High idle RPM

Hi,
I have a high idle rpm around 1100 rev/minute I checked following:

1) Smoke test done - no leak found.
2) TPS values checked at idle, throttle close and fully open - values are well within the range.
3) Battery is voltage is 13.5 volts. Alternator is okay.
4) IAC valve checked giving 12 volts to close valve and open valve - close and open functions respectively.

5) I checked RSC-E1 and RSO-E1 outputs and found not as per the datasheet. Please refer attached photos.

Could you please advise me how I should find the cause for the high rpm?

Last picture is the data sheet values for RSC and RSO
First picture RSC with AC.
Second picture RSC no AC.
Third picture RSO with AC.
Forth picture is RSO no AC.
