I do not have log but i will log it.

Hi skojon, did you managed to sort this out? I am also facing similar bahaviour at one of the projects. below 4V seem balancing fine, but then it stops. Not sure if it is precicely the 4.0V, but anyway it stops at hig voltages. First i believed it was the ...

Specify which inverter

Yes, it is 110kW inverter.
I tested unplugging this temp sensor plug and it resulted the IGBTDriverBoardTemperature to be FF so think the external sensor is reflected to this byte in message 55a.

Is it possible you have an air lock in the Inverter?


Could be yes. Air locks will definitely be there if I fill normally via radiator. I have found out to fill it better using vacuum filler tool. I think I need to isolate this by doing a special cooling circuit for test. This one is easier than ...

Hi, I have been driving my Leaf conversion for 2+ years and 50k km's without much of trouble. Just recently, I have seen temperature rising in CAN, not in the real world. It is stock 110kW inv + gen3 PDM + EM57. CAN message 0x55a byte1 is going crazy. I have understood it is temperature with 0.5C ...

Luckily I have a second unit at hand and after soldering the connector to it, I plugged in the connector of the first unit to it for test. And yes, it works. Leds illuminate, so the first one was a DoA.

The second unit is working fine and I have managed to get Digital outputs (logic level, lout ...

Here it comes. If only red (+12V) and black (gnd) at my fingers are connected, shouldn’t the unit wake up and led glow?

The problem is, I tried to wrap my brain around these for about half an hour now and haven't yet figured it out...


Glad others are struggling with register settings, so not only me. I keep trying.

My another strugle with the board is, I am able to get the program running on it and it seems to ...

Hi, I have been testing ipdm56 now on the bench. Looks good. However, I see CAN libraries does not support speed 83.3kbps. I think some other variations of the mcp_can, such as Longan labs version, support this rare speed, but it is with 16MHz clock. I think I saw in the schema a 8MHz oscillators ...

Hi, tried to search this from forum, but couldn't find.
Has anyone tested the minimum battery voltage the onboard charger at PDM supports? I am playing with gen2 and gen3 PDM's with 60S config. The DCDC works fine and so does the inverter and engine. But it won't charge. Voltage in my pack is ...

I have seen current draw peaking 300A, so way over 110kW momentarily.

Will I fry the inverter, if I use a PSA 50kWh pack, which has 108s config, instead of the 96s?



I have 108S pack in my setup and has been fine for a year and 20.000+ km’s. It is full 9 module ID.3 pack. Running stock Leaf 110kW inverter with Resolve-EV and Simpbms. And max voltage is 450 ...

Hi, What is the easiest method to verify if 4-way CMU CAN ID's overlap? I have some CMU's from different packs that I would like to use in a same canbus. Is there an easy way to determine how each CMU is identified. I have learned these id's cannot be changed, but would like to understand if I need ...

Yes, this led me to the right direction. I started to measure different tranceivers I have at hand and as I was not adding any terminators myself, I finally found out, that all my Teensy tranceivers included terminators. While unsoldering the terminator out, I managed to have it working.

So case ...

Teensy flexcan library should support 83333 speed. And this can be verified with Pcan-view. Sample code I am using with Teensy 4 is as following:

#include <FlexCAN_T4.h>

FlexCAN_T4<CAN1, RX_SIZE_256, TX_SIZE_16> can1;
uint8_t i;

void setup(void) {

pinMode(2, OUTPUT); digitalWrite(2, LOW ...

Hi, thanks for the suggestions. I was also (still am) considering if the baudrate was wrong. Internet is suggesting it may be 125k. Unfortunately, I was not able to have Pcan-view (version 5.0.2.838 64bit) recognize the traffic with any other speed than 83.3k. And Linux can utils (candump) also ...

Hi, I am loosing my faith with the topic of hooking into Jeep Patriot interior canbus with 83.3kbs. The bus seem to be very picky and I have tested many different boards without luck to it.

My objective is to have 3 channel bridge device with two at 83.3k and one 500k speed. My intention is to ...

Great. Works like a charm. Good job Tom!

Thanks for the encouragement. Then I just let it run. And I do agree, that is great and probably the only real plug and play part in conversion. It just works.

I have installed zafira ps pump and it is indeed a noisy one but doing its job.
Has anyone found any K-bus decoding or other manner to control its speed. I presume, running it in fail safe mode long, will kill the unit.
All tips welcomed. Thanks.

How is the heat intensity controlled and where is it done?


Trying to mimic the work shown at link (https://ev-olution.yolasite.com/nissan-leaf-ptc-heater-aftermarket-lin-controller.php). I only have 170V dc available at home now and feels the heater is not working with that. I keep trying ...

Hi, has anyone been able to figure out the polarity of the HV connector of the Leaf ptc heater 27143-3NF1A?
Even it is resistive load, I guess, the polarity matters.

Many thanks!

did you manage to locking actuator wired properly?

Yes, after first some wrong ones, the correct diagram was found.

The wiring diagram is like this: I may try to update the wiki, if I learn how to do it.

Hi. I have tried to read all the 670 posts in this thread, but could not find the i3 CCS port locking actuator pinout. I see the schematic in the wiki and that is clear. Obviously feedback/gnd may be measured, but the polarity of the locking motor is unclear. If someone has this sorted already, this ...

Wow. Got it spinning with the single frame only. Thanks for sharing. Could you pls explain this 0 and 1 bit reflection to ac power, how to use? Many thanks!

Thanks Tom. Good work.
