Steering fault light
Hi all ,my name is Nick and was wondering if someone can help me,I have used the power steering set up on a classic car with the help of some friends.
When I start the car the steering goes to the left which I know this can be adjusted but the fault light is on so have I got an electrical problem also or does the light come on with the steering pulling one way or another.
Regards

Re: Steering fault light
Hi and welcome to the forum
The pulling to the left doesn't register as a fault.
What are you using for a speed signal?

Re: Steering fault light
James many thanks for getting back to me, I've tapped and drilled the angle speed drive then added an extension that turn in sequence to the speedo ,my friend made a mini interface that reads the signal.
I don't how to post a picture but I will try to adjust the pulling and report back.

Nick - I don't suppose you could share details of the interface. James

Wiring diagrams and workshop manuals can be found at http://www.the-t-bar.com/community/downloads
I am interested in fitting a MGF steering column to one of my other cars so how you've adapted it to work on you car would be great.

Re-setting the steering column potentiometers covered here: http://mgf.ultimatemg.com/group2/common ... /index.htm
James is right: EPAS faults are not logged via the engine management system - so is not available to the vast majority (all?) generic EOBD readers. Incorrect EPAS alignment data can however be obtained from Testbook (MG Rover's own diagnostic equipment). Currently I don't believe this is possible on the pscan.eu, but I know that Phil is working on it!

Re: Steering fault light
I am long overdue with the Epas protocol; in fact I am starting to feel guilty as it is a broken promise. I am pretty sure that it will be possible to make amends by releasing the software for it by the end of this week.

Re: Steering fault light
Nice one Philip - thanks!
BTW, has anyone requested access to the Stepspeed gearbox ECU? Unfortunately, I don't have access to one of these cars myself - but it is probably one of the last ECUs on the car with no accessibility other than through Testbook (other than the conundrum that is the Pektron SCU).

Re: Steering fault light
The EPAS protocol is done, I am just struggling to test it on an actual car. I could go over to Rob's place but that will cost me at least 2 hours which I just don't have this weekend.

Re: Steering fault light
I didn't get home until after 10 on Friday! But should be back at a reasonable time one evening this week Philip, if you wanted to pop round on your way back from work?
Re: Steering fault light
I managed to test the EPAS protocol and it seems to work well.
I did the thing of revving the engine for 30 seconds to make the warning light come on.
Interestingly erasing the code would not make it go away, I had to actually drive the car to make it go away. I tried with the real T4 and it was the same with that so I don't think that there is anything I can do about that.

Re: Steering fault light
TBH Philip, the fault is still there until you drive the car.
Pleased you are making progress on this.

Re: Steering fault light
It's interesting that the EPAS fault light and the diagnostic system are separate!
What is the difference between "Main torque" and "Sub torque"? I presume that this is giving us data on the torque sensor positions (clockwise versus counter clockwise positions). If in the straight ahead position, I'd imagine that they'd both be equal values?

Re: Steering fault light
If you have a pscan.eu unit you can upgrade the software now and try it out.
