GM Power Modes PID for Torque Pro with 2002 TrailBlazer 4.2 LL8

Here (upper right gauge in the video) is a display of a custom PID I just created to report the current operational "Power Mode" of my 2002 4.2 LL8 TrailBlazer in the Torque Pro Android App.
The other gauges on this screen have nothing to do with this video, I just didn't have a blank dashboard to use for this video.
The "Power Mode" for this platform is determined by the BCM (Body Control Module) using several factors including the key position, sequence of inputs from the ignition switch, some serial data from others systems of the truck and so on. There are 7 "Power Modes" with this platform.
Some things to note here:
(1) The "UNLOCK" power mode exists between the OFF and ACC key positions. This is when only the ignition switch terminal E gets power. When turning the switch towards OFF this very same key/ location becomes "RAP UNLOCK" because the RAP (Retained Accessory Power) Power Mode is enabled to keep certain subsystems active for a time (like the radio, power windows,.etc.) The status of the ignition switch outputs are the same but the power mode is different until the RAP timer runs out.
(2) The RUN power mode is the same whether or not the engine is actually running. Same power mode.
(3) The "OFF/AWAKE" power mode happens when the key is OFF but the network is at least partially awake. Hitting a keyfob button or opening a door will do this before you ever put the key into the ignition lock cylinder.
(4) The "OFF/AWAKE" key position becomes the "RAP" power mode when the key is turned to OFF after having been on. Same reasons as with the RAP/UNLOCK power mode. The status of the ignition switch outputs are the same but the power mode is different until the RAP timer runs out.
The same message that reports the Power Mode also reports the status of inputs to the BCM from ignition switch terminals E (white), A (brown), G (orange), and C (pink). My next step will be to display this additional data but I am starting with just the Power Mode here.
I think this data might be useful when diagnosing possible ignition switch faults.
I have read that there may a code set when the stated Power Mode does not match the expected Power Mode. I have not yet researched that further.
