Just installed a different tire pressure display system on my F.

OBDLink LX and MX+ are 20% off Prime deals now.
Has anyone gotten the PID's for real-time tire pressure from TPMS to work with a MY 2010+?

I have OBDLink MX+ with OBDLink app monitoring a 2011 Lexus IS350C. It doesn’t show 4 separate tire pressures. It shows 2 gauges I don’t know how to read:
- Status of the 2nd tire / 4 or 5 = 4.0
- Status of the Main tire / 4 or 5 = 4.0
- Status of the Mode / Normal, Reg M, Reg 2nd or TEST = 0.0

Correct. OBD Fusion doesn't give you tire pressures. I assume status is something like ON, OFF, ERROR for those codes.

That's why I went with the aftermarket gauge.

Sorry to bring this thread back from the dead but I am looking for more insight on how to see this info. I am only able to get the (3) arbitrary status PIDs jvest got, below. I am using OBDLink MX+.

Is it possible that it depends on whether the TPMS sensors are OEM or not? I figure the PIDs wouldn't change in the Lexus architecture. Mine is a MY2010 with a manufacture date of 09/2009 if that matters.



Are you using OEM TPMS sensors?

I'll look when I get home. At the first connection page you may have to select TPMS module specifically.

Be advised I've witnessed old app data/structure since my posts.
OBD fusion has updated and in some cases improved it's capabilities. However I did notice some things go missing intermittently like Status of TRAC that I use for a 2011+ cluster swap.

Thanks for the response, I am kinda doing this in a rush because I need my new tires installed before end of July to get the rebate on them and don't want to pay to put in tpms after the fact lol.
I saw where I had to select it and tried that. If not selected, it doesn't even appear as an option. It looks like Network A and TPMS cannot be selected simultaneously which is lame. Is that true on your end?

Correct. You cannot select multiple individual modules.
Generic OBD or Network A are the ones I use most commonly since that provides the most useful data IMO.
This is common practice in most aftermarket scan tools as well (IE: snap on,autel, launch,matco etc)
The only bidirectional scan tool that allows simultaneous data to be displayed from two modules is techstream. (On all Toyota only products of course)

C.A.N. networking can become fairly complex when you start digging into data transfer.

What specifically are you trying to accomplish?

Keep in mind TPM sensors generally have a life of approximately 10-15 years.
Write down sensor IDs printed on the sensor. They're 7 or 8 letters/numbers.
You'll need a proper bidirectional scan tool to write/program them into the TPMS module.

Consider also we have the option for two sets of wheels. Main and second set, selected via the IPC switch.

I am adding a second set of wheels/tires/sensors to the car. When I bought my car, it didn't come with tpms sensors (previous owner removed them I guess). The sensors I put in the factory wheels turned the light off but were aftermarket sensors so I was wanting to verify they gave pressure and temperature before I bought the same ones to put in my second set of wheels. My current sensors are in my wheels and Discount Tire already programmed them to the car so I don't have physical access to them.

But it looks like the PIDs are not correct in the app so I am having a hard time verifying. The same information the OBDLink MX+ gave was also given by the Veepeak BLE+. I also bought the Innova 1000 but haven't tried it yet.

I wasn't aware there was a way to switch between sets of sensors, that's cool. I'll have to read about it.

AFAIK, the only reliable way to initialize two sets of TPMS sensors with the "satellite switch" is with Techstream. I had a Lexus-specific shop do mine. To be absolutely sure it got done correctly, I brought one wheel from the first/recognized set (in the trunk) so they could scan the second set mounted on the car and use the storage slot (Main or 2nd) for the ID's NOT containing the one from the first set.

It appears PIDs have been removed or simply do not populate.

As far as main or second set.
The programming process is the same.
4 sensor IDs written to main set.
4 sensor IDS written to second set. (Different than main)
Switching between Main and 2nd is done at the switch left of the steering wheel column - displayed in the instrument cluster.

Here you can see an example of my 2nd set IDs
Using aftermarket sensors & my cheap TopDon Bluetooth scan tool. (Does not write/program sensor IDs)

Damn, so it appears reading TPMS pressure/temp over an app simply will not work anymore at least using this method? Want to make sure I am getting that right.

Who decided this was a good idea 😂

Correct, the use of the app and ability to datalog (50ms) engine & trans data ( in addition to some light diagnostics) is the main reason why I recommend it.

Tire temp & pressure to monitor on the street is overkill IMO.
Other options exist for track use.

Knowing pressure is nice even for street but my IS-F will see autocross and hillclimb so temperature would be nice to know as well. I don't consider it a track car, this is my daily that will be in competition on *occasion*.

What do you think changed? I will have to see what r/CarHacking thinks about it as well.
