Guess ur car is nissan primera 2002 -2007 well good luck with d programming but first before buying new brain box do u had a scan? If yes is it an immobilizer issue that is d NAT5 system do through check before replacing ur brain box please it almost cost me all my savings I was buying everything. The system is tricky oh pls be careful had to park mine for 6months when it turns me into mobile ATM. Finally succor came when I have the right rewire do a check and detects it's burnt cables and direct earthing problem within d system, the guy was so loyal and trust worthy he help even return some parts I bought to ladipo nd he re programme the original brain back. Pls it's not mechanic work oh but a sound rewire technician. If u d d rewire that helped me let me know. His fees is not up to d 15k ur guys are charging and I can tell u he will fix it before charging u

It would appear you didn't read through Goldbearer's original response. Because, he's answered your question, with regards to programming.

Does your car have an immobiliser?

Yes it can be up to that because Nissan Immobilizer system (NATS) can be a hard knock to crack and is not direct like most japanese car.The programming process will involve acquiring pin code from another third party source which will used for the programming .
But I i will advice you to take your car to a competent technician to troubleshoot the issue inside out to really conclude that you have a faulty ecu .

he made mention of the pin to be acquired by another third party , and technician says the ECU is faulty . do you know how i can acquire the pin to help reduce cost of expenses

On the dash board , there is a key always flashing in red colour , i already bought a new ecu, according to the scan , the technician said the ecu is faulty . the car starts when cold ,and hardly start when hot, there is a little smoke in the exhaust pipe .i bought new fuel pump, crank shaft sensor etc.

I don't think your technician knows what he is doing, you are not supposed to buy these parts, once I saw fuel pump, crankshaft position sensor and new ECU I quickly knew he is a quack, the simple thing is this, put the original ECU back and start the car, then allow the engine to warm up, then make the car act up again, when it refuses to start, then you check for two things, Spark and fuel. An engine needs three things to start, they are spark, fuel and compression (air), but you check for two because it starts, albeit when cold, so at that time it refused to start check for the missing component, it should either be spark or fuel.

First, no new ECU (brainbox) goes for 25k so yours is used. Second, 15k for programming is way too cheap, that is if it is an actual ECU reprogramming.

Unless he is referring to key registration.

Key flashing suggests a NATS issue. Does the flashing stop when you turn the ignition on? We need the precise code of the scan result.

If your car can start at cold then why concluding u have a ecu issue ?
Re: About Brain Box Reprogamming. by nurey(m): 8:36pm On Jul 12, 2016
If your car starts at cold temperature and starts misbehaving when hot, like loss of power, erratic rev, extreme earthquake vibration. Then look no further than the crank and cam sensor in the engine, start with those first since its a Nissan.

As for the NATS system, if the engine starts with the key blinking, you need to relearn it, since I don't know the Nissan model and year, I don't know whether the relearn process would be same as my Ex-Nissan Almera N16.

The P12 and the N16 have the same system.

ok, i will re scan it and bring the scan code. The key does not stop flashing, it flashes always.

please they have scatter my car. they have brought two different brain box and the car doesnt start. the old ecu only starts the car and the car wont pick up, it when u pedal the throttle nothing happens.
Re: About Brain Box Reprogamming. by klens(m): 8:27am On Jul 23, 2016
My car has stayed a month plus now in the mechanic, now the car starts and the engine is very low, it doents pick up, even when you fire the throttle. they have brouth different brain box non work, the technician i finally met told me they will have to buy ecu with the same number or another one with the bcm box.

Please what do you suggest i do now?
see my ECU code: MEC30-010
MEC30-010 C2 2320
4F

And the code of the last one they bought: MEC30-020
MEC30-020 D2 2227
4G

You are not following laid down rules in this forum and obviously you won't get needed help. Note I am not a mechanic at all, just a Google engineer expert.

Even if they change all the parts in that car, it won't be normal so follow my lay down rules and together we will fix your problem.

1. Nothing is wrong with your former brain box have them fix it back, also your fuel pump and injectors are fine, don't let them touch that.

2. Now that all former things have been fixed, let's go back to square one. Have that car scanned first of all, then let's know the code. Except the scanner doesn't communicate with the ECU, then we know the next step. Scan is important to determine what to do next, with out giving me a reply to my step two, I may turn to an online kazeem.

This is 21st century, if your brain box is bad, the car won't crank not to talk of starting. Brother scan the car first and let's take it from there

I have a sienna 1999 model xle and I have been unable to drive my since two weeks now due to the engine sensor wire got cut and the car refused to start again and the electrician I called discovered the there's no spark on the high tension plugs and went ahead to the brainbox to cut the story short,the brainbox is damaged now,can a free code brainbox with new key start the engine?
Pls experts here I need your advice
Thank you

There is a reason your vehicle came with an immobilizer.

If you care about meeting your vehicle where you parked it, install an exact fit brainbox.

If it does not matter to go, go the freecode way.

Your car, your choice.

My thoughts though.
