hi spanz
i dont know if this will help break down the dtc  code for you in rar attachment
ive  worked on a few wagons as i was a road sweeper fitter
most wiring faults are where cab jacks up at the front and wiring into fuse board
been its had a new box they could of damaged the loom somewhere.
unless you got the workshop manual to look at ecu power and earth supply's and can wires you will be  peeing in the wind 
it does sound like ecu power fault so  id go for  them first /a power probe with the transmitter to trace wiring is the  best for this type of work /its what i use on vivaros
if i can be of help im here for you
 regards
