2018 C3 aircross schematic

Unread post by Xsmarc »

Hi all,

On my C3 the right headlamp won’t turn on. I checked and replaced the bulb and still no light.
There are no fuses for the lamp, I found 2 for the high beam but none for low beam.
With the PSA software on my PC I can turn on the left but with richt no succes.
So I guess it’s a wiring problem. I tried to find schematic diagram but no succes.
I hope somebody here can provide me a schematic diagram or give me some advise where to look for this problem
Thanks in advance
Marc

Have a look here:

According to that there is a 25A fuse for the Right Hand Dipped Beam (Right-hand dipped beam headlamp - Right-hand reversing lamps - Left-hand foglamps - Rear left-hand sidelamps - Third brake lamp).

The 80A Maxi Fuse says it's for the Left-hand dipped beam headlamp - Static cornering lamps - Direction indicator side repeaters - Left-hand direction indicators - Front left-hand and rear right-hand sidelamps - Left-hand brake lamps - Number plate lamps.

So if it was a fuse problem, I'd be expecting the other lights this fuse supports to also be faulty!

The dipped beam headlamps are controlled by the BSI, so there could be a short somewhere. I assume you've not connected any aftermarket equipment to any of the vehicle wiring???

You can always try a BSI Reset / Battery Disconnect / Reconnect Procedure
