Ecu diagram

Does any one have a diagram of the ecu my fans don't work I changed relays fuses even fan assembly the only way it works is if I added ground to the main relay with a switch basically the fan is on all the time, yes the temp does read so I don't think it's the temp sensor

What year G? It should be here in the FSM's, but we can't point you to the right diagrams without vehicle info.

Description of the fan system is on EC-49, ECM pin reference starts on EC-95, wiring diagram starts on EC-120.

It's a DC fan with PWM-control and not a true brushless e-Fan, so there's a good chance your Fan Control Module is simply shot.
