For 1990-2009 cars only
LF Tire Pressure: The scan tool displays 0-100 psi. The actual pressure of the left front tire.

LR Tire Pressure: The scan tool displays 0-100 psi. The actual pressure of the left front tire.

Manual Tire Programing: The scan tool displays Active or Inactive. Active indicates the Tire Pressure Monitor (TPM) system is currently in the sensor programing mode. Inactive indicates the TPM system is not in the sensor programing mode.

RF Tire Pressure: The scan tool displays 0-100 psi. The actual pressure of the right front tire.

RR Tire Pressure: The scan tool displays 0-100 psi. The actual pressure of the right rear tire.

LF Tire Pressure Sensor Battery Status: The scan tool displays OK or Low. OK indicates the left front tire pressure sensor's internal battery level is good. Low indicates the left front tire pressure sensor's internal battery level is low.

LR Tire Pressure Sensor Battery Status: The scan tool displays OK or Low. OK indicates the left rear tire pressure sensor's internal battery level is good. Low indicates the left rear tire pressure sensor's internal battery level is low.

RF Tire Pressure Sensor Battery Status: The scan tool displays OK or Low. OK indicates the right front tire pressure sensor's internal battery level is good. Low indicates the right front tire pressure sensor's internal battery level is low.

RR Tire Pressure Sensor Battery Status: The scan tool displays OK or Low. OK indicates the right rear tire pressure sensor's internal battery level is good. Low indicates the right rear tire pressure sensor's internal battery level is low.

LF Tire Pressure Sensor Status: The scan tool displays Normal or Failed. Normal indicates the left front tire pressure sensor is in drive mode. Failed indicates the left front tire pressure sensor is in stationary mode.

LR Tire Pressure Sensor Status: The scan tool displays Normal or Failed. Normal indicates the left rear tire pressure sensor is in drive mode. Failed indicates the left rear tire pressure sensor is in stationary mode.

RF Tire Pressure Sensor Status: The scan tool displays Normal or Failed. Normal indicates the right front tire pressure sensor is in drive mode. Failed indicates the right front tire pressure sensor is in stationary mode.

RR Tire Pressure Sensor Status: The scan tool displays Normal or Failed. Normal indicates right rear tire pressure sensor is in drive mode. Failed indicates the right rear tire pressure sensor is in stationary mode.

LF Tire Pressure Transmitters: The scan tool displays Normal or Failed. Normal indicates the Remote Control Door Lock Receiver (RCDLR) is receiving tire pressure data transmissions from the left front tire pressure sensor. Failed indicates the RCDLR is not receiving tire pressure data transmissions from the left front tire pressure sensor.

LR Tire Pressure Transmitters: The scan tool displays Normal or Failed. Normal indicates the RCDLR is receiving tire pressure data transmissions from the left rear tire pressure sensor. Failed indicates the RCDLR is not receiving tire pressure data transmissions from the left rear tire pressure sensor.

RF Tire Pressure Transmitters: The scan tool displays Normal or Failed. Normal indicates the RCDLR is receiving tire pressure data transmissions from the right front tire pressure sensor. Failed indicates the RCDLR is not receiving tire pressure data transmissions from the right front tire pressure sensor.

RR Tire Pressure Transmitters: The scan tool displays Normal or Failed. Normal indicates the RCDLR is receiving tire pressure data transmissions from the right rear tire pressure sensor. Failed indicates the RCDLR is not receiving tire pressure data transmissions from the right rear tire pressure sensor.

Tire Pressure Sensor ID: The scan tool displays Valid or Invalid. Valid indicates all of the tire pressure sensors identification codes are valid. Invalid indicates that at least one of the tire pressure sensors Id codes are invalid.
