Diag code DF074 - Steering wheel angle coherence

[denisb]

Hello Guys,

after the power steering rack replacement (taken from PH1 172) i got ABS , ESP and service lights showing up.

in the past i had ESP and Serv lights up occasionally about once a month, that were cleared by turn off and on the car.

At the dealer shop, they found that there error code that can't be deleted (it's comming up again) DF074 Steering Wheel angle coherence.
They checked the wiring and found that one of the pins of the steering wheel angle sensor not getting electricity (Pin 1 if i remember right). So they told me to replace the ABS computer and pump. it's very expensive part as far as i see, and i am not sure that this is the problem.

Right now the situation is next, when i turn on the car no lights coming up, even i if am driving for couple of meters in straight line with no steering wheel movement. Once i moved the steering wheel the ESP and SERV lights coming on and staying till the car turn off.

Anybody has any idea on this issue? Can it be the steering wheel sensor?

Common issue when racks are changed incorrectly this and changing the ABS/ESP computer will not fix the problem! If there's no +12v after voltage then the wiring and all insulation should be checked BEFORE replacing the control units as they're not cheap.

I don't know what the garage has done already but firstly, the steering wheel needs to come off and the SAS setup inspected as chances are its not central. If it isn't, the setup needs centralising and the code clearing. If it is, the car needs to go to a dealer or specialist with a CLIP to have the SAS re-configured by running VP003.

thanks for your response,

the renaul dealer checked the wiring and there is continuity at all wires coming to the sensor from the ABS unit.
During the rack replacement the steering wheel was untouched, and only under the car part was replaced.
Do you know if the PH1 (2001) power steering rack suits for the PH2 (2003) cars as well?

Is there any procedure how to align the SAS? anything that i can do by myself?

in addition in the garage they tried to run "learning" for the steering and it not worked. in addition the value showing degrees of the steering was around 80000 or something like that and not changed when you moving the steering wheel.

Nope, you cannot touch anything on this system yourself i'm afraid and the SAS can only be set by running command VP003 on a CLIP (Which is the Renault dealer tech tool). So am I correct when I say a franchised Renault dealer has carried out this work for you and not a specialist or an independent garage?

I personally suspect 'they' have most likely done something to either the column alignment or the SAS unit itself during the replacement procedure. I've seen it on the Laguna II's before where the setup has been but a few degrees out which the SAS interpruts as a genuine fault. As the steering angle value itself is not changing it says that there's either a comms unit fault (This is the main control unit at the steering wheel that holds the SAS, Indicator stalks, SRS lines, Etc), there is a wiring fault between the Comms Unit and the ABS/ESP Unit or finally, the ABS/ESP unit itself has developed a fault.

Now if the wiring has been confirmed as being okay then the components need testing/replacing accordingly and I'd start at the SAS ensuring continuity between the pins on the Comms unit and those at the very end of the clockring.

anybody knows what is the part number of steering angle sensor fro 2003 Clio 172?

mate, if they have done the work on the car and it was fine before, surely they should foot the bill on this :S

I'd need your full VIN to be able to work that out as I need to find out equipment codes, tech features, etc and you shouldn't post that on a public forum.

As Jonny said above, if a dealer has caused this issue then it should be down to them to rectify it

Hi,

I sent you PM with chassis number , could you please check part number for me?

Sorry for bumping an old thread..Does anyone know the part number for the SAS on a 2003 172?

Hello

Sorry for use this old topic, but i have a similar problem with my clio dci with ESP.

I have this error DF074. I can clear the error with renault can clip, but when i turn the steering wheel with car running in some speed, the light comes on and the error comes (with red signaling on clip)

I have check the presence of 12v from key in terminals 1 and 5 from steering wheel sensor and it's OK. I have check the continuity and insulation of this wires to the ABS pump and it's OK, i have check the continuity from terminals 3 and 4 from steering sensor to the multiplex wiring, and it's OK


I can see perfectly the value of steering wheel angle with can clip, even when i turn the steering wheel. I have configured the steering angle to zero point and it's OK...

So... the ABS unit is faulty? or something is missing to me? please help me...

Goog Morning was urgent help in solving the above problem by Xmarine are with the car stalled since November 2013 and it is urgent for the right car to run please help ... thanks

Hi,

I know this is an old topic but, how did you manage to a SAS zero point calibration using the CAN Clip? I have the same issue and the SAS on my Clio reads 81918

Hi,

I know this is an old topic but, how did you manage to a SAS zero point calibration using the CAN Clip? I have the same issue and the SAS on my Clio reads 81918

First of all I’ll say that I’m definitely no expert and it may be pot luck, but I think I’ve rectified this issue.

I had a SAS which read -81000deg, and have gone to the lengths of buying a clone clip, and old laptop. Using VP003 recalibration wouldn’t reset the SAS, however I had another SAS which constantly read 135 deg, and I was able to reset this using VP003. I had the car running for the 2nd SAS, I don’t know if this made the difference.

Anyway I’ve been running up and down the long drive we have,and the ESP and SERV lights stay off, and the angle is now changing on clip and iCarsoft RTII

Having wrestled with this problem a long time I would advise the following:

1. The iCarsoft RT II cannot calibrate SAS on a clio 1*2 (2003 onwards)
2. Go to a specialist if that’s you can. The only reason I’ve persisted myself is that I got the car cheap, and I live in the north of Scotland, where we don’t have any independant experts on these. The dealer was an option but still 50 miles away to trailer it and £££. Also, installing the clone clip etc is such a pain imho.

Like I say I’m no expert, and it may return, but right now it looks like the SAS is doing what it should, whereas before it wasn’t.
