Yeah, alright, I take it back. I hadn't bothered to compare the terminal numbers - they're not the same. I was working on the presumption that it was the "small plug" half of the HICAS CU because it has the same plug as the small plug on the HICAS CU. And...the drawing says "Refer to Super HICAS system circuit diagram" which seemed to place it firmly in the world of HICAS, not non-HICAS. -

You definitely have a big problem if with the adjustment screw closed up you're idling at 1200 rpm. Have you verified you have no vacuum leaks? No throttle shaft seal leaks? Nobody has messed with the throttle body set screws? I would love to see what Consult reports when your engine is idling that high. -

HICAS has a much more complicated circuit diagram, for some reason the R32 GTR service manual discusses both. The HICAS module has proper 2 way communication over consult, the "EPS control unit" doesn't have any of that and only exposes a raw analog voltage for the EPS solenoid valve. It's ultimately mostly about speed sensitive steering but the non-HICAS unit also looks at the neutral switch/brake/clutch switch to adjust how it provides assist. -

Yeah, that doesn't necessarily mean that it flows. If the exit side pipework is blocked somewhere (in the hose, in the nipple that it returns into the motor/plumbing, etc), but the supply side is not blocked, then when you crack the bleeder you will get flow from the open side. But when you close the bleeder - no flow. And.... therefore no heat. You might have to work a little harder to prove it to yourself. When I bought my engine the entire IACV bleeder was choked with cooling system schmutz. I had to clean it and the pipework out before it would work.
