Idle control malfunction ?

[Demon_GST]

I got yesterday a check engine warning, took it to my friends garage plugged the scanner and i got a idle control malfunction.

But my car idles is ok, well i think so. (1k rpm)

Any suggestion what could be.

stock idle should be 750rpm +-50. If it's idling at any higher, you may want to adjust via the BISS screw on the throttle body. However I dont think this would throw a code. Perhaps the ISC is on its way out? I would check to see if the ISC is within spec. Although if I recall a failing ISC didn't throw a code.
