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.
OPERATION
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
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.
