TPM How do I correct the low tire pressure monitor after the tires are rotated?

Using the Driver Information Center (DIC)
Important: After resetting, the tire pressure monitoring (TPM) system requires up to 8 km/h (5 miles) of flat, smooth road straight line driving in each of the 4 speed ranges to complete the calibration process. For further information, refer to Tire Pressure Monitor Description and Operation . If the TPM system does not reset, refer to Driver Information Center (DIC) Switch Inoperative .

1. Set all tire pressures to the recommended kPa/psi. Refer to Vehicle Certification, Tire Placard, Anti-Theft, and Service Parts ID Label .
2. Turn ON the ignition, with the engine OFF.
3. Press the vehicle information button until TIRE INFLATION MONITOR SYSTEM PRESS (down/left arrow) SWITCH TO RESET is displayed.
4. If the system is being reset due to a low tire pressure condition, press and hold the down/left arrow button until TIRE INFLATION MONITOR SYSTEM HAS BEEN RESET is displayed. If the system is being reset due to a tire rotation, press and hold the down/left arrow button for 5 seconds.
5. Release the down/left arrow button and TIRE PRESSURE NORMAL is displayed.

I found this on another site, it may help to understand what is happening, I also saw that there is a problem with the valve stems cracking since they're made out of aluminum and causing that problem. Here's the explanation provided on another site:

If a customer with a 2005 or later DaimlerChrysler vehicle equipped with Tire Pressure Monitoring (TPM) is concerned that the TPM lamp is on continuously, please be sure to inform the customer that the system is in place to warn of a low tire pressure situation, and a system diagnosis may not be required. The customer should be aware of the following: The Tire Pressure Monitoring (TPM) System will warn the driver of a low tire pressure based on the vehicle recommended cold placard pressure (the placard is located on the drivers side B-pillar).
The tire pressure will vary with temperature by about 6.9 kPa (1 psi) for every 6.5 Degrees C (12 Degrees F). This means that when the outside temperature decreases, the tire pressure will decrease - the customer should adjust his tire pressure for this decrease in pressure - please refer the customer to his vehicle owner's manual for information on how to properly inflate his vehicle's tires. The tire pressure will also increase as the vehicle is driven - this is normal and there should be no adjustment for this increased pressure.
The TPM System will warn the driver of a low tire pressure if the tire pressure falls below the low pressure warning threshold for any reason, including low temperature effects.
The TPM System will continue to warn the driver of low tire pressure as long as the condition exists, and will not turn off until the tire pressure is at or above recommended cold placard pressure. Once the low tire pressure warning has been illuminated, the tire pressure must be increased to the recommended cold placard pressure in order for the TPM warning lamp to be turned off. The system will automatically update and the TPM warning lamp will extinguish once the updated tire pressures have been received. The vehicle may need to be driven for up to 10 minutes above 25 kph (15 mph) to receive this information.


FOR EXAMPLE:

A 2006 300 has a recommended cold (parked for more than 3 hours) placard of 207 kPa (30 psi).

If the ambient temperature is 18 Degrees C (65 Degrees F) and the measured tire pressure is 186 kPa (27 psi) the TPM lamp will be OFF.

IF NOTHING IS DONE TO THE AIR PRESSURE IN THE TIRES and the ambient temperature drops to 20 Degrees F (-7 Degrees C) while the vehicle is parked, the approximate tire pressure will be 157 kPa (23 psi) and the TPM lamp will be ON.

IF THE VEHICLE IS DRIVEN TO REACH NORMAL OPERATING TEMPERATURE

WITHOUT ADJUSTING THE AIR PRESSURE and the ambient temperature stays at -7 Degrees C (20 Degrees F), the approximate tire pressure will rise to 186 kPa (27 psi) and the 1PM lamp will be ON.

To turn the TPM lamp OFF the tires must be inflated to the vehicle recommended cold placard pressure.

In order to properly maintain vehicle tire pressure, please refer to the owner's manual for additional information regarding tire inflation.

NOTE :Tire pressure should always be set based on cold inflation tire pressure (defined as the tire pressure after a vehicle has not been driven for more than 3 hours - and in outside ambient temperature).

Seasonal temperature changes will affect tire pressure, and the TPM system will monitor the actual tire pressure in the tire.
If a diagnosis of the system is required (for example, the lamp did not extinguish, or the lamp is flashing), please refer to service information available in TechCONNECT for additional information for TPM diagnosis. Please be aware that if the Wireless Control Module (WCM) is replaced, the TPM placard values may need to be reprogrammed. The TPM placard values do NOT need to be updated if the WCM has NOT been replaced, the TPM placard values are properly set at the factory.

tire pressure monitor.tells you when your tire pressure is low in 1 or more tires

{: ) The 2002 Oldsmobile uses the TIM system. Here is an overview of how it works:
The tire inflation monitoring (TIM) system detects the differences in tire rotation speeds that are caused by changes in tire pressure. The TIM may not alert the driver if the pressure in more than one tire is high or low. The TIM also may not operate properly if the spare tire is in use.
The TIM system can alert the driver when a large change in the pressure of one tire exists. The system only detects a low pressure condition while the vehicle is being driven.
The LOW TIRE PRESSURE indicator turns ON in the instrument cluster if the tire pressure in one tire becomes 12 psi (55 kPa) lower or higher than the other 3 tires and the ignition switch is in the ON position. The message does not appear if more than one tire is low or high, or if the system is not calibrated properly. The system does not inform the driver which tire is low. In order to clear this message, equalize the tire pressures in all 4 tires and perform the Tire Inflation Monitor Resetting. In addition, the indicator may come ON if a low voltage condition is present.

In other words, this is not like the TPM (Tire Pressure Monitoring) system that is being used in later model vehicles, wherein the TPM sensors are inside the wheel, integrated to the tire valve. The TPM sensors detect changes in tire pressure and temperature, and sends out radio signals to the RCDLR, to be decoded by the BCM and the instrument cluster.

The TPM System is the Tire Pressure Monitor. Each wheel will have a tire pressure sensor that monitors the tire pressure of each wheel and send that information to a computer. If the computer is not receiving the proper information it will let you know. If the low tire light is on and not flashing than it may be something as simple as a low tire. The proper tire inflation will be inside the drivers front door on the build sticker.

If all the tire pressures are o.k. than you will need to get the TPMS scanned to see why it is not working. Chryslers are pretty common for pressure sensors to fail.

Tire pressure monitor. First check all tires for proper inflation. If 1 or more is low fill to proper psi. If all are correct need to plug into tire pressure monitor scanner & it will tell you where the problem lies. Most likely 1 of the sensors (valve stems) is faulty & needs to be replaced. Most any tire store will have the proper scanner needed.

It either has Tire Pressure Monitor (TPM), or Flat Tire Monitor (FTM)

TPM:Checks the tire inflation pressure in the four mounted tires. The system indicates if the tire inflation pressure has dropped considerably in one or several tires.

FTM:Keeps track of the inflation pressures in the four mounted tires as you drive. The system triggers an alert whenever the inflation pressure drops significantly in relation to the pressure in another tire.

TIRE PRESSURE MONITOR RESET PROCEDURE

IMPORTANT: There are 3 different ways to reset the Tire Pressure Monitor (TPM) system. After resetting, the TPM system requires up to 30 minutes of straight line driving in each of the 3 speed ranges to complete the calibration process.If the TPM system does not reset, or DTC C1245 remains current, refer to Diagnostic System Check - Tire Pressure Monitoring. For further information, refer to Tire Pressure Monitor Description and Operation.
