I just spent the last 2 days searching the handbook and internet for the fuse to the hazard lights on my Scudo.
No such thing apparently exists.
Then I came across a site discussing the BSI ( Body Systems Interface ) and how to do a "reboot".
I honestly thought, ( no offence to any technofiles) that this was an April fools joke.
I tried the procedure and exactly nothing happened.
So I removed the panel containing the hazard lights switch , removed dismantled and cleaned the switch, put everything back after testing it and , There you have it , the lights work.
Still don't know if such a thing as BSI exists but that wasn't my problem.
Something simple is usually the answer.

Yes BSI is the Body Computer

Daft stuff like an aftermarket stereo can upset things.

Favourite is a flashing mileage display

Glad you got sorted anyway

Nothing like premature crowing of success.
I haven't needed to use hazard lights for many months so when I pressed the button the other day,,,, They didn't work. Tapped the switch numerous times and they eventually worked . Frustrating in an emergency. Removed the switch again and tried cleaning the circuit board , replaced everything and it all works again. Anybody know what is going on ?

Now just a follow up on my prior "crowing of success". I bit the bullet and bought a replacement hazard switch from a wreckers in Lithuania on eBay. Received it within a month , replaced it in the van and it actually works . Hasn't failed because I check it occasionally. Whatever the problem it was in the switch . Sometimes some things can't be fixed , and need replacement.
