Dave,

Sort of know what you are talking about. I rebuilt a damaged TK Barina a few years back. I had to replace the ECU, and I found I needed to replace quite a few modules as they all talk to each other over the CAN bus.

I think from memory I needed to swap out the ECU, the secuirty module around the ignition switch (that reads the RFID chip in the key), the immobiliser module and one other module.

Cheers,
Greg
