Yesterday this car had an issue where it was shut off for about 5 mins after a 45 min drive and wouldn't start. It would crank but not start. I noticed the D4 light was flashing so I pulled the codes. (TCU) 1, 2, 3, 7, and 8. The car sat for about 10 mins and I tried to start it again and it started and ran with no D4 light or CEL's. I shut the car off then disconnected the battery cables for 45 seconds. After reconnecting I pulled the codes once more. This time (TCU) 1, 2, 7, 8. I then attempted to start the car and it started and ran with no CEL's.
I researched quite a bit last night and came across threads on here where this happened to others and it wound up being the main relay. So I checked mine and this is what I found.

This is what I did.
And this is what I used.
Hopefully this was the issue.
