transmitted from each active wheel sensor (not the spare tire) shall be stored in

the WCM memory.

The WCM automatically learns and stores the sensor IDs while driving "within

10 minutes continuously above 15 mph (24 km/h)" after a sensor has been

replaced. The learning sequence will initiate when the vehicle has been stopped

for more than 20 minutes.

NOTE:

A new sensor ID can also be programmed directly into

the WCM by using a RKE-TPM Analyzer in conjunction

with a Scan Tool. Once the new sensor ID has been

programmed, the RKE-TPM Analyzer can be used to

update the TPMS by activating the sensor.

OPERATION

For both the premium and base TPM, the recommended "Placard Pressure",

"Low-pressure Threshold" and "Hysteresis Pressure Values" for the tires

installed on the vehicle, are stored in the WCM non-volatile memory during the

initial Manufacturing Plant Process, or during a service procedure, as required.

To determine the pressure thresholds for a vehicle, refer to the Tire Inflation

Pressure (Placard) Label, and then apply the placard pressure to the following

table. The Low Pressure OFF Threshold is defined as the Low Pressure ON

Threshold plus the Hysteresis Pressure Value.

For further information, refer to the Owners Manual or the Appropriate

Diagnostic Information.

BASE TIRE PRESSURE MONITORING

The tire pressure monitoring system (TPMS) is designed to operate without loss

of function for all OEM tire construction for this vehicle. Sensors, mounted to

each road wheel as part of the valve stem, transmit an RF signal indicating their

individual pressure to a receiver located in the Wireless Control Module (WCM),

commonly referred to as the Sentry Key Remote Entry Module (SKREEM). On a

Domestic vehicle, the TPM sensor operates on a 315 MHz radio frequency.

Export vehicle sensors operate on a 433 MHz radio frequency. These

transmissions occur approximately once every minute at speeds over 15 mph (24

km/h). For more information on sensors, refer to SENSOR, TIRE PRESSURE
