The car is running fine otherwise.

So far it looks like only US and Canada Yaris have the cruise functionality built into the ECM. In the UAE do you get European Yaris? If so, cruise is definitely not built in.

The part number on my ECM is 89661-52C00

I would say that there is a good chance that that ECM doesn't have cruise control, as that part number is not a USDM/CAN one and so far it appears that just ECMs for those markets have the functionality. One test that you can try is to measure the voltage on pin 40 of the ECM connector A21, with the connector in and the ignition in the ON position. If you measure +12VDC to ground on that pin, then there is a good chance that your ECM supports cruise. If you measure 0 VDC to ground, then it definitely does not.
