How can I check if my ECU unit is working. My ABS and 4WS is not working and the Honda service people said my ECU needs to be replaced. How can I test it myself to see if that is the actual problem.

Absolut

You could put it in another Si and see if it works.
Sounds like a wheels sensor problem. Is the CEL on? Do you know what code its giving you?


BTW: The ecu has NOTHING to do with 4WS.
