Scan Tool Data Definitions - Tire Pressure Monitoring

LF Pressure Status
The scan tool displays the overall condition of the tire. The conditions that display are Unknown, Normal, Low, Flat and High.

LF Pressure Sensor Mode
This data parameter indicates the mode contained in the last transmission received from the left front tire pressure sensor. The scan tool displays Entering Off, Exiting Off, Rolling, Re-measure, Learn. Entering Off indicates the sensors internal roll switch is opened and the sensor has made its stationary transmission which only occurs once every 60 minutes from the last stationary transmission. Exiting Off indicates the sensor has transition to Rolling mode. In this mode the sensor has detected an initial roll switch closure. Rolling indicates the sensors internal roll switch has been closed for at least 10 seconds. In this mode the sensor is transmitting once every 60 seconds. Re-measure indicates the sensor has detected a 8 KPa (1.2 psi) change in tire pressure. This mode occurs to keep the system updated as to any changes in tire pressure. Learn indicates the sensor has been activated by a low frequency (LF) signal. Low Bat indicates the sensor's internal battery charge level is low. N/A indicates the sensor is in a mode not supported by the scan tool.

LF Tire Pressure
The scan tool displays 0-703 kPa (0-102 psi). The actual pressure of the left front tire.

LR Pressure Status
The scan tool displays the overall condition of the tire. The conditions that display are Unknown, Normal, Low, Flat and High.

LR Pressure Sensor Mode
This data parameter indicates the mode contained in the last transmission received from the left rear tire pressure sensor. The scan tool displays Entering Off, Exiting Off, Rolling, Re-measure, Learn. Entering Off indicates the sensors internal roll switch is opened and the sensor has made its stationary transmission which only occurs once every 60 minutes from the last stationary transmission. Exiting Off indicates the sensor has transition to Rolling mode. In this mode the sensor has detected an initial roll switch closure. Rolling indicates vehicle speed is greater than 32 km/h (20 mph). In this mode the sensors internal roll switch has been closed for at least 10 seconds and the sensor is transmitting once every 60 seconds. Re-measure indicates the sensor has detected a 8 KPa (1.2 psi) change in tire pressure. This mode occurs to decrease the time between when the pressure change occurred and the RCDLR has received it. Learn indicates the sensor has been activated by a LF signal. Low Bat indicates the sensors internal battery charge level is low. N/A indicates the sensor is in a mode not supported by the scan tool.

LR Tire Pressure
The scan tool displays 0-703 kPa (0-102 psi). The actual pressure of the left rear tire.

RF Pressure Status
The scan tool displays the overall condition of the tire. The conditions that display are Unknown, Normal, Low, Flat and High.

RF Pressure Sensor Mode
This data parameter indicates the mode contained in the last transmission received from the right front tire pressure sensor. The scan tool displays Entering Off, Exiting Off, Rolling, Re-measure, Learn. Entering Off indicates the sensors internal roll switch is opened and the sensor has made its stationary transmission which only occurs once every 60 minutes from the last stationary transmission. Exiting Off indicates the sensor has transition to Rolling mode. In this mode the sensor has detected an initial roll switch closure. Rolling indicates vehicle speed is greater than 32 km/h (20 mph). In this mode the sensors internal roll switch has been closed for at least 10 seconds and the sensor is transmitting once every 60 seconds. Re-measure indicates the sensor has detected a 8 KPa (1.2 psi) change in tire pressure. This mode occurs to decrease the time between when the
