EPS Power steering column, what ACTUALLY goes wrong?

#51
Hiya my phone is playing up sorry.
My car was working fine until left for 4 days without starting on a geass verge.
I started it and back tyres had locked and light came on.
Light is on permanent and no power steering atm.
I have had a few obd's on there to erase any faults but none are showing?
A airbag light was on and whilst my friends computer was on it detected thus and removed it this is now gone.
I Live in luton an could possibly drive to u if need be thanks

What a great write up about the electric PSU in the Micra. Also how great it is to find a currently active forum about the very problem you are suffering from.
As you may have guessed I had the dreaded PS light come on last week, intermittently at first and now continuously. It’s my wife’s car and there’s no way she can drive it now. I’m in Olton, Solihull, not far from the TRW factory that you’ve mentioned, and so wondered if you could help.

You continue, please tell me where your driving as I will make sure I am no where near your car!!

The NVM chip stores a lot more the fault codes,
Trim data, ECU calibration, Motor Calibration, Steering Boost Curve Data, production variance data and many more.

All NVM data are different because in production the systems are tuned to be stable. Good luck and I would take the post off because when you crash I wonder if your insurance will take this as none validated!!!

Are you an esp seller?
What can it be? Craziest thing is just steering wheel becomes hard as it has faults. There is no locking or sth else


After I read your messages I understand that YES you are an ESP seller. I AM SORRY BUT YOU CANNOT CHEAT PEOPLE ANYMORE.

Lol, you have no clue. But you crack on mate. I only help people, happy to step back and allow you to continue.

Maybe I’d share one day all that I know. I used to work with the systems and worked where it was manufactured and developed! I use the systems for another purpose and not for Micra’s.

I helped people and trust me, didn’t make a lot out of it, most times just broke even!

But as you feel your way is better I’ll point everyone at you.

I haven't replied to your message properly because frankly I was a little upset of the comment that I Cheat people. But as you think you know better I will guarantee I will not be helping anymore people out with their EPS. Like I said previously, I use the Nissan System in other applications (See here -
) like Kit Cars, boats etc.. and this gives me alot more satisfaction then giving the systems for Micra's. Unfortunately I do not have a Micra and have no interest in Micras, I helped someone, who recommended me to someone else and so on…. It was never planned. I only did this to help people. But as some people think they know better I will step back and see how many people end up in a wall.

I did use to work for TRW and been looking through a few old paperwork’s about NVM and what is configured in them, I found a few old pictures which I can share and show exactly what is in each NVM. Like I said previously, each NVM is tuned to the system during manufacturing to ensure stability of the system. I have attached the NVM contents below what I had found in my old paperwork, but there is more like Tune Data, Memory Maps for different Engine types, Maintenance Data etc... And you really think by hot swapping the NVM IC it won’t cause an accident! I hope you provide people your name so they can contact you afterwards.

The other thing I haven't even SPOKE about is removing the column and the negative impact this will have to Side Load, Absolute Steering Position, Index Position.... I can go on forever, I worked at TRW for 10 Years on the Nissan K12 System, you really think I do not know what I am talking about!!!!.... but I'm sure people will find out the issues they are going to experience. Do you really think there were no sofware updated, what do you think is going to happen if you get the NVM IC from a different Software Unit, do you really think the Configurations are in the same Memory Location....??

Your comment about there is no locking etc, I have seen it all, Self Steering, Notchy Steering, locking and freeing. but you will find this out. To be honest, I'm so set of proving you wrong, I might even Do something on my Kit Car to demostarte exactly what can happen and put it on YouTube just for you...

Anyway, signing off for the last time on this forum and will hope everyone is safe. Please please take this into consideration before doing as suggested because honestly, I am saying this for you, your family and other road users safety!

Hope everyone gets their system sorted one way or another!

When an unthinking person makes ill thought through unsubstantiated, illogical irrational comments, it not necessary to stop doing proven productive useful good work serving others!
