[guaro85]

Hi guys me ? entry into the workshop this giulietta with a problem to the led daytime running lights. The problem I find when I turn on the ignition, the led of the lighthouse master start flashing, blinking for a few seconds and then go off and me appears on the display, the failure of the daytime running lights.
I have made a diagnosis on the body computer and gives me this code defect B100B feedback daytime running lights, front.
To any of you ? ever had a similar problem?
thanks a lot

hi , have you tried to do the alignment kan-bus???

[guaro85]

the can network ? all aligned

[Alessio93]

the test has to be disconnected one from the other lights??

[guaro85]

if the out point, the slave is the same defect, I tried a beacon to complete the master but the fault remains

[Alessio93]

I'm at the point I would check the points-of-mass !!! if I'm not mistaken those machines they have in the menu of body activation and deactivation of the daytime running lights !!! do one thing go to the menu undock the daytime running lights and then disconnect the negative battery terminal for 10 minutes, do the activation again and see what happens ...

hello, if I'm not mistaken there should be the drl control unit on the back of the headlight, check that and that is ok, and check the files that come in them if they are ok with the various power supplies, ? happened to jump.
