DESCRIPTION & OPERATION

NOTE: The TPMS sensor Relearn procedure must be performed after every tire rotation, BCM replacement, or sensor replacement.

TIRE PRESSURE MONITOR (TPM) SYSTEM

The tire pressure monitor system uses the instrument panel cluster (IPC), body control module (BCM), 4 radio frequency transmitting pressure sensors, and the serial data circuit to perform the TPMS Relearn mode functions. Once the relearn mode has been enabled, each of the sensors unique identification codes can be learned into the BCM memory. When a sensor ID has been learned, the BCM sounds a horn chirp indicating the sensor has transmitted its ID and the BCM has received and learned it. The BCM must learn the sensor IDs in the proper sequence to determine correct sensor location. The first learned ID is assigned to the left front location, the second to right front, the third to right rear and the fourth to left rear. The turn signals will individually illuminate indicating which location is to be learned in the proper sequence.

The Relearn mode will cancel if the ignition is cycled to OFF or if more than 2 minutes has elapsed for any sensor that has not been learned. If the relearn mode is cancelled before the first sensor is learned, the original sensor IDs will be maintained. If the relearn mode is canceled after the first sensor is learned, the following will occur:

• All stored sensor IDs will be invalidated in the BCM memory.
• If equipped, the DIC will display dashes instead of tire pressures.
• DTC C0775 will be set.

TIRE PRESSURE MONITOR WARNING DISPLAY & INDICATORS

The tire pressure monitor system warns the driver when a significant loss, or gain of tire pressure occurs in any of the 4 tires and allows the driver to display the individual tire pressures and their locations on the driver information center (DIC).

When the tire pressure monitor system detects a significant loss, or gain of tire pressure, the tire pressure monitor indicator icon is illuminated on the instrument cluster and if equipped, a check tire pressure type message is displayed on the driver information center. Both the indicator icon and driver information center message can be cleared by adjusting the tire pressures to the recommended pressures and driving the vehicle above 25 mph (40 km/h) for at least 2 minutes.

NOTE: If power is disconnected from the BCM or if the vehicle battery is disconnected, each tire pressure monitor sensor ID is retained but all of the tire pressure information is lost. The DIC will display all dashes and the scan tool will indicate a default tire pressure value of 1020 kPa (148 psi) for each tire. Driving the vehicle above 25 mph (40 km/h) for at least 2 minutes will activate the sensors causing the DIC to display the current tire pressures.

The BCM has the ability to detect malfunctions within the tire pressure monitor system. In the event a DTC is set, the tire pressure monitor indicator icon on the instrument cluster will flash for 1 minute and then remain illuminated after the ignition is turned ON and the instrument cluster bulb check has been completed. Any malfunction detected will cause the driver information center to display a service tire monitor system type message.

Driver Information Center (DIC): Press MENU on the turn signal lever until Vehicle Information Menu is displayed (see Fig. 1). Scroll through the following menu items to select Tire Pressure:

• Unit
• Tire Pressure
• Remaining Oil Life

The display will show the approximate pressures of all four tires. Tire pressure is displayed in either kilopascal (kPa) or pounds per square inch (psi).
