2006 Subaru outback 2.5i wagon. Radiator Fans! ECU??

Hello,
2006 Subaru Outback 2.5i SOHC. Bought this used, trying to figure out the radiator Fans. I attached a copy of the diagram I am referring to. From what I understand, this is a FAIRLY simple circuit, if you really look into it some of it gets a little counterintuitive, but anyway, from what I understand, the ECU should recieve input from the coolant temp sensor and when it sees the correct value it should provide a path to ground for the control side of the relay on pin 29 WHT/Red wire alowing power to travel down the YELLOW/GRN wire on the load side of the relay therefore turning the fan on PROVIDED there is a good ground. I have not checked the ground for the fans yet, but, I have tried connecting the green test port under the right side of the dash by the ecu, the fans do not cycle on at all at any speed, and using the scan tool, I am not able to activate the main fan relay under the hood. "no click" from the relay. If I go to the ecu and back probe the WHT/RED wire what sort of values should I expect to see at the ecu? ~12v "FAN Off" ~0v "Fan On" and if that is not happening bad ecu? Try to help me understand what sort of tests I can do to figure this out and possibly condemn this ecu.

Can't make out a thing from your wiring diagram. It looks look like it is from your phone. Next time try www.bbbind.com/free-tsb/ & link us from there.

If you have checked your fuses & you have coolant temp readings from your scan tool, you have to check your computer outputs. Make sure you don't have power to your fans, then relay inputs & outputs, then move on to your computer. Don't judge the relays on sound alone. Do inputs & outputs & move on from there.

hi tmusser I looked at that schematic I would inspect the relay holder and connections very well I would take the diagram and trace powers and ground activations at the connection too it looks like the relays are the heart of that schematic the activation of those relays would be suspect to me but I would do a wiggle test and start by just pullin the relays out and plug them back in a few times sometimes corrosion builds up in those holders also I would look at amperages at the fuses

Yes you would see 12 volts if the ecm is not providing a ground at the time. You could backprobe pins A31 and B34 at the ecm than ground them. Just grounding A31 should give you low speed fan operation and grounding both should give you high speed.
