Headlight Beam Adjustment Failure

[BENC911]

I am getting this, i think it is related to a fuse that is not working but i cannot find the fuse that covers that.

 

i had other failures but electrically they have been fixed one by one, car was in a flood.

 

ideas / suggestions?

Does the car have HID or halogen lights?  It is also useful if you post the year and model.

sorry 2011 911 carrera S, i am not sure but they are a single one

There is an angle reader on each suspension arm. I would check the wiring to each one and make sure that they are connected properly. They have a little arm attached to them. Given the history of your car take each connector off and clean it with contact cleaner as they may have rusted and shorted out.

 

 

If that doesn't work take each headlight out and check the connections at each headlight. Maybe a similar issue with a connection problem at the headlight.

 

Next would be the module that manages the system. I will see if I can find where that is. Maybe it's damaged.

 

Start with the simple stuff first. IMO

ill look on those tonight, thanks again!

I would get the car scanned with a Porsche specific scan tool (PIWIS, Durametric system) looking of the codes associated with this MIL.  These lights have a control system the operates the servo motors that move the lights, and you could have one out or just needing to be reset.  The codes will tell you exactly what is wrong.

i bought that durametric that connects to the PC, i will run that tonight and look for MIL codes, thanks

The control unit is on the back of the headlight.

I see nothing in the short report.

[Ddavidoff]

Not that I can see, but I haven't read to many of these. Have you done an inspection of the parts?

That is the only report i have, how can you get a more detail report?

[JFP in PA]

You cannot with that system.  Have you scanned the controllers?

[BENC911]

i do not know what "scanned the controllers" means, sorry I am a super newby

[JFP in PA]

Go to the "electrical" section of the left-hand menu list and look for any current or pending codes.  Do likewise in the "instrument cluster" section.

ddavidoff,

 

Tonight i will run the electrical scan as per JFP, but how can I get to these to look at them?

 

There is an angle reader on each suspension arm. I would check the wiring to each one and make sure that they are connected properly.

[JFP in PA]

As noted earlier, they are attached to the suspension arms under the car, so you would need to get the car up in the air to check them.

[BENC911]

Got it, thanks JFP

i found this picture in the internet, is this it?  If so, can you point me to the general area?

I need # 20? I thought it was 18 or 21?

[BENC911]

i am sorry i did not see your notes!

[BENC911]

this are the results from the duramtric inside instrument cluster and electronics
