Tire Pressure Monitoring (TPM)

If equipped with the Tire Pressure Monitoring (TPM) System, each of the vehicles four wheels will have a valve stem with a pressure sensor and radio transmitter built in. Signals from the tire pressure sensor/transmitter are received and interpreted by the SKREEM.

A sensor/transmitter in a mounted wheel will broadcast its detected pressure once per minute when the vehicle is moving faster than 15 mph (24 km/h). Each sensor/transmitter's broadcast is uniquely coded so that the SKREEM can determine the location.

Low Tire Pressure Thresholds:

The SKREEM monitors the signals from the tire pressure sensor/transmitters and determines if any tire has gone below the low pressure threshold LOW TIRE PRESSURE THRESHOLDS table.

CRITICAL AND NON-CRITICAL SYSTEM ALERTS
CRITICAL: A critical alert will be triggered when a tire pressure has gone below a set threshold pressure. The EVIC display will display "X TIRE(S) LOW PRESSURE". "X" will be the number of tires reporting low pressure. The message will display for the duration of the current ignition cycle or until an EVIC button is pressed. If the display is removed without correcting the condition, it will reappear 300 seconds to warn the driver of the low pressure condition.

NON-CRITICAL: A non-critical alert will be triggered when no signal is received from a sensor/transmitter. The EVIC display in the cluster will display "SERVICE TIRE SYSTEM SOON."
