I did program the sensors into the car. It'll last about ten minutes each time I do this, then it's back to the flashing then solid light. No LEDs on the car either, everything is stock. I have about $50 tied up into this, I don't feel too bad about it. Bugs me that I can't figure it out but it may be the old electrical tape trick...

Flashing then solid. I scanned it and the ECU says it can't see any of the four sensors. All of them are good. I've tried clearing it out, relearning all of the sensors. The light will start flashing then go solid 10 minutes into a drive. After that it will flash and go solid every time I start it up. I've tried that other module, same thing.

Update: Swapped the box out this morning, no problems. I didn't realize it was under the carpet, that almost threw me for a loop. I was planning on putting a new battery in the car anyway so I did the swap while the battery was out. I reprogrammed the sensors in but I'm still having the same issue. I know that the sensors are good, the tool can see them no problem and everything checks out. Both control modules being bad seems pretty slim to me. At this point I don't know what the issue could be. Looks like its electrical tape on the gauge cluster to get rid of the light...

I think the eBay one is good, for $30 I figured it was worth a shot. Seller said it was working fine... I've read about people doing this to solve the winter tire light issue so I was hoping the swap would be easy. Good to know about the seat too, I'll take a look under there and see how easy it is to get too. Thanks for the replies.

I've done some searching and can't really find a direct answer to this... I have a 2009 Legacy 2.5i that has had a flashing/solid TPMS light for a couple years now. Last year I had the sensors scanned and found a dead one. Replaced it and the light stayed off for a couple days then came back on. Figured more were dead so I would just replace them all when I did the tires again. Fast forward to last week. Replaced all four sensors with brand new Subaru units. They programmed fine but the light came back on after about 10 minutes of driving. Now its doing the typical 'flash when I start the car then go solid' every time again. All sensors scanned fine, reprogrammed them again and got the same thing. I figured it has to be a bad TPMS control module. I bought one off of eBay to try, part number 28201AG06A. I can't find much info on swapping this unit out. I know that its under the drivers seat but I've read about the modules in other models being tied into other systems and causing issues when they're unplugged. I've also read about issues with the weight/airbag sensors in the seat needing re-calibrated when the seat is removed. Does anyone have any info on what I might be getting myself into if I pull that seat and swap that module? Thanks in advance.
