Delo357: Update: Edit: FOUND!!!
The 2011+ Scion tC 2nd edition ECU is located in the Engine Bay next to the engine fuse box. It's encased in a metal casing. Mine has the number 72 on it.

Hi all, Deangelo here from the East Coast.
I've owned a 2012 Gold TRD Scion tC2 since it came out but it got into an accident so I'm swapping all the parts over to a Silver 2011 tC2.
For the life of me I cannot know for sure if I've located the correct ECU.

The one above the steering wheel is apparently the Power Steering ECU. I'm not sure what the one under A/C **** is, so is that it?

I just want to make sure there's no corrosion or anything so pleasee help me locate and remove it!

I'm not sure if Toyota released 2nd generation repair documentation. The first generation main ECU is behind the dash, between the glove box and the passenger kick panel. Access to the ECU may require removing the glove box door and or passenger kick panel.

 

Thanks for the response. On the 2011 silver tC2 there is an empty space behind the glove box.



On the Gold tC2 which was in an accident I can see the wires which connect to what I believe is the ECU clear as day.



Either there's a major unnecessary difference between the 2011 and 2012 or I suspect the owner may have re wired it somehow..
I will also post additional picture of the Silver tC2 showing I removed the entire dash while installing the wiring harness for a head unit.



(Took out the fuse box for no reason looking for this dag gone ECU, I'm no mechanic)

Hopefully a second generation owner will chime in.
