hi all new to the forum so be gentle
sorry if this is a bit long winded but i will explain best i can
ok friends 06 punto had engine check light on so plugged in my code reader after problems connecting messing with fuses i find the lighter fuse blown i swap this with window one and cleaning sensor contacts i see on dash coolant temp warning although engine not overheating so i think temp sensor . plugged code reader in again and now connects and pulls the following codes p0115 engine coolant temp circuit p0615 starter relay circuit and u0001 i clear codes but they keep coming back. i look at live data and its not showing as running hot. then it wont start as if there's not enough power in the battery just starter solenoid clicking so i check battery voltage fine then go back it starts fine every time i test the starter craning volts fine i conclude starter relay so i keep removing each relay in turn till i find the starter relay and swap it with another relay. i know go to check codes now all cleared but i have a power steering fault with no codes red warning light and wording on dash. so i disconnect battery for 5 mins retry no ecu fault codes but still steering fault steering performs normal . so is the original fault likely to come back ? how do i clear original fault? i should add i disconnected a few wires while investergating any help greatfuly received

bump anyone? also is there a cheap code reader that will read the power steering ecu and reset ? assuming there is no simple trick to turn light off steering seems to work but light is still on
 
Seriously though, I can't really offer anything constructive, but I strongly recommend you steer away from your mates car until you know what you are doing. And I don't mean that in a derogatory way.

Pulling out wires and relays, generating additional faults, clearing faults without investigating the cause. That's just shooting in the dark.

Did you keep notes so that you can "rollback" your changes? I can't imagine your mate is very happy....

well to imply im dense and don't know what im doing is rude you don't know me or my abilities. dose this forum not help people of all ability's?
i don't know what you call it but i call it fault finding i can most certainly can retrace everything i have done. i located the faulty starter relay. i did not remove any wires from the power steering but i assume in the possess of identifying said relay ive removed the power steering relay hence the power steering warning light so il give you that one
as it happens the light has gone and so has the ecu light
so i need to replace starter relay and i assume the temp sensor code will need a new temp sensor i dont know what the other code means i had thought somebody on the forum may help

ok friends 06 punto had engine check light on and random no start so plugged in my code reader after problems connecting checking fuses i find the lighter fuse blown i swap this with window one and cleaning crank sensor i see on dash coolant temp warning im told this has been coming on for a while although engine not overheating so i think temp sensor . plugged code reader in again and now connects and pulls the following codes p0115 engine coolant temp circuit p0615 starter relay circuit and u0001 i clear codes but they keep coming back. i look at live data and its not showing as running hot. then it wont start as if there's not enough power in the battery just starter solenoid clicking so i check battery voltage fine then go back it starts fine every time i test the starter craning volts fine i conclude starter relay so i keep removing each relay in turn till i find the starter relay and swap it with another relay. i know go to check codes now all cleared but i have a power steering fault with no codes red warning light and wording on dash. so i disconnect battery for 5 mins retry no ecu fault codes but still steering fault steering performs normal . so is the original fault likely to come back ? how do i clear power steering fault? do i need a tool or is there another method i should add i disconnected a few wires while investergating to check for corrosion any help greatfuly received

reworded to make it more understandable
 
I wasn't implying you were dense.
And the forum is excellent for all levels of abilities, including fairly novice like myself.

But reading codes, then clearing them, then wondering why they come back, without identifying what caused them, and in the process, apparently triggering additional problems...I don't call that fault finding.

I'll duck out at this point, I have nothing constructive to add. Well, maybe one thing. The ELM327 only connects with key in position 1 or engine running. It's easy to forget.

wasn't sure what you ment buy dences brain dumps thought you implied i was dence.
as for clearing codes past experiences tells me to make note of any stored codes then erase them and see if they come back i could be looking at stored codes not been cleared from 3 years ago or when ever and looking at problems that have been fixed
the codes came back hence why i asked on the forums . yes i may have caused the steering fault but the other faults were already there hence why the ecu light was on and my friend having difficulty starting.
experience also tells me i need the ignition on or car running but thanks for the info and just for the record the leads or wires were not disconnected with the ignition or engine running so they would not have caused further fault codes perhaps my method of finding the starter relay was a bit silly

P0115 is either coolant temp sensor or check the coolant level 9 times out of 10, coolant is low. Had that on a friends Punto today (y)

first thing i checked thanks so looks like it could be an intermittent temp sensor
one thing i did notice is on start up the temp gauge shoots up into the red as far as it goes then comes back to what appears to be the normal range not sure if this is normal self test or not thanks
 
the power steering light sometimes comes on if battery low with say ignition on and messing with code readers and doing stuff
i would suggest you recharge your battery and so long as battery and cabling and alternator tickety boo your warning light will be history
this is for 2006 model and going back to first of facelifts ie 53 plates

It appears that the steering warning light has cleared i checked the battery with my load tester it it had a cca of 300 and on the battery sticker says 390 so it would seem fine just panicked when i couldn't clear the power steering light
thanks

I haven't driven my Mk2 for a while now so I wouldn't be able to say for sure but it doesn't sound like it should do that anyway. On my Grande Punto it just stays as it is until it starts warming up and then goes half way gradually
