tire rotation - sensors

[ToddGeisler]

My 2015 has a little over 6000 miles and is due for a tire rotation.

Is there anything special that needs to be done so the truck still recognizes the proper location of each tire/sensor after swapping the tires around?

I checked the owners manual and could not find anything.

Just curious how the truck recognizes each sensor and it's location. Is it a code/signal per sensor or does the ABS sensor somehow come into play helping identify the wheel speed on each corner.

Also, I remember seeing a thread where some ran less than 80 lbs in their back tires. How do you get around the dash alarm flashing. I just had a nail in the right rear tire fixed this afternoon and the system didn't want to allow me to run 65 lbs in the back...kept flashing set to 80 lbs.

It will figure out which tire is where. Takes a few miles usually. I think it does it by signal strength.

If you run lower pressures you have to get used to the warning. It barely bothers me anymore

I rotate my spare with the others. If you do that, it is always confused

My truck is really confused as I did not order any sensors for my new wheels and tires. I only have the sensors in my winter tires which are the stock tires and wheels. The truck goes ding and the low pressure warning is on.

Tire Pressure Monitor System - The RFHM is an RF receiver that monitors RF signals received from the Tire Pressure Monitor (TPM) sensors and relays the appropriate electronic messages to other electronic modules in the vehicle over the CAN data bus to support the features of the TPM system.

The battery operated tire pressure sensor is both a transmitter and a receiver. The TPM sensor can be forced to transmit if using a special tool such as a TPM-RKE Analyzer. The TPM-RKE Analyzer has the ability to change the sensor mode and to diagnose a faulty TPM sensor. Using a TPM-RKE Analyzer can take up to a minute to force a transmission from a sensor.

Each sensor’s (transmitter) broadcast is uniquely coded so that the module can monitor the state of each of the sensors on the four rotating road wheels. The module can automatically learn and store the sensor’s ID while driving “within 20 minutes continuously above 20 m.p.h. (32 Km/h)” after a sensor has been replaced. The vehicle must be stationary for more then 20 minutes in order to initiate the learning sequence.

The sensor IDs can also be programmed using the TPM-RKE Analyzer Tool. Scan each TPM sensor at each road wheel, and store each Sensor ID in the correct location. (LEFT FRONT, LEFT REAR, RIGHT FRONT, and RIGHT REAR) Connect the TPM-RKE Analyzer Tool to the Scan Tool. Then follow the programming steps outlined in the diagnostic Scan Tool for “Program Tire Pressure Sensor ID w/ TPM Tool”.

Good info. How long do the batteries last in the tire mounted sensors?

plan on 5years some do better some worse

It might be an apples/oranges comparison but I just had to replace all of the sensors in my wifes 03 Jeep GC a few months ago...12 years is pretty good in my book.

Is there a way to just turn the system off?

 

[Newsa]

It's now required by law to have operational TPMS in passenger cars. Not sure if heavy duty trucks fall under that category. I know there's and exclusion for HD trucks in EPA fuel mileage. Not sure about TPMS. Can turn off the audio on the seat belt warnings, but not the light on the dash.

I just look at my tires before I get in with the 99. I have enough things nagging me without the truck doing it also.

I am afraid not

I got a spare matching rim with TPS so not a problem
