Having moved on from the air bag issue the EAS ECU is not communicating with the Nano. When the car arrived it had been part reconverted from springs. The ECU was loose under the seat, the delay timer was detached and the Blue/Pink and Blue/White wires had been cut.
The ECU is refixed and contacts given a clean and Delay timer reconnected and the wires soldered up. I've checked fuse 24 and 44 and they are fine so would be grateful for any pointers on where to head next. I have tested with all doors closed.
