2013 Nissan Leaf - won't start

Mon Jul 01, 2019 6:17 pm

TLDR: Car won't go into run mode. Looking for common reasons for why that might be, or better yet, possible solutions.

Hello everyone, so it has been a while since I've needed to post. About 2 weeks ago my Leaf wouldn't go into run mode, as if it wouldn't recognize that the brake was depressed. I had a quick phone call and the kids in the car, and by the time I came back I had a T/M system malfunction. 12v battery drained.

Replaced with a new one. Made sure it was fully charged, left the car without 12v battery for a while, applied the brake pedal just to make sure no charge in the system, still won't go into run mode. Indicates I need to push the brake and hit start. I hear a click behind the dash, but then wont go into run mode.

Took it to a dealership, and they quoted me 4 hours of diagnosis time at $145/hr (canadian).

I've been trying to get my business going, and haven't had a paycheque in about 2 years, so I'm hoping we can try and solve this together, as I can't afford $600 to not potentially fix anything.

I've searched the forums, but most of the solutions that I have come across just indicate changing the 12v battery, which I already did. I tried hooking up my normal OBD2 scanner, but it just gave me an error. I had bought LeafSpy a while ago, but I can't find my bluetooth dongle. When I get the car back I'll check it asap.

You mean you left the new battery out of the car for a while after removing the old one? You may have error codes that have to be cleared before the car will start. LeafSpy Pro will do that, so your #1 step at this point is to get LeafSpy Pro connected to the car. Has the car ever refused to start, or to go into Ready Mode, before this?

I had first tried just taking out the old one, recharging it, and putting it back in. Which didn't work. After recharging it I took it out and immediately put in the new one. Didn't work. Then I took the new one out, left it out for a while, put it back in, didn't work.

Has always gone into ready mode before this. Everything seemed to be a normal day up until that point.

After reading some threads it started to make me get paranoid that maybe I also hit the start button twice really quickly by accident, but I don't think I did... It's that "did I leave the garage door open" kind of feeling.

Have u checked if the brake lights work correctly? A cheap obd bluetooth and the leaf spy will help you findout what may be the problem.

As I wrote: at this point you really need LeafSpy Pro.

So, update: yes brake lights would turn on if I hit the brakes. I felt under the pedal and it seemed as though both switches were working, but that wouldn’t tell me if one isn’t working on the inside.

So once upon a time I had an obd2 reader and had it working with an iPhone. But I can’t find that reader, so I borrowed a friend’s Bluetooth obd2 reader and turns out they don’t like iPhones. So bought another obd2 Bluetooth reader and fetched my android tablet from work.

This time instead of wasting time going across the city to the dealership, I tried it on my other leaf. Turns out leaf spy pro doesn’t like either of the obd2 adapters as they are version 2.1 and it wants version 1.5?!?

So I’m going to borrow another leaf owners obd2 adapter that knows it works, and will try again tomorrow.

Ok so did a little digging. Turns out my new battery was drained over the past week at the dealership so might have to come back again with a fresh battery, but was able to use their battery box to get a bunch of codes from the car, and cleared a number of them. These are the ones that seem to keep coming back:

B142A 1609 air bag
B00A0 0008 air bag
C1A62 0109 brake control mod power supply br-53
C1A6E 0109 brake ev/hev system br-146
C1A70 0108 brake brake control system be-160
U100a 8708 charger
P31E1 000B ev/hev hv system interlock error evc-305
P0A8D 000A motor control 14v power supply evc-132/tms-63
P189d 000a shift
U1a05 0008 tcu usb comm av-199

Ugh.

Those could all be from low 12 volt system voltage. You didn't try recharging the 12 volt battery in the car, or checking its voltage there?

EDIT: from what you wrote it appeared that you did try that, but if the battery you charged was dead, that could have failed to solve the problem. Charge the NEW battery, in the car, clear the codes again, and try to start it.

Had the car towed back to my place, charged the new battery in the car overnight. Accessed via leafspy and had these codes that didn’t want to clear:

C118C 0109 ABS EV/HEV System BRC-126
C1A6E 0109 Brake EV/HEV System BR-146
C1A70 0109 BRAKE Brake control system BR-160
P31E1 000B EV/HEV HV System Interlock Error EVC-305

My memory isn't great anymore, but those look to me like common codes associated with 12 volt battery failure. They could, of course, also be real. They MAY also be associated with a failed brake pedal interlock, although I thought that the Leaf, like most EVs, uses the brake light switch to sense brake pedal activation to allow a start, and you reported that the pedal switch seems to be working...

EDIT: yes on both of the above. Common 12 volt failure codes, and also possible actual ABS or charging system failure. Essentially, the C- codes register whenever the 12 volt system loses power, so it's the last one you should focus on. A failed pre-charge resistor may (or may not) be the culprit.
