Re: i3 controller hacking from diyelectriccar.com
Glad to see someone making progress on this, I hope to get back to it March or April time.

Re: 2015 i3 with REX stuck in Park gear - 222C02 error
Hi, I'm not sure how much I'll be able to help with the EME as electronics is not my specialty however if you can gain access to the parking lock it can be removed OR you can activate the motor by supplying 12v to the outer two pins on the plug. I'm quite happy to send over my old EME board for you ...

Here it is
I found this quite easy, and I am rubbish at this stuff, I can recommend using the i3 some for your pre charge circuit

BMW i3 SME
Hi all
I've got a video going up on YouTube showing how I used the SME or safety box from the i3 for my precharge circuit.
Probably the easiest thing I've done so far, stripped out some wires and boards, put in a timer delay and Bobs your uncle

Re: i3 controller hacking from diyelectriccar.com
Has anyone made any more progress with this? I am now stripping all the unnecessary stuff out of the safety box so I can put that in line with the batteries. I am also uploading another video with the inverter casing work, should be up by the end of the day if anyone is interested. I have put a plat...

Re: i3 controller hacking from diyelectriccar.com
Problem solved then :) You didn't do damage, all that happens is current flowing right through the anti-parallel diodes. They are made for that. That is also a way to determine polarity: put multimeter to diode mode and measure into the poles. If you see a stable 0.5-1.4V then polarity is reversed!...

Re: i3 controller hacking from diyelectriccar.com
So I have checked the capacitor out of the inverter and it is charging and holding, I have checked the safety bulb circuit, checked the polarity etc.
Now I get no light on the bulb at all, even at 60v.

Re: i3 controller hacking from diyelectriccar.com
I've gone back to Johannes' initial inverter video and it looks like I DID have the pos and neg the wrong way round
Let's hope I haven't damaged anything

Thanks!SciroccoEV wrote: βFri Sep 09, 2022 10:16 am Don't look at the capcitor, it's a non polarised type.
Look at the IGBT module!
How can I tell on the IGBT? Again, no markings at all?
If I do a resistance test between the IGBT and the three phase output which would give a small resistance change? Positive or negative?

Re: i3 controller hacking from diyelectriccar.com
I've put a small voltage on the capacitor (less than 10v) and it is holding charge and I have checked with the multimeter and get the correct readings for the large upper tab being the positive. Is this what everyone else has?

Re: i3 controller hacking from diyelectriccar.com
Ok, so there's no markings, I've possibly got confused, can anyone confirm which is positive and which is negative on the capacitor please?

Re: i3 controller hacking from diyelectriccar.com
Would that cause the symptoms I've got?
I take you mean the HV side?
I might do a little video and see if I can make it private for you guys

Re: i3 controller hacking from diyelectriccar.com
Ok, I've been trying to follow Damien and Johannes' Leaf inverter video to ensure all is safe when putting HV to the inverter. I have a bulb in line with the HV wiring and have slowly been increasing the voltage up to 60v. The bulb has a dull glow but does not go out, at the capacitor I have 0.8v. I...

Re: i3 controller hacking from diyelectriccar.com
If anyone knows the pinout of the parking actuator that would be amazing. The motor actuator is 12V to the outer two pins of the plug. Apply 12V in one direction to lock, reverse the polarity on the pins to unlock. You should only need ~5A of current to actuate, and you will head the gears moving i...

I've been doing some reading and I think these numbers on the motor cover could be to do with the position sensors.

My motor seems to be stuck in Park, Damien says it should turn by hand but it's not happening.
Do I have to take the transmission off?
