Scan Tool Data Definitions
Auto Learn Mode Active: The scan tool displays Yes or No. Yes indicates the TPM system is performing the calibration process for the speed range that the vehicle is in. No indicates the TPM system has completed the calibration process and has full capability of detecting a tire pressure condition for the speed range that the vehicle is in.
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.
Low Tire Pressure: The scan tool displays Yes or No. Yes indicates the Tire Pressure Monitor (TPM) system has detected a tire pressure condition and tire pressures should be inspected. No indicates the TPM system detects proper tire pressures.
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.
TPM Reset Switch: The scan tool displays Pressed or Released. The position or status of the reset switch.
Monitor Mode 1: The scan tool displays Active or Inactive. Active indicates the TPM system is in the initial calibration process and has no detection capability for a tire pressure condition for the speed range that the vehicle is in. Inactive indicates the TPM system has only partially learned the tire pressure calibration and has reduced tire pressure detection capability for the speed range that the vehicle is in.
Monitor Mode 2: The scan tool displays Active or Inactive. Active indicates the TPM system has fully calibrated the tire pressures and has full tire pressure detection capability for the speed range that the vehicle is in. Inactive indicates the TPM system is in the final calibration process and has limited capability for a tire pressure condition for the speed range that the vehicle is in.
