gyislander Posted April 1, 2020 Share Posted April 1, 2020 I have a really wierd issue with my 2011 Ka tdci. When I start it it fires up instantly but the battery light stays on and the power steering doesn't work. The steering warning light does not come on and the battery is charging fine, If I switch off and restart within 20 seconds no battery light, steering works fine and battery charges as before. On the second start I can hear and feel an electric click from the electronic steering unit on the colum and another click after I switch off. Leave it more than 20 seconds and theres no click or power steering. I've cleaned all the battery and alternator connections and earths and fitted a new battery. There are no OBD codes showing or pending. The only other unusual thing is that the dash light in general seem to vary at different times as to how long before they extinguish. I've tried starting with the alternator disconnected incase its spiking but made no difference. Is there any fix possible or is it indeed a complete replacement job ? Or is there another possible cause I'm missing ? Quote Link to comment Share on other sites More sharing options...
Kevin#95 Posted April 1, 2020 Share Posted April 1, 2020 Probably the alternator is begining to fail. Brushes might be dirty due to wear and are starting to lose contact. Wierd things can start happening depending on how the car is wired. The alternator might not be able to supply both battery and power steering due to bad contact, but could appear to work charging one device. The power steering may also need the alternator to work properly, depending on how it is wired. Quote Link to comment Share on other sites More sharing options...
gyislander Posted April 2, 2020 Author Share Posted April 2, 2020 Alternator is putting out 14.2v on idle and maintains that with all the lights on too. As above, makes no difference if alt is disconnected. Quote Link to comment Share on other sites More sharing options...
iantt Posted April 2, 2020 Share Posted April 2, 2020 So when the alternator is charging at 14.2 the power steering is still not working? Quote Link to comment Share on other sites More sharing options...

Charging is irrelevant to it working or not. Issue is that on initial start it doesnt work (and battery light stays on despite charging) but restart within 20 seconds everything is fine. Its on initial start (after 20+ seconds off) that the steering ecu isnt clicking into action. Quote Link to comment Share on other sites More sharing options...
Kevin#95 Posted April 2, 2020 Share Posted April 2, 2020 If it is putting out 14.2v with the lights on then I think the alternator should be ok. Could be a bad connection on the back of the fuse box going to the alternator. A connector might be blackened and will need replacing. 1 Quote Link to comment Share on other sites More sharing options...
iantt Posted April 2, 2020 Share Posted April 2, 2020 Yeah, I was going to suggest a look at the engine bay fuse box, esp as your heater fan isn't working as that fan gets its power from the same fusebox. Quote Link to comment Share on other sites More sharing options...
gyislander Posted April 4, 2020 Author Share Posted April 4, 2020 Fan issue was just a loose connection. Tried a few different things; steering module is getting a good 12v dropping slightly on cranking. Pins on the multi plug are 12v on one and signal voltage on the rest. Car will start with the heavy +ve and groung cables disconnected. Won't start with the multi plug disconnected and shows the immobiliser red light so obviouslt the steering ecu needs signals from somewhere to work. Still haven't found a proper wiring diagram to see where everything connects. I am tempted just to put a replacement steering column in but the mystery remains as to why the steering ecu solenoid only clicks into operation at the second time of asking.

gyislander Posted April 16, 2020 Author Share Posted April 16, 2020 Put in another steering column from a breakers but no joy. My scanner wont read the car as a ford but does as some fiat models. It gives codes U1702 U0019 U0426 and U 1700. They can all be cleared apart from U0019 which it says is a B-can line wiring fault. Really need to try and get some diagrams.

gyislander Posted April 21, 2020 Author Share Posted April 21, 2020 Discovered that even if the ignition is just switched on (rather than car started) then off then started everything works ok ! Quote Link to comment Share on other sites More sharing options...
gyislander Posted April 28, 2020 Author Share Posted April 28, 2020 Interesting to find that when running but faulty, the scanner shows engine status as parking as opposed to running when everything is ok. I just need to figure out what gives the ecu the message. Quote Link to comment Share on other sites More sharing options...

You need to go to the Fiat 500 forums and ask there. 1 Quote Link to comment Share on other sites More sharing options...

Put "Fiat 500 battery light power steering fault" or similar into your favourite search engine and you should get lots of results. From what I've seen, poor battery condition, low state of charge or related issues are often the problem. Quote Link to comment Share on other sites More sharing options...
french connection Posted November 29, 2023 Share Posted November 29, 2023 did any one ever resolve this issue..having same problem even after a new alternator and new battery thanks Quote Link to comment Share on other sites More sharing options...

It is a common issue over on the Fiat 500 forum which is actually what a Ford Ka is. Just use Google and do a quick search.
