The throttle relay is in the IPDM.

Usually when the relay stops working is due to throttle body connections or the big black E3 square plug that goes to the VVEL module.

This connector holds VVEL and IPDM wiring and houses the signal to throttles and the ground for the Throttle relay.

Most likely there is a faulty connection in this connector (usually debris since it's pointed upwards)

I see you said Z1 scanned it, is the vehicle running Ecutek/Uprev?
There is some limited documented info on Ecutek/Uprev giving this issue due to software bug. A flash to stock can resolve this issue as well.

Good luck.
