Looking for a wiring diagram — Citroën Relay X250, 2.2 HDI (CAN bus / engine ECU)

Hi all, hoping someone has access to Service Box / SEDRE or similar and could help out.
Van: Citroën Relay X250 (Fiat Ducato/Peugeot Boxer platform), 2.2 HDI diesel, Euro 5. Diagnosing an intermittent immobiliser/comms fault (U1701, U0426) and want to trace the CAN-H/CAN-L pair between the engine ECU and BSI, plus check grounds near the engine ECU.
Specifically after the wiring diagram covering: engine ECU connector pinout, CAN bus routing to BSI, and associated ground points.
Can provide VIN prefix/engine code if needed. Would really appreciate a screenshot or PDF page if anyone can pull it. Thanks in advance!

Does anyone know how I can get from Bilbao to logrono next Saturday? We are arriving into the airport by plane at 4pm but there doesn’t seem to be much in the way of transport options?
