free for alternative fuel vehicle, but the loaner doesn't have the alternative fuel tag). Is there anything i can do??

Thanks to henrydehoja I was able to identify operator error.
We charged 2019 Leaf SL PLUS for 3 hours last night on timer, however I forget and left my fob in the cup holder.
The car is my wife's that she drives most of the time. In the morning, I removed my fob from the car and placed back in house.
Later, when she went to drive the car, "Service EV System No Power" error.
Thanks to this post from Oct. 4, 2018 by henrydehoja I was able to follow his procedure, holding my wife's fob in the car and leaving the other fob in the house. Avoided a tow to dealer! Avoided down time without car!
Thank you henrydehoja!

I have not seen that on my 2018 Leaf. However, it sounds like it may be an issue with the vehicle immobilizer system. Below is what I see in the manual on this system:

=================================
NISSAN VEHICLE IMMOBILIZER SYSTEM

The NISSAN Vehicle Immobilizer System will not allow the power switch to be placed in the READY to drive position without the
use of the registered key.

If the power switch fails to place the vehicle into the READY to drive position using the registered key, it may be due to interference
caused by another registered key, an automated toll road device or automated payment device on the key ring. Restart the
EV system using the following procedure:

1. Leave the power switch in the ON position for approximately 5 seconds.
2. Place the power switch in the OFF position and wait approximately 10 seconds.
3. Repeat steps 1 and 2 again.
4. Place the power switch in the READY to drive position while holding the device (which may have caused the interference) separate from the registered key.

If this procedure allows the power switch to be placed in the READY to drive mode, NISSAN recommends placing the registered key on a separate key ring to avoid interference from other devices.

OK, so we actually had a bad cell that shorted the 12volt battery.
replaced under warranty today. Car works fine.

The intermittent warning message "Service EV System, no power" lists several different possible causes in the owners manual.
None of them were that the 12 volt battery might be bad.

We followed the procedure below, and then the car worked.
We replaced the batteries in the FOBs and then the car worked.
The last time, we were in a parking lot, and the warning message appeared.
I went back in the building to use the bathroom after calling AAA for a tow to the dealer.
When I came out and tried to put the car in neutral for the tow truck -- the car worked!
I cancelled the tow and drove straight to the deal.....about 0.5miles.
They replaced the battery at a value of about $400-$500.

Concerned about 2019 Leaf. Love the car, but got the ev warning it would not restart after power off. Had the car for about one year drove 25 000 km. Worried will have problem again outside of the 3 year 60 000 km standard warranty. Had no problem with our 2015 Leaf. It took a month to get car back from dealership.

2019 SL 2400 miles


I just got this code today. Jumped in this morning and drove about a block and code came on turned around parked it in the driveway and not able to move car.
Tried above restart sequence but no luck. Called the dealer but being a Sunday no help. At least I have a little info now after reading all this for when I talk with them in the morning.

Fingers crossed

If you have LeafSpy, try puling error codes. Saves on the hassle of explaining to dealer what's wrong

As of 4-10-20 our 2018 SL with 18,000 miles at 22 months has done the same. No help yet from Nissan USA after a week. Not much help from two local dealerships, lack of service techs due to the C-19 virus. The third distant Nissan dealership may help. I have been one of the biggest advocates of EVs and the Leaf. But if NIssan fails me regarding this issue, well you know. I will update when I finally receive support. Even explaining to Nissan that my wife who needs this vehicle for her transportation to UCSF Children's Hospital, where she has been on the "front line", has made little difference with Nissan to date. Sure enough, build date ---MARCH 2018!

Update: Same fault codes,
P31E7
POAA6
POA8F

Update #2;
Received our Leaf back after exactly 3 weeks at the dealer. Reported that it is a bad cell in the front. It took some time just to get it to the dealer due to slow communication from them. Bought the leafspy app and LeLink 2, and was able to read the codes, then clear them after a screen shot. That way I was able to drive the Leaf to the Dealer. Insisted on a loaner vehicle, which was provided. On the way to the dealer the warning came up again, so the service was able to view the trouble codes also! Service informed me that one of the 192 cells shorted out. They replaced one of the 24 modules, each module contains 8 cells. After a week driving, so far so good. The module that was replaced showed the cells just slightly higher voltage before the replacement. After replacement same module showed slightly lower voltage. Both times read when SOC was at 90%.

Welp, this just happened to me. Now I'm stuck. Car won't charge, either (I had hoped that might reset it). 2018 SL, leased. LeafSpy doesn't report any errors, not sure how to get it to show fault codes.
