I have a 2013 leaf inveter,and pdm running using a zombie vcu running v2.00 firmware,the motor runs well on my car.However I have a problem with the pdm in which the DC-DC kicks in 14.0volts after powering it on after 14 or so seconds even without the zombie powered.im trying to get the AC charging working as per damiens video setiup but not able to get the it running.using savvy CAN the following can IDS are sent from the PDM after powering up (0*390 ,0*393 , 0*679) nothing happens. in USING the original leaf 96 series cells with an ORION BMS2

Do you have the prox and pilot signals wired up and the HV interlock wires off the pdm tied together?

My charger is not currently running also

Which are the HV interlock wires off the PDM?

pin 12 and 15 according to this


Pin 10, Plug in signal, LightGreen
Pin 11, EV System CAN-L, DarkGreen
Pin 12, HV detecting circuit Interlock In, Orange
Pin 15, HV detecting signal Interlock Out, Pink
Pin16 Power On (IGN) , Violet
Pin 18, Battery Power Supply, Red
Pin 27, EV System CAN-H, Blue
Pin 29, EVSE Connection Signal, White
Pin30, EVSE communication PWM, Brown



*HV interlock is not needed according to damien

Any updates?

I've got similar problem with my 2017 Leaf full stack (including LBC)
What I have is contactors closing and motor runs, EVSE clicks like it would charge, but no current moving.

Since I have the LBC screaming in CAN1, I've muted the LBC spoofing messages from Inverter and PDM modules of the code.
I activate the Inverter also on charge, so I can get inverter voltage for precharge just as Leaf originally does.

Some tips pointing towards possible issues that I'm missing.
I do have the PP and CP correctly wired. I used a multimeter with freq counter/duty% to see if I have the 1kHz on CP. Yes I do, it showed maybe 17% duty.

I've been banging my head on this for quite some time now

Last night I found Kelju's post and was thinkin if I should try this also

I managed to make a fork of the Zombie main branch so I can share my hackery. I wouldn't call my copy pasting coding, but if I get this working, maybe someone else can also benefit from this Something messed up on my git push-pull-fetch game, so I lost some of my changes and I started over. So at the moment I haven't tested if this works or not.

You also have a leaf pack on the same bus right? Then heavy code modification is required to ensure no ID conflicts ect as the Zombie pretends to be the Leaf BMS.

I don't see it really as heavy, just read the shutn type from parameters (added Leaf BMS as shunt type) then wrapped the LBC spoof messages for both inverter and PDM
LBC messages to be wrapped
0x1DB LBC (10ms)
0x1DC LBC (10ms)
0x55B LBC (100ms)
0x59E LBC (500ms)
0x5BC LBC (100ms)

Other option would to put the Leaf BMS on CAN2 and that I'll do if I won't get this working

There are people who have the setup working successfully with a full leaf stack and stock Zombie firmware. You could try making it work without talking to the BMS to start. Just to prove it works before making your changes and adding the BMS back on the CAN.

Hi J0hannes
Any update on this, I have the stack, but am only using the gen2 motor and invertor so far on my build, I would like to use the PDM too, I thought people were having problems getting the PDM to work ( the charging side ).
There are so many pages to go through
I don't have the Zombie, I will get one If it works the stack with it.

I'm still struggling to find out the WHY in my setup not working. (Meaning EVSE clicking charge status, PDM actually moving charge power to battery)
I've also been trying to browse the projects to see if anyone would have confirmed a working charging setup and which software version they're using.
In the Chademo & Leaf PDM thread there's also discussion on this.

I've had Zombie software V 2.04 & 2.05 as a base for my fiddling. Latest with 2.14 iteration.

I do realize that I may have too many things going on/in the change to really see what influences what.

• But as I'm typing this I see that maybe I should go all the way back to version 2.0 since that's atleast a version I can find confirmation of working.

• Second, I sort of forgot to go through with the setup testing so that I'd have the Leaf LBC in CAN2 so it wouldn't interfere with the messages, that may be easier said than done

• My EVSE is a YAZAKI charger from an Mitsubishi Outlander PHEV. Did realize that I've not actually confirmed that it works as it should as I bought it second hand.

You try this yet?

Not yet, but I have added that on the to-do list. Have to get a grip on this and be more systematic. Now I've done fiddling here and there (maybe gotten something out of it) but usually had better result If I've managed to keep a step-by-step approach...

Hi. is is possible to power on full Leaf 2015 car with ZombieVerter? i would like to test all on actual Leaf donor car before taking components of it.
As I understand the ZombieVerter could use Leaf BMS messages instead of ISA shunt?
Waiting for VCU to come to start testing

Well, now I got the AC charging working.

I don't see why you couldn't do it. Depending on to what extent you want to have the Zombieverter controlled setup working in the Leaf, you would have to still figure out how to control the parking actuator, IPDM and maybe few other components. Also you need to modify the wiring harness and for example modify the contactor control as Leaf has positive voltage control (high side outputs), Zombie does negative voltage control (low side outputs).

There's probably going to be lots to figure out by yourself and combining information that is scattered all around the interwebs, so if you do this, please make a project topic and document your process, so the knowledge is spread

What has helped me out a metric ton, has been the Leaf Service manuals.
For your scope, at least VC (EV charging system), EVC (EV vontrol system), EVB (EV battery system) and TMS (traction motor system) manuals are the ones you should start with

Oh and if you are not code -oriented, LeafSpy pro is a cheap investment as you can read and reset the DTCs of the vehicle modules.

Hi. Leaf service manuals, wirings are beeing analised. Leafspy pro is in the pocket for last 2 years received Zombie, will try to destroy still drivable Leaf. Just passed inspection and is road legal for next 2 years. Should be good test kit before installing it in receipent car
