Horn and TPMS

While I was tinkering today I noticed that the horn on my 2015 Tacoma has a shield over it. I removed it and it sounds better to me. The tire pressure on all 4 tires was about 23 psi and I did not have tpms light on, just curious if anyone knows what psi it turns on as I don't feel like letting air out to answer own question.

 

TPMS light depends on what the tire pressure was when it was last set. Check your owners manual.

 

The light never set. I will check manual

 

The reset sequence is something like:
Key off
Hold TPMS button
Key to on
Wait until the light blinks 3 times.

Now its set to your current pressure.

 

Thank you, so basically this system allows the driver to set his desired tire pressure.

 

Yes.
