Nissan Micra owners (2002 onwards) - had problem with ignition or ECU ? (Electronic Control Unit)?

Question

My Micra is only 3 years old, yet suddenly one morning 2 weeks ago it wouldn't start. It started later in the day. Then one morning the intelligent key didn't work, I couldn't get in the car. I got in using manual key but again car didn't start. Just a click, no turn over. Again it was Ok later in day. Next day, the same. Local garage couldn't fix it. I took it to main dealer. They fixed it. Something to do with the communication between electronics and immobiliser? Cost £90. Two days later, same problem. Garage said whole new ECU now needed, by doing previous repair they were trying to keep cost down by only replacing small part but whole ECU needed replacing. Cost £370. Another mechanic then told me there was a recall on some Micras - a faulty ignition. My Micra is 1.2 SE, April 2003.

Answer 1

If there was a recall on the ECU, the dealership should have the notice on it. Take it to a dealership and have them check it for you.
If there is a recall, it shouldn't cost you anything.

Answer 2

Nissan Micra Ignition Switch

Answer 3

For a few years my Micra (2003) would not start in hot weather or when hot inside, until it cooled down. The problem when on and got worst. The original ignition switch was replaced by Nissan during recall and they wanted to charge this time to look at it. I left the staring cover off and notices that when the car does not start and I press the ignition switch from underneath and turn the key it works. So today I have tied two cable ties across the switch and metal key barrel (diagonally on one side). It seem to have worked and I let use see if the hot weather loosens the grip over time. Hope this helps people who have simiarl problem.

Answer 4

There is a recall on ignition switches on k12 micras and more than likely the garage will have plugged your car into consult 2 and it would have shown a fault code and then they have a set procedure they would have followed(matrix) The dealer would have been better to have disconnected battery for at least 10 mins and the re-booted system and then used consult again ensuring the NATS card was used and navigated to the BCM, right handle and started the test and it points to the control unit which is not receiving start signal. Most of the time its the earth connections which are bad for corroding infact when they built these horror cars they did not use the proper connectors and some of the earth points are not earthed ie not making a metal connection. Battery, gearbox, engine bay bulkhead, rear of engine, alternator area and under dash have earth connections which are clearly not sound.
Hope this helps.

Answer 6

I have an 04 Micra which has not given any problem until now. The KEY light which usually comes on GREEN when I press the brake and try to start the engine is coming on RED and I cannot turn the key.
I had to start it with the emergency key. I took it to the local car Locksmith who immediately said "there is a recall on these for this fault " I contacted the Local Nissan dealer who checked the chassis number and said there were actually TWO recalls on my vehicle (1) Steering wheel torque and (2) IPDM Relay. But I cant get it done for nearly a month.
My question is will either of these fix my starting problem ???

Answer 7

Would just like to add, I have a Nissan almeera which is about 4 years old. One morning the thing wouldn't start either. This problem remained for months. To be honest I think the NATS system is flawed. I realised what I was doing wrong was. I was starting up the engine to quickly and switching off the engine too quickly. So now whenever I start up I put the ignition in to electronics for about 10sec and then turn the engine on, then when I switch off I put the Ignition in to electronics for about 10secs and then turn the engine fully off. Since Ive been doing this Ive not had a problem. I think the designers incorporate things like this in to their designs so the dealers can make a bit more money out of the repairs. Sorry you've had your problems.

Answer 8

All new shape micras have been called in to have the ignition switch replaced, just had mine done even though it was not giving any problems, the work was free of charge. Take the car to any nissan agent.

Answer 9

There was a recall. I ve got 03 Micra and took it in for an ignition check in August. I had a new ignition fitted. They didn't tell me if it was faulty though.

That would be your heater core leaking. It would be best to take it to a competent mechanic to have it fixed, shouldn't be more than a 3-4 hour job to replace, unless other problems arise. feel the carpeting under the dash board it may or may not be wet from coolant leaking out of the heater box.
