clutch switch problem....

[m3456y]

I'm hoping I can get a solution to an issue I'm having with my Gen2 powered Smart Car. I've got a low pressure hydraulic switch plumbed in-line with the clutch and when I put the clutch in and brake - I get a C40 code. I understand that to be an ICS valve code, but I've also found references to the clutch switch. I know the hydraulic switch is working and I only get the code under the circumstances I mentioned. Is there any work around for this? Should I go to a clutch switch from the Hayabusa motorcycle? I've tried both high and low pressure hydraulic switches and they both react the same way. Thanks in advance.

Crank it up, remove two wires to clutch switch and run it like normal if it doesn't do it after a few tries it's the clutch switch. the vibration could be making the switch act up and code happen. I had this happen on dyno yesterday and did test and no c40 code.The stock switch the contacts stick sometimes.. here is another test i ran it to redline and rolled off the throttleand let engine do the braking instead of pulling clutch in no code...

I get no code if I let engine do the br braking. I'm not using stock clutch switch, but a low pressure hydraulic switch in-line.

I have low pressure switch in-line in the clutch circuit. I know the swith is working - it opereates with 20-50 lbs of pressure.
