Hey guys! I’m currently trying to figure out a way to remove the power supply control module, but cannot seem to figure out a way. Does anyone that knows what they’re doing have any tips or directions? I removed my radio as the diagram I found made it look like that was the only way to get to it, but as it turns out I can just see the module from the radio cavity I can’t actually reach it

 

I can't offer experience but suggest you do a short subscription to Toyota's TIS site (72 hours), and it will have detailed instructions on how to proceed and maybe some troubleshooting tips to confirm it is in fact the actual suspect.

Are you suffering from current draw killing the battery when off?

Have you tried removing the the passenger under panel on the dash? With the radio pulled then shining a flash light in there. It should reveal if you have access to the mounting nuts. I'm assuming it's a 2 point stud assembly.
