2009 Peugeot expert 9HU wiring diagram

[smokinjoe]

I have here a 2009 Peugeot expert with no comms with engine ecu,abs and no crank and would appreciate if anyone could help out with a wiring diagram, so far I have replaced bsm, checked loom in several suspect areas but no issues found, this vehicle did have rear pneumatic suspension but has been removed although the control unit is still in situ but has been programmed out of the bsi and if it's configured back to present using planet it still doesn't communicate,I have +12v and ground at engine ecu so I'm thinking a possible can issue so would be great if someone could help me out with a wiring diagram, thanks to all.

ON TOPIC:-

open hood, locate abs module, follow wiring back 4 inches, you see a thick round metal bar, look at bar, look at look, think “stupid idea, that’s going to chafe”

then, open under hood fuse box, whilst shouting out aloud
”WHAT #%$TARD MADE THIS FUSEBOX LID, WHAT A %#^}^ W@NKER”

look for blown 10 amp fuse, then press dk thanks button 50 times

Abs wiring all appears to be in good order, bsm has already been replaced twice although original was bsm r03 and have replaced with an r04 which has an extra fuse for fuel pump and a r05 which has the same fuse configuration as the r03, can anyone confirm if these are compatible. Thanks again.

Ok as for under hood fusebox we have a collection of various known fault ones, it APPEARS
to be if it “looks the same use it” but price from dealer varies from 50 to 150

not sure on that vehicle but fuel cut off switch

other though airbag module full of water
and/or diagnostic socket had them wherever pinsvopen up and no comms

Only other thing, is see if same abs as c4 because has three battery lives to it and if 3rd thin dead no comms

Ok thanks to all for all your help and suggestions on this problem which is now solved and turned out to be a faulty bsi which I didn't manage to trace the fault to carry out a repair although I suspected relay failure but they weren't too easy to access so I decided to go for a used replacement and all good.

If you mean under hood fuse box, yes once in a while you get that, relay two output to engine loosesvone

No, the first thing I changed was the underhood bsm unit as I've seen them suffer alot for different reasons but on this one it was the main interior bsi at fault which also has about 6 relays but they're not easily accessed without the use of a dremel and if not relays possibly a can driver error but I found the quickest solution was to just replace and re-program.
