TPMS Reset Procedures: Notes
NOTE:
When a tire pressure sensor or BCM has been replaced, or a wheel has been changed, retrain the tire pressure sensors.
When the tire pressure warning light illuminates and warning message appears, immediately check air pressure of all tires and adjust to the specified pressure. Both the indicator icon and the message can be cleared by adjusting the tire pressures to the recommended pressure 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 TPM sensor ID is retained but all of the tire pressure information is lost. If equipped, the driver information center will display all dashes and the scan tool will indicate a default tire pressure value of 148 psi (1020 kPa) for each tire. Driving the vehicle above 25 mph (40 km/h) for at least 2 minutes will activate the sensors causing the driver information center to display the current tire pressures. The TPM Sensor Activation Tool (EL-46079/J-46079 or EL-50448) may also be used to activate the sensors.
