TPMS stopped after installing VCM tuner

Correlation is not causation. Is it the TPMS system error light or the low pressure light?

My guess is one or more sensor batteries are dead, especially if the sensors are old.

Less than a week after putting the VCM tuner on our 185K 09 EX-L, we got a TPMS error code saying the system had stopped working. Could this be from the tuner? Just coincidental? Do we have to take it to a dealer to turn it back on? Tired of checking the tire pressure every time we drive it . . .

Anyone else have this happen?

Coincidence. Nothing to do with your VCM Tuner.
When was the last time you replaced your TPMS sensors? It is normal for the batteries to die after 7-8 years. I would buy 4 new TPMS sensors and have them installed and synced with your EX-L.

why do you have to check your air pressure so often?

It is the TPMS, not the low pressure light. We got well acquainted with the low pressure light when a plug on a tire started to slowly leak. This error is a new one for us.

That VCM Tuner is a powerful device. When I installed it in our odyssey, it threw a CEL in my Nissan. 😜

"TPMS" light just means you've lost communication with one or more of the sensors. The low-pressure icon (exclamation point in parentheses?) means one of your tires is reading low (via the sensor). The sensors wear out after a number of years and need to be replaced - my 2008 just finally started showing the light consistently. Of course, you're free to live dangerously and check your tires visually and/or with a gauge as we all did for +/- 100 years before the sensors and dash light existed (somehow most of us survived).

Except. If the TPMS light is ON, you can’t disable VSA.

Hello y'all.. my 2009 Touring just started the TPMS display popping up..OCCASIONALLY...
Tire pressure is good all the time.. don't scold me for trying to be cheap.. but is there a way to check and isolate each individual tire sensor that is at fault?
And while I'm at it.. is there a way toisolating the parking sesors.. having issues also... Thanks for any info.. y'all have a Blessed Day!!

With the right tool, it's not hard to isolate the problem sensor, SMA does it all the time. You attempt to read sensor IDs from each of the 4 sensors, whichever one doesn't respond is the problem sensor.
