Low Tire Pressure Light

[Marlinmate]

Been a few cold nights lately...and jumped in this morning and the tire pressure light was on for the Right Rear.....said it was at 31psi. All 3 others were at 35.

Inflated Right Rear to 35psi, and still can't get the light to go out. Above the display, says to inflate to 39psi, which I never have done.

Is there a TPSM Reset button on the 2015 Ram Bighorn?

I just went through this and was told to inflate it to at least what it says on the dash then reduce to where you want it. The light won't go out until it sees that PSI noted on the dash. Worked for me.

Once the low psi light goes off you need to pump the tires to what the messages tells you to. You can put 35 like you did but you need to take the truck to the fwy and heat those tires up until they reach 39psi otherwise the message won't stop showing in the dash.
