I just purchased new tires and wheels and new tpms,once they are istalled on the wheels and on the car will they just start working or do they have to be set up will the system do it on its own,thought i read somthing like this on the fourm but can't seem to find it now.thanks

 

I beleive they might have to be programmed. Atleast thats what has to happen with other makes and models I have dealt with.

 

Search is your friend, there is a relearn procedure that requires a strong magnet on the valve stem-look it up with search at the top.

 

You'll need to program them.

 

Tire Pressure Monitoring Sensor Programming

The Tire Pressure Monitor (TPM) system interfaces with the Instrument Panel Cluster (IPC) through the serial data line. Once the program mode is accessed through the IPC, each sensor's unique identification code can be programmed into the receiver's memory. Each sensor must transmit the unique code in the proper sequence. A magnet must be held close to the sensor in order to force the sensor to transmit the identification code. The IPC will display a message as each sensor is programmed, and when to proceed to the next sensor for programming. The receiver also sends a message to the BCM to sound the horn one time, indicating that the sensor properly transmitted an identification code. If the programming sequence is cancelled before any sensor is programmed, or if the vehicle's battery is disconnected, the receiver will remember all current identification codes. As soon as the receiver learns the first sensor identification code, all previously stored codes are erased from the receiver's memory.
Tire Pressure Monitor (TPM) Programming Tool.
USE any medium strength magnet, U or Disk type
1. Turn the ignition to ON.
2. Press the RESET button in order to clear any IPC display warning messages.
3. Press and release the OPTIONS button on the DIC to scroll through the display options until the IPC display is blank.
4. Press and hold the DIC RESET button for 3 seconds.
Notice: Refer to Body Control Module (BCM) Programming/RPO Configuration in Cautions and Notices.
5. Press the OPTIONS button again until the TIRE TRAINING message appears.
6. Press the RESET button until the IPC LEARN L FRONT TIRE message appears in order to begin
the programming sequence.
7Place the MAGNET over the left front valve stem.
8. The horn will sound, indicating the left front TPM sensor is programmed.
9. When the horn sounds, proceed to program the next TPM sensor in the following order as directed
by the IPC messages:
- LEARN R FRONT TIRE
- LEARN R REAR TIRE
- LEARN L REAR TIRE
Programming Cancellation
1. The programming mode will be cancelled if any of the following conditions are met: - The program mode is exited through the DIC.
- The ignition is turned to OFF.
- All four sensors have been programmed.
- The TPM system has been in the program mode for longer than 2 minutes and no sensors
have been learned.
2. If the program mode is cancelled with less than four codes stored, the receiver will only accept the codes programmed up to that point

The Tire Pressure units in the tires have a small radio transmitter in them. They transmit 2 pieces of data ... the tire pressure, and the units unique serial number.

The radio transmissions are picked up by the RFA (Remote Function Actuator) which is a radio reciever that also picks up the transmissions from your key fobs. The data is then sent to the BCM from the RFA, and the BCM has the software that displays/alarms the tire pressure data.

When you move tires around on the car, and then go into TPMS "training" mode, the BCM displays a message to train the LF tire. The magnet you put near the tire stem wakes up the sensor and it transmits its serial number and tire pressure. The BCM then internally stores the information that that particular unit (serial number) is at the LF position. As you go round the car training the system, the BCM is simply "learning" the serial numbers of the sensors, and where they are located.

When the wheels stop turning, after a few minutes, the sensors go to "sleep" to conserve their internal batteries. When the wheels start turning again, the sensors wake up and start transmitting their serial number and pressure again. I believe they transmit several times a minute until the car has been stopped for a number of minutes (like 15 to 20).

 

WOW! that explains it really clear,thanks for the detailed reply

 

Does this come with the car or do you have to purchase one? If you need to purchase can you tell me where and what kind.

Thanks

 

try Radio Shack....or use one from any old loudspeaker (magnetic type...not, electrostatic)

 

I used the magnet on my metal parts dish.

 

It doesn't need to be that big. I used a 99 cent 1 inch by 2 inch Radio Shack magnet to do the sensors on my 97.

You may find that it takes a moment or two longer for the horn, just be patient
