Hello everyone I’m new to the forum my name is Tyler and I have a 99 frc , so I got the car a little over a year ago and have not had tire pressures or key fobs working since , also have service vehicle soon and check tire pressure messages along with no comm on the rfa. I was told that it was because it needed new tire pressure sensors but that’s not the case because I’ve had my wheels on a friends vette and the tpms worked fine. Tonight I finally decided to hit it with a multimeter and see what I’m getting on the rfa plug (blk/white wire, pink wire and orange wire) . So I’m getting 12v on the orange with ignition off or on , and essentially nothing on pink. My question is could the source for the pink maybe the bcm be the issue since also my ipc is giving me problems also .

(Ipc started of about 6 months ago cycling through options by itself and now none of the buttons work but it does display everything fine. I did do an led swap on the dic buttons but don’t believe that would have caused any of these issues)

sorry for stretching that out our boys but I wanted to be descriptive to get the best help possible. Thanks in advance guys!!!

p.s trying to straighten out these issues so I can move forward with wiring up a nitrous kit 😎
