Hondata

Hi, my fn2 just recently died, engine light came on.

Towed it in, connected flashpro to read errors and it seems as if its not seeing the ecu.

USB tick, Flashpro tick, OBDII tick, ecu cross.

Obviously ignition was on. Tried a different ecu with the same results.

Tried the flashpro on my friends car, it works, tried the ecu from mine, it works.

Checked all fuses, they all fine. All earths seem to be in place. I understand this might not be a hondata problem, but what could be preventing me from reading my ecu? Car's been standing over 2 weeks now and this is so frustrating.

Any advice on what to troubleshoot would be greatly appreciated.

You more than likely have a wiring fault or a blown fuse, or both.
