TPMS Problem
I did a quick search and couldnt find any answers so hopefully you all could give me some insight.
I took out the spare tire in my LS since I now have 22s and I redid my audio set up which now has the amp in the spare tire well. However, after they installed my new system I was driving and I now get "Check Tire Pressure System" At first I thought my rims had a flat but Im pretty sure it was because I removed the spare and its only reading 4 wheels now. I took it to the dealer and a tech said no way to remove the light on my dash, but I think there must be some way?
Having an 08 600 my trunk is really small so having my big amp in the wheel well saves me some space and looks very clean.

That shouldn't have triggered it. If the car doesn't see the spare it just won't register it on the cluster. Try playing with it. Put the spare near the car and see if it'll go away.
it will trigger. absence of a (or all) tpms from the 5 programmed ones and it will trigger system error code

If you started in your garage with one sensor not reporting then you would have 4 pressures displayed and the fifth sensor would show "checking" until you have driven 30 minutes and then system alarm.
A flat tire is not a non-reporting sensor - it is a sensor reporting a low pressure.
Unfortunately I think the only way to work around this is to have the TPMS "bomb" made to trick the sensors (https://www.clublexus.com/forums/3173139-post1.html)

TPMS bomb for sure..you can get a used sensor part # PMV 107J from ebay for real cheap and follow the instructions on how to make the device to put it in. Discount Tire might be able to program that one sensor in the tmps bomb back into the car on the cheap...or if you can have a shop scan the sensor ID of the TPMS, you can contact Orange TPMS and provide them that ID code so they can send you one of their sensors pre flashed with the same spare sensor ID ..that way you don't have to worrry about reprogramming if you can't get that done for free..just a thought
I guess i was wrong. Question...do your wheels have dual valve stems? If they do you can install your spare tire sensor on the second valve stem. Not sure if your wheels do. I know a hand full of wheels i was looking at had 2 for nitrogen filled tires. One is to fill and the other is to bleed out regular air.
