HI,anyone got the corresponding "trouble shoot" to the engine code '54' as in i turned the srcew dial on the ECU to run diagnostics and '54' (5) and (4) flashes came up. only this no other codes.
a list off all codes would be great but just that is sufficient. cheers
ECU diagnostics?

Hopefully you'll get a consistant code "55", which is normal/all clear.

Check that TCU is definitely well seated in its socket. Run the daignostic in the FSM. How does your turbine sensor look? Any leaking? Not sure if this will throw a code.
