Bsi issues peugeot 3008

[Projay11]

Im having an issue where the boot thinks its permanently open so wont lock but also I have none of the interior lights working when opening doors. All reading, sun visor lights work just not main ones.

Its a 2014 peugeot 3008

Its bsi04 ev k01-00 071113

Can provide the vin if needed. Ideally looking for some guidance to where to look on the bsi as csnt find any information

Have you checked that it is not just a problem with the boot switch? Maybe try bypassing it?

With the boot open close its lock around a screwdriver to see if it is the lock or the boot not fully closing - on our Cactus the tailgate seal sometimes comes off a bit and stops it closing fully enough.

Have you checked if the inside lights are turned off on the switch ?

I have tried bypassing the switch by shorting cable 6283 to ground. Ive also tested the actual microswitch itself and it seems to be working fine. The cable from the rear pillar to the lock itself is also fine.

I wanted to ideally test the route from the rear pillar directly to the bsi but so far not had any luck finding the cable in the front of the car

Some more information. After using diagbox the bsi thinks all doors are open not just the boot. Also the hazard light switch is broken

[moizeau]

Fake a door closed condition with the doors open using a screwdriver to flick the latch. If it then locks, try each door at a time to narrow it down.

Ive tried that still nothing, my assumption currently is one of the bsi wire has either broken or a ground somewhere is broken.

Does anyone happen to have any diagram I can use i have the one from haynes but is not great
