Technical Power steering failure !!

[Owen1974]

After some advice !

This is my daughters car firstly so i cannot say if she has had an intermittent issue previously but she advises no.

It is a 2010 1.3D ]

Error code U170287 - EPS - Electrical power steering - node on C Can

I am struggling to see this code anywhere apart from one mention on here which the thread still remains inconclusive.

I have read through all the posts regarding failures and watched too may you tube videos! The steering light is permanently lit and comes on as soon as the key is turned and the engine started, i have ruled out the battery and 70A fuse as the battery has been tested and is less than a month old. The fuse tested correct when removed with no corrosion present.
I removed the battery tray and associated assemblies and removed the earth strap from the chassis to the top of the gearbox, i removed any corrosion and the sleeve and this was in a good state, other feeds advised this could be the cause owing to the amount of current drawn by the motor but i had my doubts.
Before i go and remove the steering column and get it refurbed or replace does anyone have any other ideas? i am yet to check the rack and motor, it has just starting raining again in Devon and do not fancy getting soaked

Any assistance greatly appreciated.

Hello and welcome to the forum.

Sorry to hear you're having issues with your daughter's car.

You've already done all the first things I'd suggest.

One question - does the power assistance still work even though the light is on?

1) Add a jump lead from the battery negative to a different place on the engine. (use just the negative and try a few different places)
2) Start the car
3) Is the power steering now working?

Hi Anthony unfortunately this did not work either.

I think the problem is more severe, "light is on at start up" suggests a bigger issue? I suffered pas failure twice earlier this year but that was whilst driving just after driving off , the fault cleared at restart happened twice not cropped up since

Hi

the code is U1702-87
In that format Google finds several Fiat AND Alfa Romeo... threads and videos about it

(it will be the same system components)

Hi Anthony unfortunately this did not work either.

Check the voltage across the battery with the engine on. Use a voltmeter to do this. It should be around 14V, less than that and your alternator is faulty and not suppling enough power to the power steering.

But if it reports a CAN failure it can be anything connected to the network. Aftermarket radio? Did you proxy allign woth MES?

Hello all, firstly i have found the issue so all good in that respect!
Secondly i am slightly embarrassed, i have been an engineer for 36 years in many different disciplines latterly a forklift technician. I was always taught to look at the obvious and in this instance i have not done so!
After testing the battery voltage again and the fuse correct i found it odd that the error was displayed before even starting the car, using my experience and having taken a minute to ponder it dawned on me that the CAN circuit must be broken (error code does mention this!!). So i went basic and checked plugs and wiring, under the steering column there it was a large BLUE power connector dangling in front of my eyes. Popped it back in ensured it would never come out again with a tie wrap as someone has previously broken the retaining clip, indicating this is not the first steering issue the Italian beauty has had!
Thank you all for taking the time and offering me suggestions of what to check it was greatly appreciated.

(In my defense i am now a manager and have barely picked up a spanner in anger for 5 years ✔)

I have found that the human brain can be wired up "funny"- when its been doing stuff all your life !-when you stop doing it and start telling other brains what they should be doing! your brain suddenly becomes a lazy "ar***ole and forgets useful stuff it should be keeping! then if you tell it off!- it rebels by screwing up other non-conscious controls such as making you fall-asleep at random moments, and making you want a pee just AFTER you have got in the car or gone to bed! if your google the symptoms the topic heading you get is old-age!(in my case at least!) a great indicator that my brain is turning into a form of porridge or possibly all downhill from here!
