Nissan Micra 2003 - No crank; NOT STARTER MOTOR

[Ragin]

Hi, my Micra will refuse to start, there is NATS security light popping up and staying constant, but I know it should be working. There is an Electrical buzz sound when turning the key to run. I have replaced the starter motor, no luck. However, when shorting the starter motor when bridging the terminals, it fires right up



Video of sound:


I'm running out of ideas, If you know the issue or similar has happened, please do reply

Where you located, any where close to Birmingham I might be able to help or rule out items.

 

[Ragin]

Sorry friend, im in london.

Ok, this could be a unit replacement that was not done correctly, have you had either the eps, cluster or BCM changed and then recently had a flat better or removed the battery.
I have seen this exact condition due to the security on one of these items, usually the eps as this is the most common change.

 

[Ragin]

I dont think it would the the EPS, no power steering light. What are the common issues with the BCM?

 

[Ragin]

I got the car as a non-runner like this, so I wouldn't have known. But the battery has gone flat. Im going to replace it in a few days and diagnose the immobiliser relay and the starter relay.

I will say 85% eps, seen this many times. The eps has been changed and the NATs has now kicked in, but if your confident it’s not eps let me know how you get on.

 

[Ragin]

If the eps is faulty, then there would be no power steering right?

 

[huttojb]

If it was faulty yes, but if the eps has been replaced by a 2nd hand unit system or some dodgy reman unit, then the eps will NOT be faulty but have the wrong security code. When the battery has gone flat and the NATs kicks in, the car won’t start. But this is only my opinion, and I’m sure you know more about the MIcra then me, let me know how you get on.

 

[Ragin]

Thanks. Ill do a bit of research about the EPS fault until my new battery arrives. Thanks alot

 

[Ragin]

So, if it was the EPS, would I have to replace the whole EPS control unit or just replacing the battery would be good?

 

[Ragin]

I have had a look around, and found this fuse on the web. I saw some charred fuses down there so I think this fuse may be the culprit as some of the other fuses i remember were charred.

 

[huttojb]

I’m not a mechanic so I’ll leave it to you mate. It was just my opinion of what I’ve seen in the past. Let me know how you get on

 

[Ragin]

Alright, thank you for the insight!

 

[Ragin]

Checked the interior fuses today, all of them were bad.

 

[Ragin]

They dont look blown but the bottom tabs are burnt. And each fuse is like this. Any idea on what could cause this?

 

[huttojb]

But did it fix the problem?

 

[Ragin]

I haven't got my new fuses yet. hopefully when i replace them all it should work. But wouldn't this be worrying if they are all blown?

 

[huttojb]

You’ll need to speak to the MIcra experts on here.

 

[Ragin]

Hey, update. I found the fusible link 60 amp popped. All my lights come on with the new battery and I replaced the popped fuses but all the dashboard lights come on, check engine, PS, anti theft, parking brake ect.

Its the 60 amp fuse that is popped and I'm sure if I replace it the car will crank? Am I right?
