I have searched threads but my issue may be unique? My car has option 603 for cornering lights and they do not work. I used my Foxwell NT530 to read codes and there are no fault codes in the front control box so I'm not sure where to start? The other things probably not related is the lamps for both low beam headlights put out a pretty yellow light(maybe tired lamps?) and both are aimed down too much. Have not read anything on adjustment. I ran the turn on the lights and then the ignition switch and they are adjusting, although they never went completely off and then back on as the tutorial said they would.

Any suggestions appreciated! Thanks

 

" both are aimed down too much. Have not read anything on adjustment." The owners manual describes the aiming procedure.

 

Got it, thanks. But doesn't the auto adjustment from the 4 suspension boxes take care of this on my system?

 

I will also add that while researching this, the statement that the control box for this system often fails was mentioned numerous times. So, I was looking for a code related to the box failing and didn't find one...... Thanks
