HOW-TO: 2018 Leaf ZE1 OEM headunit replacement (7" -> 8")

[explorer232]

I have some news. In my case on the Unit ID Information screen there is no SIM ID filled. So there is some difference in 4G TCU first gen vs second GEN in communication. Could someone else confirm that there is no SIM ID filled ?

 

[Hybrid]

Tried two units now, both 25915-5SN0C on a JDM 2018 LEAF with 360 AVM Cameras and Pro-Pilot, and unfortunately no luck getting the units to fully function.

• Unit 1 - 08/2019 build (unk trim) with firmware 283C32311E
• Unit 2 - 04/2019 build Tekna trim with firmware 283C39344R

Confirmed wiring correct and Bosch AV unit is getting all signals such as Ignition, PKB, ACC, Reverse etc

Current Issues

• 360 degree cameras - No response when pressing the camera button or going into reverse.
• AV clock won't sync with the dash clock
• HVAC very slow displaying onscreen changes
• AV unit does not auto dim with headlights

Following DTC errors on both

• EV/HEV Can Error EVC-279 (EV/HEV is the cars ECU)
• EV/HEV Can Comm Circuit
• AVM Can Comm Circuit (possibly incompatible with the JDM AVM module?)
• Meter Can Comm Circuit (Meter = dash cluster)

Interestingly on the QY Clarion unit, which is actually a UK unit works flawlessly with no codes. I have to set the Camera's as FAP not AVM for them to work.

Unsure what FAP means, maybe related to Pro-Pilot Pilot in which case because you can't set it in the Bosch unit is likely the camera issue. If I set the Clarion unit to AVM they don't function at all.

I think at this point both firmware's are not compatible with the JDM LEAF control modules and dash cluster, and likely the camera setting not being set to FAP.

Hey, if anyone inside the EU is in interested in this mod, I have my 8" headunit + adapter cable (including the Zelemar unit!) for sale. Sold my Leaf last year.
Fully working (just note the caveats in first post) and ready to go for a Tekna level Leaf (360 cameras, Bose etc.) with no extra configuration needed.

Model number: 25915-5SN0C

Shoot me a DM. Asking for 250€ including postage.

Hi all

late to the party here but just wondering if someone can do me a favour. Ive tried wiring up the harness and I think my skills leave a lot to be desired but I wonder if anyone is willing to test my 8" unit that I bought to check its working. It was from ebay and although it said working I cant verify it.

Obviously I would be willing to drive to you (south east would be preferable if possible, Im in Hertfordshire).

Also if anyone is better after subsequently at wiring a harness for me I would be willing to pay! I need to get this working so I can sell my leaf and get a half decent amount for it!

Running a 18 plate tekna.

Cheers

Phill

Hi after switching from 7" to 8" unit i have these faults on diagnostic menu , can someone help nie with that ? The antenna is most important

 

[Deleted member 38436]

Hi Mike

Did you do the wiring yourself or get a harness made elsewhere?

Hi Mike

i did it, however the antena is separate plug with 2 wires and i needed to take out pins from plug because it wasn't fit to 8" headunit
the unit comes from nonBOSE car and is set to 360camera
my car has BOSE and 360 camera with self parking
so for now audio is loud as hell and no camera view at all
i need to visit dealer but i doubt that they can help me with antenna

Wasnt there a thing earlier in the thread that says you need to shave down the antenna plug and it will fit?

 

[miikew]

well, i wanted to leave plugs untouched , so i take out pins, cover it with shrink tube and connect to new headunit

Сейчас попробовал два устройства, оба 25915-5SN0C , на JDM 2018 LEAF с камерами 360 AVM и Pro-Pilot, но, к сожалению, не удалось добиться полной работоспособности устройств.

• Unit 1 - сборка 08/2019 (unk Trim) с прошивкой 283C32311E
• Unit 2 - сборка Tekna 04/2019 с прошивкой 283C39344R

Подтверждено правильность проводки, и AV-блок Bosch получает все сигналы, такие как зажигание, PKB, ACC, задний ход и т. д.

Актуальные вопросы

• Камеры 360 градусов — нет реакции при нажатии кнопки камеры или включении заднего хода.
• AV-часы не синхронизируются с часами приборной панели
• HVAC очень медленно отображает изменения на экране
• AV-блок не затемняет автоматически фары

Следующие ошибки DTC на обоих

• EV/HEV может вызвать ошибку EVC-279 (EV/HEV — это ЭБУ автомобиля)
• Схема связи EV/HEV Can Comm
• Схема связи AVM Can (возможно, несовместима с модулем JDM AVM?)
• Цепь связи Meter Can (Счетчик = приборная панель)

Интересно, что устройство QY Clarion, которое на самом деле является британским устройством, работает безупречно, без каких-либо кодов. Чтобы они работали, мне нужно настроить камеру как FAP, а не AVM.

Непонятно, что означает FAP, возможно, это связано с Pro-Pilot Pilot, и в этом случае, поскольку вы не можете настроить его в устройстве Bosch, скорее всего, проблема с камерой. Если я установлю для Clarion режим AVM, они вообще не будут работать.

Я думаю, что на данный момент обе прошивки несовместимы с модулями управления JDM LEAF и приборной панелью, и, вероятно, для настройки камеры не установлено значение FAP.

Здравствуйте. У меня такая же проблема, вдруг, перестали работать все камеры, и не реагирует на кнопку. Что делать?

Did you manage to get the cameras working?

 

[miikew]

anyone knows, is there a difference in wiring between 360camera and 360camera+self parking ? i took 8" headunit from car that had only 360camera to car that have self parking and i have no picture from any camera

I got the same issue. No picture from cameras and I got the self parking option in my car. Hopefully the dealer could code it somehow

 

[miikew]

well, it can be that wiring is wrong
here is wiring for 2019, but it loks like it is only for 7" , no option for 8" headunit , anyone have wirings for 8" ?

I would take a look at the Nissan service manuals at this point.

They're available at https://www.nissan-techinfo.com/ which is where I got the details used to make the pin diagrams in the first post. It costs $20 for 24 hours but it's well worth it.

Now that I think about it, I suppose the control units for cars with auto park and without are different.

If AVM stands for Around View Monitor (cars without autopark), could FAP stand for F[...] Auto Park in the Nissan manuals (and software?)
Man if you guys find different pinouts in the service manuals for FAP cars that'll change the game and explain so many camera incompatibilities lately.

access to https://www.nissan-techinfo.com/ is only for authorized services , how can i get it ?

Hi all,

I am working on version for leaf ze0. I found probably only one possible solution how fit BIG ZE1 headunit to ze0 trim. I removed plastic part about the ze1 display + some easy ze0 trim modifications. Last step is cut ze0 trim to two pieces to access headunit screws. If all will be working fine I will modify ze1 headunit plastic part to give modification proffesional look (hide pcb from display) . Now I am working on headunit cable.

Have you had any luck with this? It looked like the steering wheel switches might not work, but I was wondering if the head unit functions otherwise normally.

I have 7" HU, And I decide to buy 8" HU.
I have ordered one from Partan.eu and it is 259155SN0C since it is most compatible version.

First I will try coding HU, because I have friend who works at universal garage.
He has Launch X431 tablet, so I did try connect and test. (no changes but viewing if I can see programming)
It seems I can configure settings. I don't know about coding to vin or so.
But I can safe configuration or so.

Oh I cannot enter service mode by pressing 3x map, 2x power, 1x map. (at map mode)

Multi AV info.


Ignore fault code it has problem with DAB connector or so, tapping on Multi AV you will enter program list.


Configuration code works, other does not works (I think reprogramming is vin coding, or need new HU installed not sure yet)


I hope this will read and write vin coding


This is my configuration of Multi AV, and can save settings to load configuration to other module.


You can write saved data or do manual configure. (not tested writing data, will do after I got new Headunit)

i was at dealer and asks for coding my headunit (i need to add propilotpark and bose to my HU) and they say that this is not possible with NISSAN CONSULT

 

[Kirito]

HU is unlocked after just re-register 2 keys I have. No can filter installed.
Just any workshop who can register keys will do, no need to go dealer.






Here it keeps on LVDS instead AVM or so.
Antenna is fixed.


After configure settings.


I can configure trim settings. But for some reason AVM with pro pilot parking does not work. Screen stays black while in reverse.




It show correct vin info


Maybe I am missing something about avm with pro pilot parking.

IC works, but will let you know if still works after few days.
