Desired Engine Coolant Temperature

[Ninety8C5]

I updated to the latest August 2018 Beta Release and there are some new tables (G0902, G0903 & G0904) in OS 12662762. Table G0902 is Desired Engine Coolant Temperature and PID GM.ECTD is a valid PID in V8 BBX but not V7 Scan Tool. When I try to log data for this PID all I get is 0. I've validated PIDs with the Scan Tool, but still no data. Is there something else I should be doing or does this mean that it just doesn't work for my OS.

Thanks.
