2013 TSX TPMS Control Unit
I have a 2013 TSX tpms problem. Changed all 4 tire sensors with new Autel MX sensors and programmed using Autel tpms tool. It worked for a few weeks but then got a System Function Error message and a code 45-01 Initiator Circuit Short. Went to junkyard and changed both front Initiators. I can reset the TPMS using Autel tpms tool and it works. All 4 sensors show the correct tire pressure. But when I turn the car off and back on, the TPMS light flashes and I get the same error message. I have to try replacing the TPMS Control Unit (Acura 39350-TL2-A12 Unit Assembly, Tpms) Number 3 in the pic. but I don't know where its located. Behind the dash somewhere. I don't have a good illustration of where its located. I need a service repair manual that shows it. I can't exactly pull the whole dash at the junkyard looking for it. I don't know how to test electrical parts yet. I can reset it but the error message comes back on as soon as I restart the car. The fuse # 29 for TPMS driver side is fine. Anyone have a link to the service manual ?
Where exactly is the TPMS Control Unit located, number 3 in the diagram ?

I'm oftentimes having a "Really take a look at TPMS Framework" blunder come up on my 2008 TSX. It makes me insane for a little while and afterward it disappears. The proprietor's manual says the framework is off. There is no button to switch it off and afterward it reawakens in the end. In the event that it was a dead breaker it wouldn't stop until I supplanted the wire however it rectifies itself and acts for some time until it chooses to return alive. At the point when this happens I punch an adequate number of buttons on my guiding wheel to see the singular tire tensions and they are all "- - ". It isn't similar to one tire is low. I think it is the head module that the sensors on the wheels speak with some way or another loses power. Any ideas?

I solved my problem. I followed this repair guide by Honda (TPMS DTC Troubleshooting: 45) and tested using a multimeter. My control module was faulty, number 3 in the diagram I provided. I picked one up at a junk yard for around $20 and replaced it. Kinda hard to get to, high up in the dashboard. Cleared the tpms codes and tried Relearn by OBD multiples times (5) until all the IDs for the tpms sensors were written into the car using my Autel tpms tool.
Took a couple of screenshots of the troubleshooting pdf:
