2013 Transit Custom ECU problem.

[deeker]

van is back on the road. Phew.

The fault prevented the ODB reader (god knows why, as just started working once the engine was running).

Diagnosed that the signal to the PCM relay (R17) was missing, preventing this relay from energising the supply to fuses and starter relays. Jumped the relay from another ignition signal allowing engine to start and run again. Will look for permanent fix next.

thanks metalworker0 for sharing the workshop manual and to a mate who also helped diagnose and fix the problem.

Ford owners club manuals were a disappointment as i couldn't find any wiring diagrams or connector pin outs, making the diagnostics more difficult.
