Hey everyone. Does anybody know if the touch sensor request PID names were renamed or changed? I've finally had the chance to wrap up installing Passive Entry on my truck and when viewing live data (oscilloscope) neither of my doors (I did both driver and passenger handles) show up. I have not done the firmware update yet.

Overview: I did the driver's door handle last fall and was able to get it to show up by observing the LK_LF_LK_TCH/UL PIDs but now it doesn't after adding the passenger door handle today and retesting (hadn't tested since last fall). Thinking it was maybe a FORScan issue I upgraded (v2.3.65) and then I couldn't even find those PIDs to listen for. Reconnecting and not loading my previous profile the closest I could find was THS_DR_LF_L/U but those don't work either.

As an aside, the driver door open/close PID does work but that appears to be renamed to AJR_DR_DRV for me.

Any thoughts?
This is interesting and I'm curious to hear anyone else experiencing this? Why would they change PIDs for this? Makes no sense.
