вот здесь я рыл, но пока толком не нарыл
http://wwwboards.auto.ru/chevrolet/344671.htmlистория следующая, купил колеса с дисками от экалады с датчиками.
изначально была надпись "сервис тайр монитор", потом прописал датчики, машинка честно отбибикала все колеса(если бы датчик был дохлый, думаю биби бы не было) но зажгла шину и надпись "чек тайр прешша". Судя по мануалам эта надпись зажигаецца только при понижении давления ниже определенного уровня. Теперь нужно добрацца до нормального Тех2, и выставить уровни. Тот комп который был у меня в руках был только до 05 года, и с моей машиной постоянно в процессе измерений терял связь, судя по всему ему бы надо обновить прошивку. О каких магнитах народ говорит - я не понял.

Tire Monitoring System: Service and Repair
Tire Pressure Sensor Learn
TIRE PRESSURE SENSOR LEARN
LEARN MODE DESCRIPTION
The tire pressure monitor (TPM) system uses the passenger door module (PDM), body control module (BCM), exterior lamp switch, 4 radio
frequency (RF) transmitting pressure sensors, and the serial data circuit to perform the sensor learn mode functions. The sensor learn procedure
must be performed any time the PDM is replaced, a sensor is replaced, or after the vehicles tires have been rotated. Once the learn mode has been
enabled each of the sensors unique identification codes can be learned into the PDMs memory. When a sensor's Id code has been learned, the
PDM sends a serial data message to the BCM to sound a horn chirp. This verifies the sensor has transmitted it's Id code and the PDM has
received it. As soon as the fist sensor Id code is learned, all other Ids are erased from the PDMs memory.
SENSOR FUNCTIONS
Each sensor takes a pressure measurement sample once every 20 seconds while in stationary mode. If the tire pressure increases, or decreases by
more than 11 kPa (1.6 psi) from the last pressure measurement, another measurement will occur immediately to verify the change in pressure. If
a pressure change has indeed occurred, the sensor sends a re-measure transmission to the PDM. When the PDM receives a re-measure
transmission while in sensor learn mode, it will assign that sensor Id to that location on the vehicle.
SENSOR LOCATION
The PDM must learn the sensors Id codes in the proper sequence in order to determine sensor location.
LEARN MODE CANCELLATION
The TPM system will cancel the learn mode if more then 2 minutes have passed and no sensors have been learned, or if the system has been in
learn mode for more than 5 minutes. If the learn mode is canceled before any sensor has been learned, the PDM will remember all current sensor
Ids and their locations.
IMPORTANT: Before proceeding with the steps below, ensure that no other sensor learn procedure is being performed simultaneously, or that
tire pressures are not being adjusted on a TPM equipped vehicle within close proximity.
1. Turn "ON" the ignition, with the engine OFF.
2. Apply the parking brake.
IMPORTANT: If the learn mode cannot be enabled, ensure the TPM system is enabled in the PDM. Refer to Control Module Setup.
3. Turn the exterior lamp switch from "OFF" to parking lamps 4 times within 4 seconds. A horn chirp will sound and the low tire pressure
indicator will begin to flash indicating the learn mode has been enabled.
CAUTION: Over inflating tires may cause personal injury or damage to the tires and wheels. When increasing tire pressure do not
exceed the maximum inflation pressure as noted on the tire sidewall.
IMPORTANT: If a horn chirp does not sound after 35 seconds for any of the 4 sensors, turn the ignition "OFF" to exit the learn mode and
repeat the procedure from step 1.
4. Starting with the left front tire, increase or decrease the pressure for 8-10 seconds, or until a horn chirp sounds. The horn chirp may occur
before the 8-10 second pressure increase/decrease time period has been reached, or up to 30 seconds after the 8-10 second pressure
increase/decrease time period has been reached.
5. After the horn chirp has sounded, proceed as in step 4 for the next 3 sensors in the following order:
a. Right front
b. Right rear
c. Left rear
6. After all sensors have been learned, exit the learn mode by turning "OFF" the ignition.
7. After the learn mode has been exited, adjust all tire pressures to the recommended kPa/psi.

Tire Monitoring System: Service and Repair
Control Module Setup
Control Module Setup
Passenger Door Module (PDM) Setup
After PDM/Switch assembly replacement, the following procedures must be performed in the order that they appear for the Tire Pressure
Monitor (TPM)system to function properly. The PDM also requires keyless entry transmitter programming after replacement.
TPM System Enable
The service replacement PDM/Switch assembly comes with the TPM system disabled to allow the same part number PDM to be used in both
TPM and non TPM equipped vehicles. Once the TPM option is enabled in the PDM, it can not be disabled. Before proceeding with the steps
below ensure the vehicle is TPM equipped (UJ6).
1. Install a scan tool.
2. Turn ON the ignition, with the engine OFF.
3. With the scan tool select Chassis.
4. Select Tire Pressure Monitor.
5. Select Special Functions.
6. Select TPM Option Enable.
7. Press the exit key to escape.
Tire Type/Pressure Selection
Since there are different tire types and pressure combinations for different vehicles, it is necessary to select the correct tire type and tire pressures
for the vehicle being serviced.
1. Install a scan tool.
2. Turn ON the ignition, with the engine OFF.
3. With the scan tool select Chassis.
4. Select Tire Pressure Monitor.
5. Select Special Functions.
6. Select Tire Type/Pressure Selection.
7. Select P-Metric Standard.
8. Select the from: tire pressure as noted on the vehicle drivers door placard sticker.
9. Select the rear tire pressure as noted on the vehicle drivers door placard sticker.
10. Verify the selections made are correct and press the enter key. The scan tool will flash Procedure in Progress, then display Procedure
Complete.
11. Press the exit key to escape.
Tire Pressure Sensor Learn
After PDM/Switch assembly replacement each of the tire pressure sensors unique identification codes must be learned into the PDMs memory.
