WARNING: This page is about a different car, the 2004 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

Left Front Wheel Speed: The scan tool displays 0-255 km/h (0-159 mph). The actual speed of the left front wheel.
Left Rear Wheel Speed: The scan tool displays 0-255 km/h (0-159 mph). The actual speed of the left rear wheel.
Right Front Wheel Speed: The scan tool displays 0-255 km/h (0-159 mph). The actual speed of the right front wheel.
Right Rear Wheel Speed: The scan tool displays 0-255 km/h (0-159 mph). The actual speed of the right rear wheel.
Speed Range 1 Calibrated: The scan tool displays Yes or No. Yes indicates speed range 1 is fully calibrated and the TPM system has full tire pressure detection capability from 31-65 km/h (19-40 mph). No indicates the TPM system is in the calibration process in speed range 1 and has no tire pressure detection capability in speed range 1.
Speed Range 2 Calibrated: The scan tool displays Yes or No. Yes indicates speed range 2 is fully calibrated and the TPM system has full tire pressure detection capability from 65-95 km/h (40-59 mph). No indicates the TPM system is in the calibration process in speed range 2 and has no tire pressure detection capability in speed range 2.
Speed Range 3 Calibrated: The scan tool displays Yes or No. Yes indicates speed range 3 is fully calibrated and the TPM system has full tire pressure detection capability from 95-120 km/h (59-74.5 mph). No indicates the TPM system is in the calibration process in speed range 3 and has no tire pressure detection capability in speed range 3.
Speed Range 4 Calibrated: The scan tool displays Yes or No. Yes indicates speed range 4 is fully calibrated and the TPM system has full tire pressure detection capability from 120-145 km/h (74.5-90 mph). No indicates the TPM system is in the calibration process in speed range 4 and has no tire pressure detection capability in speed range 4.
Speed Range 1 Low Tire Detected: The scan tool displays Yes or No. Yes indicates the TPM system has detected a low tire pressure condition in speed range 1. No indicates the TPM system has not detected a low tire pressure condition in speed range 1.
Speed Range 2 Low Tire Detected: The scan tool displays Yes or No. Yes indicates the TPM system has detected a low tire pressure condition in speed range 2. No indicates the TPM system has not detected a low tire pressure condition in speed range 2.
Speed Range 3 Low Tire Detected: The scan tool displays Yes or No. Yes indicates the TPM system has detected a low tire pressure condition in speed range 3. No indicates the TPM system has not detected a low tire pressure condition in speed range 3.
Speed Range 4 Low Tire Detected: The scan tool displays Yes or No. Yes indicates the TPM system has detected a low tire pressure condition in speed range 4. No indicates the TPM system has not detected a low tire pressure condition in speed range 4.
TPM Indicator/Message: The scan tool displays On or Off. On indicates the TPM system has detected a low tire pressure condition and is commanding the IPC message center and the Driver Information Center (DIC) to display the LOW TIRE PRESSURE warning message. Off indicates the TPM system has not detected a low tire pressure condition and is not commanding the warning message to be displayed.
TPM Reset: The scan tool displays Yes or No. Yes indicates the DIC SET switch is being pressed during the TPM reset procedure. No indicates the DIC SET switch is not being pressed during the reset procedure.
TPM System Enabled: The scan tool displays Yes or No. Yes indicates the EBCM has been commanded by the scan tool to enable the TPM option. No indicates the EBCM has been commanded by the scan tool to disable the TPM option, or the TPM system has been disabled due to a system malfunction.
