Tire air pressure display

why wont air pressure numbers display using maestro/alpine on 2014 tundra. Shows open doors, other engine data, etc.

 

How long has it been connected? It usually takes a couple hours after plugging everything in for my Maestro to pick up the tire pressures and temps.

 

The maestro / alpine has been installed for 4 days and still no tire pressure display. The only tire pressure display is the single icon on the dash when one or more tires have deviated from the previous settings.

 

Does it just show a dash on the HU on the tires? Do you have the OBD wire connected?

 

The ODB is connected to the Maestro app installed in the Alpine infotainment system. Other ODB related data is appearing on the gauge portion of the Maestro app display. Open doors display on the screen that also has the tire pressure status. Each tire pressure displays N/A.

Is it possible to display tire pressure numbers on the HU display for the 2014 model year?

 

Are there PIDs on that HU?

 

^ this is what I’d do next. Go to the settings menu on the HU - go into AV - then into Maestro Settings - then into Gauges - then click Validate PIDs. See if that helps.

 

OK, I will try this out and let you know the results. Thanks.

 

Tire pressure does not appear in the list of PIDs. Now I am wondering just how the TPMS works on the 2014. Alerts on a low pressure situation but doesn't tell you which tire has an issue.

Mine works fine but I installed it in a little over 3 years ago.

 

I had the same issue. I followed the instructions from the link above and it worked for me.

 

I have a Kenwood HU in my 2014 and it shows tire pressure.
It's actually my 4th HU, but all 3 aftermarket HUs showed it..
Good luck.

 

I recently had the same issue. After thinking it was aftermarket TPMS sensors, I had those replaced and still no joy. Took it into the stereo shop where I had my system installed and after a few conversations with Maestro, it turned out that one of the harnesses needed to have a resistor added for it to work. Works great now.
