When rotating the tires to a new position how does the TPMS know what position the tires are in after rotation? Can you reprogram the monitoring system?
It doesn't know the position. It knows the order in which the sensors were programmed. The normal order is driver front, passenger front, passenger rear and driver rear. If you have the sensors reprogrammed, follow that order and what you see on the dashboard should be accurate.
I base the above info on the order that my truck wanted the trailer sensors programmed, as well as how two of my other vehicles want the sensors done. I haven't actually programmed the sensors on my F-350 yet.
When rotating the tires to a new position how does the TPMS know what position the tires are in after rotation? Can you reprogram the monitoring system?
The TPMS reset and tire location training procedure is described in the owner manual. See OM v3 pages 398-401.
Since tires need to be rotated to provide consistent performance and maximum tire life, the tire pressure monitoring system needs to know when the tires are rotated
to determine which set of tires are on the front and which are on the rear. With this information, the system can detect and properly warn of low tire pressures.
System reset tips:
To reduce the chances of interference from another vehicle, perform the system reset procedure at least three feet (one meter) away from another
Ford Motor Company vehicle undergoing the system reset procedure at the same time.
• Do not wait more than two minutes between resetting each tire sensor or the system will time-out and the entire procedure will have to be repeated on
all four wheels.
• A double horn will sound indicating the need to repeat the procedure.
Performing the System Reset Procedure (Single Rear Wheel)
Read the entire procedure before attempting.
1. Drive the vehicle above 20 mph (32 km/h) for at least two minutes, then park in a safe location where you can easily get to all four tires and have access to an air pump. 2. Place the ignition in the off position and keep the key in the ignition. 3. Cycle the ignition to the on position with the engine off. 4. Turn the hazard flashers on then off three times. You must accomplish this within 10 seconds.
If the reset mode has been entered successfully, the horn will sound once, the system indicator will flash and a message is shown in
the information display. If this does not occur, please try again starting at Step 2. If after repeated attempts to enter the reset mode, the horn does not sound, the system indicator does not flash and no message is shown in the information display, seek service from your authorized dealer.
5. Train the tire pressure monitoring system sensors in the tires using the following system reset sequence starting with the left front tire in the following clockwise order:
Left front (driver's side front tire),
Right front (passenger's side front tire),
Right rear (passenger's side rear tire),
Left rear (driver's side rear tire).
6. Remove the valve cap from the valve stem on the left front tire. Decrease the air pressure until the horn sounds.
Note: The single horn chirp confirms that the sensor identification code has been learned by the module for this position. If a double horn is heard, the reset procedure was unsuccessful, and you must repeat it.
7. Remove the valve cap from the valve stem on the right front tire. Decrease the air pressure until the horn sounds. 8. Remove the valve cap from the valve stem on the right rear tire. Decrease the air pressure until the horn sounds. 9. Remove the valve cap from the valve stem on the left rear tire. Decrease the air pressure until the horn sounds.
Training is complete after the horn sounds for the last tire trained (driver's side rear tire), the system indicator stops flashing, and a message is shown in the information display. 10. Turn the ignition off. If two short horn beeps are heard, the reset procedure was unsuccessful and you must repeat it. If after repeating the procedure and two short beeps are heard when the ignition is turned to off, seek assistance from your authorized dealer. 11. Set all four tires to the recommended air pressure as indicated on the Safety Compliance Certification Label (affixed to either the door hinge
pillar, door-latch post, or the door edge that meets the door-latch post, next to the driver's seating position) or Tire Label located on the B-Pillar or the edge of the driver's door.
that I use for this purpose and it works great. I can do all four tires in less than a minute. I used it to learn the trailer TPMS sensors too. Quick and easy.
I have an Autel TS401 that I use for this purpose and it works great. I can do all four tires in less than a minute. I used it to learn the trailer TPMS sensors too. Quick and easy.
I notice it say Only provide programming service for Autel MX-Sensors - does that mean it won't work w/ the OEM (ford) sensors?
I'd love to have something like this for my Jeep (wrangler), Miata and the Truck.
Does it have to be connected to the OBDII connector to program?

I don't have this one. My interpretation is that the programming isn't actually used by that many people. My tool can't program, I just use it for activating the sensors during reprogramming.
If you read further down, it looks like it should work with just about any brand.
Mine does not need to be connected to the OBDII port to work.
I mean the oil change/tire rotation works package here at the dealership is a total of $40.... and we reprogram for you. If your time isn't worth more than the markup in that, then you probably can't afford the payment =-P

Right. The Autel is the same. It simply activates the sensor and can read the reported air pressure and temperature. There are really only a couple manufacturers of sensors, and they all work about the same.
If your time isn't worth more than the markup in that, then you probably can't afford the payment =-P
Edit, up to 5 quarts.... Still...
why don't you drink some more of that BS dealer Cool-aid....up to 5 quarts???
If it were only the time it actually TOOK to change the oil it might be worth it....BUT its the time you have to WAIT and the HIGH CHANCE that the dealer tech's will mess up more than they fix!
