You mean Tire Pressure Monitoring System? There is no button, it resets itself unless you have a failed sensor or some other fault. Replace the sensor or repair the fault and it relearns automatically.

 

that's correct, no reset button. If failed, simply replace the TPMS sensor (ensure correct part number), and it will re-learn by itself. Take 2-3 minute and run above 30km/h for the process to complete.

 

The sensor in the tire that shows low? Or, is there a single sensor that sees all four tires?

 

There is one sensor in each tire, 4 total. One body module receives radio signals from the sensors and sends low status to the dash for display. There are two system, the base one just lights up the warning, the higher line one displays the four tire pressures.

 

OK, thanks!!

 

Greetings, So I purchased new tires and wheels and new TPMS for my 2015 JGC, The tire dealer said my supplied sensors were correct and should work with my rig after driving a few miles. No go. Have hours of them and the sensors have not yet reset to my Jeep. I have done research and found that some vehicles require the new serial number of the sensors be written to the vehicles computer. I don't think this was done at the dealer.... Any comment would be helpful to pin down why the new sensors will not register with the vehicle. Thanks

 

Are the sensors OEM or aftermarket? Aftermarket sensors can be a problem, OEMs work much better.... if you get the proper frequency for the model year.

The Jeep will automatically reset to new sensors. There is no manual reset, but the memory can be cleared with a scanner. That is not going to fix your issue, which is incompatible sensors.

After spending hours trying to get new sensors to work, my tire shop had to pull his guaranteed to work sensors and replace with OEMs before the Jeep was happy.

 

BTW, Jeep changed WK2 sensors in 2016. So if you bought newer style sensors for the 2015, they are not going to work.
