Tire Monitor Error

And have them reposition your key fob antenna too.

Already did that.

Interested: What does OVMS show you at the time of the fault?

Nothing as I didn't have it connected. I was going to update the FW that morning.

I have a TPMS error. From looking at the logs, they said it's a bad antenna. Apparently it's an easy fix. Doesn't sound like they have to take apart the dash.

Maybe, but that wouldn't cause this.

My TPMS error (started three weeks ago, still read the pressure on all four tires) involved replacing the entire TPMS control module (covered under warranty).

Quite possibly the problem and the most likely culprit. I already looked at the fuse for the TPMS, which was my first thoughts.

Really? I'm getting the exact same error message that you are, and it won't give a reading for any tire.

I've had this twice so looks like a common problem -

The TPMS error (on the 2.0 and 2.5 cars) is a common problem. I usually have to drive by the Tesla Store in LA every two months or so and have them use the TPMS tool to help the car "find" the tires again. I had a long conversation with Bob about it last week and he said the techs at corporate think the "less expensive" TPMS system they used in the 2.0+ cars has issues reading the sensors because of the carbon fiber in the car. They have no real fix except to reset the system with the tool when it happens. I've found in my car if I let the error happen for a day or two about 75% of the time it will correct itself.

I've had my rear TPMS antenna replaced twice now. Tech mentioned "a bad batch."

When I test drove a 2.5 a long while back it was triggering TPMS... I mentioned it when I dropped the car back off, and the person at the shop just shrugged like "no big deal". Yeah, I guess it has been a common problem.

Same here. Replaced rear antenna twice - it has been stable for about four months now, so hopefully they have this resolved.

[hcsharp]

The tech replaced my rear antenna today. It's inside the new rear cowling they put around the new fans in the back. Fingers crossed they have better antennas now.

Good to hear. The Rangers will be out next week to work on the TPMS. I also asked that they look at one of the fans that sounds like it has a bearing going out, and do my annual service at the same time.

[W.Petefish]

Service done. TPMS: Reprogramed.

We should start looking into making our own tool to re-program the TPMS. (Might help the rangers with a smaller tool, give open-source some more functionality, and make it easier to fix the little annoying errors like those.)
