I decided to go ahead and create a new thread since the 'pipe bomb' is now proven not to be a viable solution.
For a quick recap: I have 12 tires (3 sets of 4) that I change regularly and want to avoid the hassle of going to the shop to get rid of the TPMS light when I change them.
Since Subaru uses a pretty basic system that only shows if there is an issue and not independent pressure I'm OK losing the TPMS function permanently as I have the capability and knowledge to regularly check my tire pressures.
Checking with some basic info available online I've learned that Subaru uses 315 mhz unencrypted signals for their TPMS system.
I have now ordered an arduino kit along with some 315 mhz transceivers and will be working on learning some basic python for this project. I know very little coding beyond some basic HTML so this could be fun. I know these units can be programmed to mimic 315 mhz signals very easily so I'm hoping that something a little more complex is within their scale of possibilities.
https://amzn.to/2Im7XyI the arduino kit I ordered
I have also ordered a software defined radio based on the research from Jared Boone (who I have now contacted but not heard back from yet) with a lecture on his research into reading and decoding TPMS signals in Ford vehicles available here:
The end goal is to create a black box that I can run off either batteries or the cars 12V system that will send out the same signal the TPMS Computer/ECU is looking for and getting rid of both the TPMS Icon and the alert notification in the center screen.
Similar to devices like this but not offered for Subaru
This is beyond my typical scope of knowledge but I'm willing and able to put some time into this one right now. If anyone has any helpful advice please post here. An example of helpful advice would be "This won't work because each sensor transmits a unique ID that the arduino or similar system isn't capable of doing" I'll likely delete unhelpful advice such as "live with the light" "put tape on it" "this is too much work" "I'm not contributing anything towards this goal" etc as that was 2/3rds of the other thread and I just don't want the white noise in this thread.
I might also move this to electrical as it's not necessarily Gen 5 specific and also is a possible issue for those with Gen 3 and 4 cars.
Will keep this thread updated with any changes.
