P0685 Code Need Help!!!
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.
