Wiring to the ECM

[ForcedInduction]

I am having troubles with a wiring issue on my 2004 Volvo S60. This may sound weird but I need my car to reset readiness every time I turn the key off. There is some way the ECM keeps power for the keep alive memory but I do not see it in the diagram.

If anyone can give me a tip on what keeps the readiness values in the car that would be greatly appreciated. I will continue to search the EWD for the proper wire.

Awesome site by the way! Certified Volvo tech who ventured away from the dealership. I have a strong understanding of this car and its electrical system so please do not hesitate to speak how you would normally, no need to dumb it down.
