Battery Voltage: The scan tool displays 8-14 volts. The amount of battery voltage available at the antenna module.

LF Pressure Sensor ID: The scan tool displays a number up to 8 digits in length, or an asterisk. A number displayed indicates the left front tire pressure sensors unique identification (ID) code, and that it has been learned into the antenna modules memory. An asterisk indicates the sensors ID code has not been learned into the antenna modules memory.

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 Stationary, Wake, Drive, Re-measure, Learn, Low Bat, or N/A. Stationary 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. Wake indicates the sensor is transitioning to drive mode. In this mode the sensor has detected an initial roll switch closure. Drive 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 11 kPa (1.6 psi) change in tire pressure. This mode occurs to decrease the time between when the pressure change occurs and when the radio antenna module receives it. Learn indicates the sensor has been activated by a low frequency 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.

LF Tire Pressure: The scan tool displays 0-344 kPa (0-51 psi). The actual pressure of the left front tire.

LF Tire Pressure Sensor Status: The scan tool displays valid or invalid. Valid indicates the left front tire pressure sensor is operating to specification. Invalid indicates that DTC C0750 is current.

LR Pressure Sensor ID: The scan tool displays a number up to 8 digits in length, or an asterisk. A number displayed indicates the left rear tire pressure sensors unique ID code, and that it has been learned into the antenna modules memory. An asterisk indicates the sensors ID code has not been learned into the antenna modules memory.

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 Stationary, Wake, Drive, Re-measure, Learn, Low Bat, or N/A.

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 11 kPa (1.6 psi) change in tire pressure. This mode occurs to decrease the time between when the pressure change occurred and the antenna module has received it. Learn indicates the sensor has been activated by a low frequency 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 0-344 kPa (0-51 psi). The actual pressure of the left rear tire.

LR Tire Pressure Sensor Status: The scan tool displays valid or invalid. Valid indicates the left rear tire pressure sensor is operating to specification. Invalid indicates that DTC C0760 is current.

RF Pressure Sensor ID: The scan tool displays a number up to 8 digits in length, or an asterisk. A number displayed indicates the right front tire pressure sensors unique ID code, and that it has been learned into the antenna modules memory. An asterisk indicates the sensors ID code has not been learned into the antenna modules memory.

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 Stationary, Wake, Drive, Re-measure, Learn, Low Bat, or N/A. Stationary 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. Wake indicates the sensor is transitioning to drive mode. In this mode the sensor has detected an initial roll switch closure. Drive 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 11 kPa (1.6 psi) change in tire pressure. This mode occurs to decrease the time between when the pressure change occurred and the antenna module has received it. Learn indicates the sensor has been activated by a low frequency 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.

RF Tire Pressure: The scan tool displays 0-344 kPa (0-51 psi). The actual pressure of the right front tire.

RF Tire Pressure Sensor Status: The scan tool displays valid or invalid. Valid indicates the right front tire pressure sensor is operating to specification. Invalid indicates that DTC C0755 is current.

RR Pressure Sensor ID: The scan tool displays a number up to 8 digits in length, or an asterisk. A number displayed indicates the right rear tire pressure sensors unique ID code, and that it has been learned into the antenna modules memory. An asterisk indicates the sensors ID code has not been learned into the antenna modules memory.
