https://myimiev.com/threads/mcu-20a-450vdc-fuse-investigation.4310/ Just found this thread when searching for "N71P49691 450VDC". It was the only search hit on "MEIDEN Shizuki N71P49691 800uF 450VDC 2490031". So yeah, it's a capacitor. Kiev shared this in that thread. And there I was just...

Alright. Update #2. Here is a longer version of the MCU removal process. I'd not seen a comprehensive video online yet for this for the i-miev MCU removal. So here is a general overview of how to remove the cover and all the cables as well as drain the coolant hose. FYI! You DON"T have to...

Status update. I was able to pull out the entire MCU today. Now I understand how it's all connected and put together. Turns out you don't have to take it out to swap just the IGBTs if you don't want to. It's a lot of work having to disconnect everything and drain the coolant. If you just have...

:) Haha. You forgot the /s at the end. lol. But I got it. Okay. Thanks. I'll take the hint. I do need to read more. RTFM FTW!

Charging works! I'll post some pics later. Okay, I'm opening up the MCU cover now. Got the main fuse removed. But this thing is glued tight! Any videos showing this? Can't find much anywhere yet. All the videos online don't show how they got the cover unstuck from the sealant. But it's not...

Okay. Correct readings now with the correct hobdrive profile chosen: Miev -Li-Ion: 88 cell volt BMU page 66 cell temp page 66 Temp Diagram page MCU page EV-ECU page CHARGE page BMU page CMU6 page. So why does page 6 and 12 show only 4 cells vs 8 cells for all the other modules? CMU1...

Seems that car scanner says the OBD-II protocol used to talk to my 2011 JDM miev is ISO 15765-4 CAN. 11 bit ID, 500 kbaud. So are these identifier numbers used for anything? asdf asdf

Oh, so to clean that back motor compartment of dust. You'd posted earlier I can just vacuum it and then use soapy water on it? Safe to get lots of water in there and hose it all out? Or don't over do it with the water? I wouldn't mind getting one good high pressure hose-down in there but don't...

Okay. Good to know. Thanks. I'll definitely be using the multimeter on the incoming battery leads to the MCU before continuing to work in there after pulling the main fuse. Always best to check and be sure. Thank you. Will do.

Thanks. I didn't realize I'd chosen the miev van profile originally. Definite oversight. I've added the following note above to the posts with that 117 cell screenshot and will post more correct screenshots later. I wanted to keep the mistakes posted so others could read and learn in order to...

Thank you. Yes, I think so too. Glad to finally contribute back to you guys for all you've given me so far. I've also donated today. Grateful for you guys. So I created a few how to videos on how to easily get the OBDLink LX bluetooth dongle to connect with the recommended apps on android...

@JoeS This thread is a fantastic resource for new i-miev owners to quickly find the best apps to use. Thank you. However I struggled in knowing how to work with the bluetooth dongles in getting them to talk with the apps above. Two days of struggle and frustration. I thought the dongle didn't...

Thank you for your answer and kind offer Neo5. Very gracious of you. I'm in Japan though. It's probably about the same cost to order a spare MCU PN: 9499A620 and just move the IGBTs over if that's the main culprit. Thank you for confirming it's fairly easy and is a confirmed fix. You should...

It's also showing those high voltages in the 117 Diagram CMU page. Seems to be in CMU6: For CMU6_Voltage05 and CMU6_Voltage06 as well as 7 and 8. If true, wouldn't this be dangerous? Is this four shorted modules? Or likely a misreading by the CMU? Later Edit: My i-miev does NOT have 117...

Alright. I've got more good news. I was able to get hobdrive and canion talking to the car finally. I have to say, these obd2 bluetooth dongles are finicky. You have to be patient with them and basically disconnect them and shut off and turn on the ignition each time to be sure the app will...

Thanks again for your kind reply Gary. Quick question, do you know if MCU part number 9499A170 is compatible with 9499A620? Are they interchangeble to the car? And do you know if the internals are identical between models or slightly different? My car has the A620 version in it from the...

@coulomb Hello sir. Sorry to ping you for the first time out of the blue in a random thread. I'm very impressed by your knowledge and what you share with the community here. Thank you for all you do. Do you happen to know anything further about the MCU units in regards to reprogramming their...

Hi Neo5. I have the exact same issue as you. Car starts and goes into ready just fine. But if I put it in to D or R I get the exclamation mark immediately as the car tries to move a half inch but can't. Then the car will not move at all thereafter. No ability to go forward or backward. Error...

Oh, wow. The VIN number can be only changed one time?

Were you able to figure it out eventually?
