Here's the transmission and inverter

is there a controller for the 2019-20 version? also have pics?

VCU pending - transmission still up for sale

it is but only one post makes me warry

My project has taken a different route and I no longer have a need for my Lexus vcu or transmission. The VCU is already built and the code is loaded and set up. I also have the box it goes in and two wire harnesses. One is built by me and has all connectors on it. The other harness is just started b...

Looks like I have a dead inverter - I thought I saw somewhere on here that a guy bought a couple, repaired a part in the middle that would go bad, and then have a good unit again. I can't seem to find that post or what part that is. I'm getting no communication from the VCU and the inverter This co...

Im at NC/VA area but I don't see anyone near this area

That's pretty amazing! I finished my stock harness and tried everything again - Nothing

Anybody have a working inverter they can spare - either to let me test and i'll pay shipping or one to sell?

These are the only grounds I see - they are all connected if thats what you mean by a common ground

this version v3.01

Does anyone know what the next steps should be - I want to verify everything before I get a new inverter. I checked and recheck the wires - and I'm building a new harness from a stock one - just to verify. I just don't seem to be getting anything from the inverter to the VCU Screenshot_20211122-0845...

set everything up and all seemed well - then nothing! I can't seem to get anything on the inverter. I have done everything I can think of. I bought a new wire harness to make a very clean one and i'll try that but I don't think it's the wires. I'll get it eventually but I was hoping to get the trans...

Soooooo - I have have spent many many hours trying to figure out my inverter and think I may have a dead unit :( its very frustrating and annoying. I like 99.999999% sure my wiring is correct as I have gone over it 4 times. While there still might be something I don't see that's wrong, I don't think...

def not me! I have so much work to do and only a hour or two after the fam is asleep to do it, and after a full day of work

You should definitely hear high pitch noise from inverter when you apply High Voltage. I know you checked wiring but you can also cross check against my old and really bad video linked below, perhaps you missed something. Keep in mind it was done with Camry inverter which has slightly different mai...

Is there a way to just test the inverter, to see if it's good or not. I'm literally going crazy as I can't get things to spin. I tested my throttle and i'm getting a 0 to 495 and I set it via the serial and I loaded the program and have check my wiring 3 times . The only thing I do notice, that I d...

ground.JPG That may be my issue as I didn't hook a relay to the B and B2 , as it looks like they where connected together and just connected to positive via the 10amp fuse - so if I'm reading this right now B and B2 connect together and go to 5(87) on a relay - 2(85) and the relay goes positive via...

Ok I just need to confirm a few things as I finished pinning and wiring up everything - check my wires and put 60v to the invertor and got NOTHING! Very frustrating. I checked and double checked - I even ordered a new pedal and a 5k pot just to test things. When 12v is turned on I here a relay click...

For what it's worth, I think it makes more sense to use pins 6 and 9 (FWD and REV) instead or R and D. This way, you can use the momentary "B" position without it dropping into neutral. do you mean you can just use a momentary push button and hit pin 6 or 9 with 12v for a second and it go...

Ok I'm slightly confused here - and maybe I just missed it but I plan on wiring up the connector and using the manual lever so I have a mechanical brake BUT these two diagrams are different in the wire schematic. The connector says pin 1 is drive but the but on the colored diagram 3 is drive? P is 3...

On a separate related note - the two wires coming out of each resolver on the transmission, pins 4 and 8 - is there a way to hook those to a separate device like a Arduino or something and have a screen displaying the temps?

latest build progress - I'm 95% done on the 450H driveline, that might be the next video.

Here's the latest episode I forgot to post here. Wider is always better
