Not a real solution.. only a workaround.

Re: HELP my Power Steering Light is ON! - Start here!

when my power steering failed i looked it up and i found out that the power steering motor are attached to 2 relays.

All good as new
Look up the relay names to be certain

Re: HELP my Power Steering Light is ON! - Start here!

I have the PAS problem on my 2004 Punto 1.2 8V. It seems to happen at random, but usually after long periods of not being used- restarting the car and simply driving it appeared to be a temporary fix. I have checked the condition of all the connections between the battery, the alternator and the steering column and they are all fine, and the voltage across the battery reads 14.2V (drops to 13.9V under loads such as heater and lights on), but the problem persists. What could the cause be in this case?- been thinking it might be a less-than-perfect battery but I would like to be 100% sure before sorting it out.

Hi. A good charging circuit is crucial.

I had a sporting that needed revs to get the power out of the alternator at cold.

Re: HELP my Power Steering Light is ON! - Start here!

Hi to all Punto mk2 followers….

Newbie to the forum by several weeks, owner of a Mk2 1.9 JTD…….have been reading up on the EPS issues threads to understand the various common issues.

Have had an Intermittant EPS warning light ongoing for 12 + months, transitioned last month into a permanent warning light. Throwing EPS ecu codes C1012 and C1013, Multiecuscan software testing:-
- Vehicle speed signal from CAN reading 60kmh when ABS module shows it as 0.0kmh at stationary
- Alternator status from CAN ‘not recharging’ when alternator charging at 13.9 to 14.3 volts

Since both of the thrown codes are CAN related, I started with static tests on the OBD plug,
CAN H against CAN L = 22.75 k ohm ignition off, no where near the 60 ohm expected.

Checked earth leads and ground points:-
- Earth leads……(battery to chassis, chassis to gearbox, multi loom earth next door to chassis earth, 1 below ABS box to wheel arch, 1 below bonnet release, multi loom earth in boot)
- Uncouple and recouple gang plugs on key CM’s, using some contact spray to assist

Started to identify the different control modules intending to follow CANBUS wiring and do an isolation test on each module to try and isolate down to 60 ohm, came up with:-
- Main ECU (windscreen valence area of engine bay)
- EPS ECU (Steering column)
- Airbag CM (floor mounted centre tunnel, under dashboard)
- ABS ECU (engine bay, passenger side firewall)
- Integrated ECU / Fuse board (drivers right knee)

I am struggling with the following questions:-

1. Not sure about relevance of Dashboard clocks…..yes in Canbus loop but are they a Control Module
2. Fuse box in engine bay, looks like a straight fuse box despite the gang plug connections on the back.
3. Struggling to get a good wiring diagram for Canbus for the 1.9 JTD, particular CANBUS wiring colouring for CAN H and CAN L loops
4. Struggling to understand which CM’s are fitted with termination resistors, so I can target the additional ones 1st. (I am guessing but would opt to Main ECU and Integrated Delphi Unit & Fuse board by drivers knee)

I would welcome any suggestions about C1012 and C1013 fixes apart from follow up on the above.

Many thanks

Дорогой друг. Эти реле можно пропаять и все заработает.

Приветствую. Не менял части, ничего нового не вставлял. Все стоит отремонтированное. Авто 2001 года выпуска 1,2 16v. Реле паяльной станцией паять нужно и все контакты на плате. Также пострадал датчик положения рулевого колеса. Я его разобрал и починил.

Re: HELP my Power Steering Light is ON! - Start here!

Hi,
I have got same problem with my 53 plate punto.
Power steering goes off, I read errors and I have got both c1005 & c1006, delete them and recalibrate angle sensor but problem appears again.
Car have got new battery and alternator is charging 14V even with main beam on.
Anything I should check before replacing steering angle sensor?
tia
