P0685 Code Need Help!!!

[ATLTSX]

I have a 2004 Acura TSX. I just recently went turbo. I'm running Hondata Kpro (Consides of Reflashed TSX ECU and RSX Type S ECU). Everything was running fine. A couple days ago when I was going into boost i got a CEL. The code that came up was P0685. This is ECM/PCM Power Relay Control Circuit/Open. Kpro is not showing any CEL so it has to be in the TSX ECU. I took the TSX ECU out to make sure that the Board wasn't burnt. Plugged everything back in and i got 1 run where it ran fine. Came up to the next light and it did it again.

Any thoughts? I'm trying to get this fixed to make it to IA.



Thanks.

Are you getting this error from the OBD2 port or by datalogging from the K-Pro?

OBD2 port. This code was thrown after my shop installed my clutch,turbo timer, and LSD

Could this be a blown fuse as well?

Since this happened after the Transmission was pulled out and other wiring was done, it sounds like somethign was messed up in that process. Go back and check all the wiring and try returning it to the way it was before the wiring changes were made.

Is the turbo timer hooked up to the stock ECU?
I would try taking that out of the equation first.
