The operation and lamp/chime strategy of the Base Tire Pressure Monitoring

System (TPMS) also applies to the Premium TPMS, but the premium TPMS can

display text messages and a tire pressure graphic display on the information

cluster. If a low pressure condition is detected, in addition to a chime and

indicator lamp turning ON, a graphic display of the pressure value(s) with the

low tire(s) flashing will appear in the Electronic Vehicle Information Center

(EVIC). Once pressure in the suspect tire(s) raises above the Low Pressure

(lamp) OFF Threshold (see placard table below), the lamp will go out once the

WCM receives a valid transmission from the sensor. If a system fault is detected,

in addition to a chime and a indicator lamp flashing, a "Check TPM System" text

message will be displayed in the instrument cluster, and the tire pressure graphic

display will have "- -" in place of the pressure value. After the flash sequence, the

TPM indicator lamp will remain illuminated. The system will return to normal

once the WCM receives a valid transmission from that sensor location.

The Premium TPMS determines the location of the tire pressure sensors by using

transponders located in three of the four wheel wells on the vehicle. A fourth

transponder is not necessary in the remaining wheel well due to the process of

elimination theory. Once the system knows the location of the first three sensors,

it assumes the location of the fourth tire pressure sensor, and updates the graphic

display when necessary. For more information, refer to TRANSPONDER,

TIRE PRESSURE MONITORING (TPM), OPERATION .

TPM THRESHOLD PRESSURES

NOTE:

To determine the pressure thresholds for a vehicle, refer

to the Tire Inflation Pressure (Placard) Label found on the

Driver's B-Pillar, then apply the placard pressure to the

following table.
