Fuse box diagram

Hi does anyone have a fuse box diagram for the ds3 crossback? Not sure what fuse is for what and looking for any help on this. Thanks.

Fuses vary depending on engine and options, but the main ones should be in the owner manual. I don't have them for this model, sorry.

Hey, the manual is online and it looks nothing like the fuse box in my car, which is why I'm confused lol quick question telematics stereo head unit, is it a big job to get it out of car? Thanks

What's your VIN - without this I don't know what system you have. Please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff.

Ok, so you have the Connected NAC unit. What's the actual issue, as there's nothing really there to do with fuses in case that's what you're hoping to find.

But in either case the actual head unit is a separate module hidden behind the Centre Console in the dashboard. The multi-function screen is a separate unit connected to the Head Unit, which must first be removed along with the trim and screws to get into the dash.

If you perhaps explained what the problem was I might be able to advise.

Hey thank you for the info, my touch screen doesn't work, the USB sockets don't work, so as you know I can't control any functions that are controlled by this, I've been told that my head unit is the cause, it either needs repaired or replaced.. someone jump started my car and since then it hasn't worked..

Ahh, I think I remember this from a previous thread.

Did you first try a BSI reset? BSI Reset / Battery Disconnect / Reconnect Procedure

I don't have the diagrams for the fuses, so you'll have to get a dealership to advise on which one it is, as you may have damaged more than this, being that fuses rarely serve one system / piece of equipment.

A diagnostic really is needed to determine where the issue is as it may be a fuse box or associated module (or a fuse in one of those modules) that is the cause, but of course it may be either the touchscreen or the head unit that has been damaged if whoever it was reversed the connections.

[Lisawatt1976]

Ah OK, there was a diagnostic ran and no communication with telemaitcs unit was the fault, U1F3E was code...

[Lisawatt1976]

I got confused with the bsi reset as it's keyless, also asks you to turn side lights on and lock doors which I can't do if the windows down, so confused as to actual steps on how to do it...

[GiveMeABreak]

It doesn't say lock the doors Lisa, just to close them.

[Lisawatt1976]

Ah, because read unlock doors using sensor on door or fob I thought it had to be locked lol
