Tire Pressure Indicators and Remote Start Issues

[ebland0724]

Tire pressure indicators randomly go out for all four tires; sometimes at start-up but mostly random while driving. They will work fine for a week two then they all four go out for a weeek or so, then start working again. What is strange is that my remote start quits working the same time that the tire pressure sensors stop and when they start working again, so does the remote start. I am guessing that it’s the WCM? The WCM was replaced under warranty just over a year ago due to not starting with fob, nor remote start. It’s out of warranty now, so I need some help troubleshooting...

Sounds like your body control module is whacked.

Did it throw a code?

i havent checked codes, i guess i should huh. Will it initiate a code with out any other warning light, like the check engine light etc? Cuz there are no other indicator lights on. I'll go to parts store and have them check it...

I think the WCN of that era has the receivers for both the TPMS sensors and remote start, so if the WCN is malfunctioning both could be affected. I wonder if there is a poor connection/pushed pin kind of thing going on.

I had this same problem. Ended up being a pinched wire behind the c- pillar from the factory. The tire pressure and key fob tie into the shark fin antenna.

Check your remote start antennae and its connection to the RFH hub. The TPMS system uses the remote start antennae to pick up the readings from the senders in the tires. The readings are then passed along to the RFH hub. I found this all out when I installed pushbutton start (keyless start) in my 2017 Ram a couple of weeks ago. Remote start and TPMS did not work until I reconnected correctly the remote start antennae to the RFH hub.
