Please, guys I help form Nissan Maxima 200 Model. Honestly the car has been parked for almost 2months now because of one electrician carelessness. i had a kick starter problem that required the replacement of the brush, rather than doing just that he sparked my battery head which lead to the loosing memory (as they said) and since then the security light has refused to go off so the car cannot start. Have tried more than 7-brain boxes to no avail. Meanwhile the box is the card type as the called it. Please, what can i do as i still wish to use the car, because before now i have never had any problems with the ride and loosing the kick was the first loose, nothing has been done on the too. My people i need help

You probably need to reprogram the immobiliser.... Has any of the Kazeem's attempted to program the immobiliser?

Its common with Nissan. If you tamper with the battery with the key inside the ignition forget it u will need to decode abi it is reprogram it. It is 5k naira if u know the programmer at most 10k.

You certainly caused an electrical breach. I presume the car has in tow disallowed communication with a scan tool. Check the ECM relay and other relevant fuses for damage. Restore the original ECM, which is still most likely intact. Feedback.

they have tried programming to no avail

it has finally responded to programming with the 10th brain box but still refused to start.
Now the current flashes on the spark plugs, the current cuts off immediately and the car is not starting.
Now someone is telling me to open up the flywheel for cleaning that i might have some dirt on the face. My pple i tire joor!!!!!!

Post the numbers on your original brain box and those of the last (10th) brain box.

I returned them to the people that brought them but for thr original brain box i'll check it out.
meanwhile, it has been programmed with one brain box, there is current supplies on the plugs now but the nuzzles seem to be too open and pushing in excess petrol to the burning chambers causing it not to start. am suspecting that this brain box is equally bad . please what do i do next guys

Costee:

I doubt If you have ecu issue what you have is electrical issue ,your ecu is offline which is the reason your security flag is permanently on .
Install your old ecu back and get a professional technician and not a rewire o ; someone skilled in reading and interpreting wiring diagram to check this for you .

Thanks man, but the security light now goes off with the ignition as its used to be, i mean with this last brain box but the excess fuel on the burning chamber, the plugs gets soaked

y not go with the advice..... u have issues and u came for advise @ the 6th brain box....... now u r at the 10th and still unwilling to take the advice.

SMH, finally maybe at the 15th ecu the car will start well.

the first one burnt, when open you could see the black burnt stuff like diodes and capacitors within. that was why the replacement started.
please don't get me wrong

oh OK, I didn't see that..... so he fried ur ecu.
u have to get a direct fitment ecu else u will still have issues with a makeshift one.

Honestly bros, that's the problem am having getting the direct fit.
the car came with the so called card type, because it has a kind of smart card inside. so seems not too common. i tire meen

do u still have access to the original ecu? if yes, there is a part no on the sticker of that ecu.... a no.. yes
..

post the numbers as-is, this is y u r here on nairaland.... free consultation innit? post it BRO let's take it from there

Thanks a lot man......i'll do that after next week please because am on duty till 7th of next month so off the house for now. But let see if my people can get it for me right away.

This is the group number you should look out for:3E A56-P39 Z50. The last four digits, 9615 designates the date of production of your car, 1999, June 15. Google the group number as you ultimately might have to buy one online.

Please, could you direct me on how and what exactly to search through Google.

Haaaa, the baba for the Nissan is already here.....

OK na,

or instead of trial and error, he can just give his techie there this info to guide him

All this running around without scanning is ridiculously expensive.

Multi meter and YouTube would have soled this problem in less than an hour

Good morning My Brother, the car was scanned and before the brain replacement started. they have not really touched any other part or the wiring /electrical system. the car is even parked within my compound to be on the safe side....................................

i guess this is it https://www.ebay.com/p/00-Infiniti-i30-Nissan-Maxima-AT-ECM-ECM-ENGINE-Computer-A56-P39-Z50/1429971249

If this is the true position of the car, then do nothing further until you're able to install a good ecm that's an exact match to yours-- and that includes no further experimentation with imprecisely matched ecm.
You may post the VIN or send it to the number in my signature to enable me confirm if there was an upgraded version of your ecm.

If and when you get the ECU and you want trustworthy hands to put you through and get your machine back on the road

Provided you don't mind paying for my coming and going I can help you solve this once and for all in association with Costee whom I have an excellent working relationship

He knows and you should know if you follow my threads that I strive to follow best practice in all affairs

For me it is the best or nothing

The Nissan overlord's input and my physical presence my be just the magic needed to resurrect your Nissan

Just giving you one more option given the confusion of the last few months
