Scudo 2.0 JTD 8v RHX 2002 no orange engine management light with IGN SW on, also no comms to PP2000 via OBD now.
The brown dual relay does not operate, I have already linked out the inertia switch and checked fuses. Prior to this PP2000 read faults for MAP sensor, throttle postion sensor & fuel pressure sensor shorted to supply or GND.

The ECU is a EDC15C2 0281010816 with 3 plugs and the middle plug when removed had some water in it, cleaned and dried out put back together and now ECU appears dead. (Taken ECU case off and all clean & dry inside, nothing obvious to see)

The wiring diagrams I have are for JTD 2.0 16v and don't seem to be correct pin outs to the ECU, can anyone please point me to correct drawings and help with what to try next thanks.
