Nissan Micra K12 Electric Power Steering Replacement

[@jonathanstack7231]

Hi, I'm in Cork and I'm hoping you can help me with a few questions! I have a 2002 K12 Micra with the intermittent PS issue... after 15mins of driving, the PS stopps working and the PS light comes on. When I turn the car off & on, problem goes away for another 15mins. If I replace the steering column with one fm another car: Do I need to use the donor cars key chip? Can I just disable / delete NATS!? Do I need to leave the battery connected when changing the Column? Can I install a small inline 12v battery somewhere to stop the NATS issue should the main battery every get disconnected. Is it possible to swap the old NATS receiver from the origional column into the donar column to avoid any future problems? I'm really confused by all the comments. It seems like it should be an easy fix, but I can't believe how over complicated the system sounds and how it's nearly impossible to fix. Sounds like there were two guys in the UK repairing the columns but they've stopped now.

Hi Jonathan, All very good questions and I hope that I could answer them. But unfortunately, I'm trying to find a solution to all these myself. I had done a lot of research, especially after the video and in the older nissans, you could just remove the nats chip from the ECU but don't think you can on this or at least I haven't come across any video or thread yet so I haven't tried myself. This car is still standing as-is since I did this unfortunately, I haven't been able to go at it but don't know what I'll do. My plan now is to buy another steering column which has the same part number as mine (this was slightly different) and also the one that came from an auto + fully smart key, not the one with a little button. Before I do it, I've been told to install the old one back in and try to at least start the car before trying a different column. We'll try and update here whoever gets to the bottom of it first 😅

Did you ever sort this? Having same issue

[@noorshah96]

I haven't gotten to the bottom of it yet to be honest. It's still standing there. My main fault was to try starting it with the "donor" cars key. And I've also heard that I should've left the battery connected in while doing this replacement of eps. Tried a lot of things with my scanner but seems like the ECU has blocked it any reprogramming etc. The car still won't start and I'm asking around to see if someone can sort it fore but just been busy. Will make a video once I've a good update....

[@danrus3529]

Now i will replace it without to take battery out and will work till i take battery out again

[@noorshah96]

Thanks for the tip. I actually have opened up the old PS Module but will try this to get started and follow your tip ... Also to add guys, the part I used had a slight variation in the part number so I'm gonna find the exact one for replacement

@ it works i drive the car around i go for inspection later on if you have strip them its easy to conect them from the top cover i had to remove the whole column

Will i have the same issue if the car doesnt have a smart key?

[@noorshah96]

Yes, you might if one of the car does and the other doesn't...

[@lamtransport7066]

@@noorshah96 both cars have a classic key.Do you think i can do a straight swap,or there are any things that have to be reprogrammed?Many thanks!

[@noorshah96]

I think you should be able to do a straight swap. As some mentioned in other comments that if you do the change while the battery is still plugged in etc.
