You could be correct about the ECM or even different RCDLR software. I should have qualified that all my testing has been limited to an '08 with the factory sensors. We do know that GM made model year and sometimes running changes to programming without defining what they were. You could test your sensors in the tube, by doing the same thing of reducing the pressure to 20 psi to confirm the DIC reads it and responds with a low pressure message. It'd sure be nice to know specifically what differences exist. The only other thought would be if your sensors never had the device to extend shelf life.
I'm getting close to changing tires and intend to do all sensors at that time (already past the 10 year point), so I plan to do some other tests then.
as far as I know TPMS's were not mandatory by law in 05 cars even though they came from factory with them.this may be reason for different software in RCDLR.shelf life was never an issue with originals as they are near 14 years old and still good.I will try reducing pressure if it ever warms up here to see if DIC displays low pressure message
I installed the LG Track Box and it works as advertised. Traction Control defaults to Off everytime the car is started. Also the Traction Control and Active Handling works without having Tire Pressure Sensors. All in Track Mode. The Tire Sensor light still comes on but it No Longer effects Traction Control or ABS. You can also set it back to Street Mode and use your Tire Pressure Sensor again.
LG Track Box as Shipped Installed Traction Control and Active Handling On without Tire Pressure Sensors. Yes, the TPMS light still comes on but who cares. Everything works now.

If you're not dependent on active handling or traction control, the system can be disabled by disconnecting the steering position sensor. This is the only way, besides a Track Box to ensure that Active Handling doesn't become active.

Yes
I just prefer the option of pushing the Traction Control button rather than stopping and crawling under the dash. It is pretty much how you prefer to skin the Cat.
I didn't like the experience of the ABS activating the front brakes going over 50 Mph in a curve. That pretty much made me pull the trigger on the Track Box.
