TPMS Setting Glitch with the TAZER JL

While the warning light, chime and screen that pops up on the EVIC every time you start your engine can be annoying, I'd have to say that in spite of it, I still really like having TPMS sensors in my wheels. I mean, what's not to like about knowing what PSI you're running in each of your tires? When airing down your tires for a trail run, they'll let you know when you've reached your desired PSI and when airing up again, they'll let you know when your back up at street pressure. With all that said, I prefer to run my tires at a lower PSI than what my JL Wrangler considers to be safe and that's why I got a Z Automotive TAZER JL.

While the TAZER JL can completely turn off the TPMS warnings, its ability to lower the PSI threshold is one of many things that really got me wanting one. Certainly, running a set of Load Range E 37" mud terrain tires can feel a bit rough unless you run them at about 28 PSI and this is to say nothing about the improvement you'll see in your tread wear thanks to a flatter footprint. For my purposes, I used my TAZER JL to lower the TPMS warning threshold to 15 PSI. Being that I air down to about 16-18 PSI all the time just to soften things up when jamming down desert washes and easy trails, I figured this would be a good point to set it at. For the times I need to go lower, I figured that I could just deal with the warning chime and screen.

I should say that all this has worked out well but there has been one small glitch that I've encountered - I still get a warning even if the pressure in my tires are well above the 15 PSI I have them set at. As you can see below, all my tires are sitting at about 22-24 PSI and yet, they're still in red and I have a warning stating "Tire Low inflate to 15".

The weird thing about all this is that if I inflate my tires to 25 PSI or above, the TPMS screen reads the tires as being at a safe pressure and the warning goes off. I have tried contacting Joe at Z Automotive a few times about this and just got word today that he's out of town until the 16th.

Anyway, I don't know if I'm the only one who's seen this problem but I thought I would share why I'm seeing with all of you, just in case. I'll be sure to post up what I find out once I hear back from Joe.

Eddie- did you recently change it to 15? If so, sometimes it takes a few cycles for the setting to actually kick in. If it's been a while, then maybe try 20 or something as the threshold to see if that kicks the light off. Mine is at 27 and is fine all the way down til 22 before the light kicks on.

I changed mine to 20 and no problems. I run my tires at 30 psi. When offroad and down lower than 20 I just turn rpms off. Also did you do a full reboot after changing tpms?

Yeah, did a full reboot. May have to just set TPMS at 20.

Nah, it's been set to 15 since installing my TAZER JL.
