TPMS on i-MiEVs

[Rational]

Continuing going off-topic, in the US we only had model years 2012, 2014, and 2016, although one member claimed he had a 2017. OTOH, IIRC in Canada there was a 2013 (and 2015?)

Back on topic, I've never had a problem with any TPMS on any of my three 2012 i-MiEVs over the year (knock on wood). All original, and still waiting for the TPMS batteries to die.

So how do you see the info on tire pressure in the factory TPMS setup? Is it on the center display or something?

The i-MiEV's TPMS doesn't provide a reading but simply results in a low pressure warning. It's one of the icons on the instrument cluster (left side) and lights up when a tire gets low (but not high). I'm old school, have an air compressor in my garage, check my i-MiEVs' tires monthly (I think the rims are very slightly porous as the pressure does drop over time), and can't remember the last time I saw this symbol. In my manual, it's discussed on Page 3-51.

I can see in MUT-3 SE read out pressure values from TPMS that are not existing of course without TPMS sensors in the tires in my case. Also i can see there to what tire pressure the existing sensors have been programmed. Also temperature readings exist.
When you do not know if TPMS sensors are working in general and you are working on trying to teach them to the car, then just decrypting the TPMS values with https://github.com/merbanan/rtl_433 is something you can do. You can also read out all the sensors from cars driving past that are also RF based.

Oh. Interesting. Can you post a screenshot or tell me where in the menus and submenus to look to find these TPMS pressure value read outs?

That will speed things up for me. Thanks.

Oh, very intersting. Great tip. I'll see about loading that up when I have a chance to see how it works and what it shows. Do you have a video on how to use it you could post and share with me to make it easier and quicker? That would be helpful. Thanks for sharing this.

Oh. Pretty basic then. Thanks for sharing that it only alerts on low and not high. Really good to know that! I like running my tires a tad high for better fuel efficiency.

Yeah, I just got an air compressor set up in my garage with the long retractable hose to make it easier to do this frequently from here on out. Way less effort now.

I have the same thing going on with my miev. At least for the right rear tire I noticed. As it seemed to be bulging after I'd inflated it the prior week. I ordered a digital pressure guage off of amazon to get them all spot on to confirm if I was just seeing things or not.

i have been trying to disable the TPMS light on a 2007 Suzuki Forenza.

Removing the TPMS control unit caused the TPMS light to blink and then stay ON solid. So there is some other controller involved in the Instrument Panel.

The FSM did not show a CAN buss connection to the control unit, and no CAN chip was found on the board. Guessing it uses the LIN buss or K-Line.

I believe that’s different on a triplet, the TPMS controller is built into the ETACs ECU and therefore communicates via CAN?

Mits tech info page indicates that there is a TPMS Off option for the outlander,

Also found a TSB related to outlander TPMS, may have some clues for miev,

Correct, there are even instructions on how to disable it on an Outlander: (link in post 25)

Unfortunately there is no such option for a triplet, maybe a bit of black tape could do the trick?
