Now she's getting a Check Engine Light with a P1600 Code. Ref on Toyota's says it's for the following;
Is this due to more issues with the fuse block? Could it be what caused the issue initially?
- Open in back up power source circuit
- Faulty Engine Control Module (ECM)
- Engine Control Module (ECM) harness is open or shorted
- Engine Control Module (ECM) circuit poor electrical connection
Is this due to more issues with the fuse block? Could it be what caused the issue initially?
That means you don't have power to go from A to B, and to the computer. Feeding fused 12V from your fuse holder to "E" should take care of it.

Feed "E" on the fuse block with the same "E" on the relay?
I don't know what is "E" on your relay. I was referring to "E" in my picture.

Yes, I'm using your same designations for the Fuse Block and OEM Relay from your pic so all could hopefully know which I'm referring to.

I hadn't yet. I was trying to confirm that I understood you correctly before I proceeded.
I made a new connection between the fuse and "E" on the OEM relay and this time added a split-off to the "E" on the fuse box per the image below. Viola! it worked! Cleared the codes and all is good...so far. Thanks again! Really appreciate your help.
