Title: Xenon headlight problem?
Post by: rogerreno on 16 November 2006, 21:40:04
After finally picking the car up on Tuesday I noticed something that didn't seem right.

After starting the car up the multi function unit displays 'Headlight field/vision'

Is this related to the self levelling system for the headlights?? Coz my Dad thought it was because a front sidelight bulb had blown!!!

Now I know the systems going to be different to my old Espace,but the Xenons on that used to drop to the lowest setting when you'd turn the lights off,then when you turn them back on you would hear the motors operating and see the lights raise up to the correct level.

On the Tractor i've not seen them move or heard the motors adjusting them,is this related to the above display??

And if so,is there anyway of doing the 'paperclip test' to determine which sensor is faulty??
Failing that,can the sensors be tested with a multimeter for resistance??

Thanx in advance..

Correct, related to headlamp levelling.  Need to read codes to find code, cannot paperclip it. Need a code reader that can read headlamp codes....

And I don't suppose you'd happen to know someone that has a code reader for headlamp codes do you.... :y

Mine does the same thing.  TB read the codes twice.  Next step is to take assy out and try to free up motor.  Mine is pointed straight at the ground, so obvious even without codes.

Does yours display the fault 'Headlight Field/Vision' as well?? And if so,what fault did yours come up with??
Or is it that your adjusting motors have given up??

Yes.  The error codes were about the voltages at the motor.  Unclipped the plug and gave it a good clean.  Got different but similar error codes.  The expectation is that the mechanism is stuck.

Perhaps I'll have a quick look at the weekend then,may just be a bad contact....

Following on from the suggested fault I removed both the front and rear level sensors for the headlight system to find that the balljoints and links on both sensors had corroded and seized.

I freed off the balljoints and then took the top (the lever arm) off both sensors and made sure they moved freely.

Put it all back together and..........STILL NO SELF LEVELLING  :( and 'Headlight Field/Vision' still on the display  :(

If one of the sensors was faulty,would this stop the good sensor from carrying out any adjustment and put it into a 'safe' mode?? Coz the headlights are nice and bright,its just that they are incredibley low which in turn doesn't really light the road up  :'(

Mr Theboy...is your diagnostic tool able to tell me which sensor is faulty and if so are you able to look at it for me?? Please!!  ;) I'm going to be about later on on Thursday this if thats any good???

Want to get to the bottom of it and get the headlamps working as they should.

Cheers

Yes, fault with one sensor, or the motors in the headlight units will put them low...

Tech2 will show why you are getting the error...
